Release notes for the Foxglove web and desktop app.

Foxglove 3.5.0

October 28, 2026

🔑 Call the API with personal access tokens

Members on Pro, Enterprise, and Academic plans can create personal access tokens to call the Foxglove API as themselves, limited to the capabilities they choose. Open Settings → Personal access tokens to create one, then send it as a bearer token. Read more about Personal access tokens.

curl https://api.foxglove.dev/v1/devices \
  -H "Authorization: Bearer $FOXGLOVE_PERSONAL_ACCESS_TOKEN"

🔍 Search by pasted IDs and names, and export results

Paste a recording, event, or device ID, or a recording name, into the Search bar, and the suggestions include a matching query, such as @event.id == evt_…, along with Search with AI to run the text as an AI search. When a structured search returns no results, Fix my query opens the agent to diagnose it. Select results in the List or Gallery view and click Export CSV to download them. Read more about Building a query and Exporting results as CSV.

📜 Browse logs without moving playback

For recordings and files, the Log panel loads messages around the part of the log you're viewing, so topics with bursts and long gaps stay browsable. Scroll to browse the log, including past the current time, without seeking the other panels. Click Follow playback, seek, or start playback to follow the current time again. Read more about Timestamp navigation.

New & Improved

Dashboard: Open local file(s) and Open connection sit in the page header, and Upload local file, Compare local files, and Explore example data are in the ⋮ menu. Admins invite members from Settings → Members
Playback bar: the Show on timeline menu hides events on the playback timeline, or shows only the event types you pick
Agent sidebar: the agent creates, updates, and deletes events on a device. If you previously chose Always allow for event editing, approve Update events again
Agent sidebar: the agent lists events and reads event type properties and allowed values without an open visualization
Agent sidebar, Slack, and MCP: replies link devices, recordings, sessions, and other Foxglove objects to their pages
Slack: requests that don't name a Project use the oldest Project you can access instead of asking which one to use
Data source menu: Open in desktop app opens the current recording, session, or remote file in the desktop app at the current playback time — see Web vs. desktop
Data source menu: Copy link copies a working link for remote files, is disabled with an explanation for files opened from signed URLs, and is hidden for local files
Timeline: Coverage details has a Search in this range button that opens Search for the device and time range. On the Search page, it narrows the current search to the range selected on the results timeline
Recordings and Events: URLs and recording, event, and device IDs in metadata values are links, including inside longer values
Events: event types are marked with a solid diamond in the type's color, matching instant events on the timeline

API

Recordings: concurrent imports that share a session key no longer fail with a false device-mismatch error
Recordings: index-in-place recordings stay available after their object moves to another bucket path
Webhooks: notifications wait until the resources they reference can be read through the API, so follow-up calls made right after a notification find them
Pending imports and import errors: completed and failed imports are kept for 30 days, in Import errors and in the API
Site bucket notifications: Pro organizations can create notification tokens for their bring-your-own-storage sites instead of getting a Forbidden error
Primary Sites: ap-northeast-2 is available as an AWS bring-your-own-storage region

Foxglove 3.4.0

October 13, 2026

📈 Sync XY plots to a time window

An XY plot with Sync with other plots on now follows the time window of the plots it is synced with. Points inside the window stay at full opacity and the rest dim, so zooming a timestamp plot shows you which part of a path happened in that interval. Every point stays on screen, and the path doesn't rescale as the window moves. Read more about the Plot panel.

🔎 Search list pages by name or ID

Recordings, Sessions, Devices, and Device events have a search box above the list. Type to match a name or key, or switch the box to ID to find one exact record. The Filter menu has its own search that finds filter values and applies them in one click. Press F to open it. Read more about Filtering.

⌨️ Find any keyboard shortcut from the app

A searchable keyboard shortcuts drawer opens with Shift+? or from the user menu or command palette.

Foxglove 3.3.0

September 28, 2026

🗂 Expand one panel in a Stack

Panels inside a Stack have an expand control. Expanding one panel fills the workspace with that panel, and collapsing it restores the stack.

💬 Contact support from the app

Paid plans can reach Foxglove support from the profile menu or the command palette. Contact support opens a form in the app, and the request goes to the support team.

Recordings, Sessions, Devices, and Events add filters from a Filter menu. Each filter shows up as a removable chip instead of a row of always-visible inputs. You can add, edit, and apply filters from the keyboard. Read more about Filtering.

Foxglove 3.2.0

September 15, 2026

📊 State Transitions: one row per array index

Display each element of a primitive array as a separate row in the State Transitions panel. Set Array expansion to By index in the series settings. None stays the default, so existing layouts are unchanged. Read more about Expanding an array by index.

📈 Plot legend: hide, delete, and highlight series

Manage series directly from the Plot legend: toggle visibility, open settings from the color swatch, and delete individual, grouped comparison, or dynamic series. Hovering over a plot line highlights its matching legend and tooltip rows, including rows hidden by tooltip truncation. Read more about the Plot legend.

🎥 Play converted video in the 3D panel

The 3D panel can play H.264 (and other compressed video) carried on image topics when a schema converter maps them to foxglove.CompressedVideo. Choose Render as on the topic to project that video into the scene without recording a duplicate topic. Read more about Video.

New & Improved

Plot panel: expanded array series use shades of the parent color, and the same dynamic value keeps that shade across comparison sources — see Dynamic series

Recordings, Events, and Sessions galleries explain when a card has no preview because of the selected preview topic
Recordings, Sessions, Events, and Devices: breadcrumbs link back to the originating list or detail page and preserve list filters
Search: duplicate warnings collapse by message, and warnings identify missing queried fields and schemas or files omitted from results — see Search

Foxglove 3.1.1

September 4, 2026

🖼️ Gallery view is generally available

The Gallery view for Recordings, Events, and Sessions is generally available, alongside the existing Details view.

The view toggle also covers all three data tabs on a device's detail page, and the view you pick lives in the URL, so ?view=gallery opens straight into the gallery and travels with a copied link.

Foxglove 3.1.0

September 2, 2026

📈 Step interpolation for Plot series

Plot a discrete signal, such as a gear, a mode flag, or an enum, as a held step instead of a sloped line that implies a transition that never happened. A Line interpolation setting on each Plot series switches between Linear and Step.

🖼️ Recordings, Events, and Sessions open in a resizable side preview

Open a card on the Recordings, Events, or Sessions page and its details slide in beside the grid instead of taking over the screen — resizable, arrow-key navigable, and closable with Esc. Even a recording or event with no camera shows a preview, like a path, map, log, or plot. In the list views, the header stays pinned as you scroll, and you can resize columns or double-click to autosize them.

🎥 Play H.264 video from CompressedImage topics

The Image panel can now play H.264 video carried in sensor_msgs/msg/CompressedImage when a schema converter maps it to foxglove.CompressedVideo. Hardware encoders such as NVIDIA's isaac_ros_h264_encoder can keep video on the standard ROS type without recording a duplicate topic or maintaining a bridging node. Read more about Supported encodings.

🔗 Slack unfurls your Foxglove links

Paste a Foxglove /view link into Slack and Foxglove expands it with details about the recording, session, event, or device it points to. Read more about the Slack integration.

New & Improved

3D and Image panels: with timestamp sync on, transforms can be required at the exact match time, so a frame whose transform is not at that timestamp waits instead of posing against a stale one
3D and Image panels: camera calibration can join timestamp sync, so a panel waits for a calibration message at the matched time instead of using the latest one
3D Maps: on plans without access, the Add 3D Map action stays visible but disabled, with upgrade guidance; eligible layouts suggest a map once location data is ready
Agent sidebar: clearer guidance for choosing among a user script, a schema converter, and a topic converter
Agent sidebar: append or delete a tab in an existing Tab panel with a scoped write that keeps your current tab active
Agent sidebar: a play_until control plays forward and pauses at a target, preserving stateful panel data that a seek would clear
Agent sidebar: edits to a user script patch the relevant part of the file instead of rewriting the whole thing
Sessions: Edit key in the session overflow menu changes a session key after creation, or clears it
Sidebar: Open local file and Open connection are shown only on the visualization view and the dashboard cards, so the sidebar on other pages is browse navigation only
Dashboard and sidebar: a Compare local files action opens two or more local files in comparison mode
Remote Data Loader: open more than one source on a single dataLoaderUrl and merge or compare them, using the same Data Source sidebar switch as cloud recordings and remote files — see Shareable links
Example data entry points are relabeled Explore example data for clearer navigation
Embed: an embedded page can own the live connection and stream the Foxglove WebSocket Protocol to the viewer from the parent page

3D panel: custom URDF layers that source /robot_description now load
Search: results that identify only a device now show a preview
Search: results table columns line up with their headers
Search: the details panel no longer leaves an empty band above its footer
Search: a preview that fails to load no longer shows as an empty result, and the details topic picker keeps its Auto option after you choose a single topic
Events sidebar: no longer gets stuck loading on recordings with no associated device
Events: a failed bulk delete no longer leaves a stale row that blocks retries, and a successful delete stays on the current page instead of jumping to the first
Events: deleting a group of events no longer fails outright when one was already deleted
Remote Access: the session now recovers gracefully from a corrupt LiveKit byte stream instead of stalling with an unparseable-JSON banner
Recordings: re-indexing a bring-your-own-storage recording after its device metadata is removed succeeds and keeps the same recording
Recordings: the table keeps your selection when the list refreshes
Recordings: bulk actions respect the metadata search, so Select all matching recordings no longer acts on more than the list shows
Sessions: the table sorts the full result set and matches the gallery's sort control
Agent sidebar: opening the Dashboard while the chat dock is closed now shows an empty chat instead of the prior conversation

Foxglove 3.0.0

August 18, 2026

Foxglove's built-in agent builds layouts, writes user scripts, runs your request as a query on Search, and answers questions about your data. Read-only tools run on their own; anything that makes a change waits for your approval. The agent sidebar is available on all plans. Read more about Agent sidebar.

🔀 Comparison mode: debug what changed between runs

Select two or more recordings, sessions, or events from real-world logs or simulations, and click Compare to put them on one shared visualization timeline. Each source takes a slot labeled A, B, C, and so on; Plot, State Transitions, and Map draw every slot at once, while single-source panels such as 3D show one at a time. Comparison mode is generally available on Pro, Enterprise, and Academic plans, for basic and developer seats. Read more about Comparison mode.

🔎 Semantic search: find image frames and actions by describing them Beta

Query your data by describing the action your robot took (semantic search over video embeddings) or what's in the frame (image embeddings). Combine a visual prompt with other query fields, for example visual("package dropped") and /robot_state == autonomous, to search recordings' image and video topics alongside other log data. Visual search is in beta on Pro and Enterprise plans; contact sales for access. Read more about Semantic search.

📊 Grafana integration: query Foxglove data in your dashboards

The Foxglove data source plugin, published in the Grafana plugin catalog, turns a FoxQL expression such as /imu.linear_acceleration.x into a time series, using the same query engine as the Search page. The plugin queries the Foxglove data platform directly, so you can build Grafana dashboards on your data in Foxglove. Contact sales for access. Read more about the Grafana plugin.

The Foxglove data source plugin in the Grafana plugin catalog, with a query editor charting a message path as a time series

🗄️ Bring your own storage: general availability

Bring your own storage (BYOS) is generally available (GA) across AWS, GCP, and Azure. Keep your recordings in the cloud storage bucket they already live in while Foxglove indexes each file in place so you can query and stream it, without duplicating or moving your data. Contact sales to get started. Read more about Foxglove Cloud, bring your own storage.

🔌 Desktop MCP server: general availability

The desktop app's local Model Context Protocol (MCP) server is generally available, with access to the same tool catalog as the agent sidebar. Turn on Local MCP server under Settings → Personal → Agents & MCP. The Desktop MCP server is available on Pro, Enterprise, and Academic plans. Read more about Desktop MCP.

New & Improved

Fleet: the on-device process that monitors and uploads recordings is now called Foxlet across the app and the docs; package, binary, and path identifiers are unchanged — see Foxlet
Gallery: opening a result shows the details panel, and cards animate into their re-wrapped positions
Gallery: on a narrow window the details panel takes over the screen instead of squeezing the cards beside it
Search: previews follow the pointer as you scrub, and topic chips in a result's details switch the preview to the topic you click
Search: a shared link opens Gallery with the preview topics the sender pinned — see Gallery
Search: queries mix AND and OR without parentheses; AND is applied first — see Search
Search: parentheses nest to any depth, and a ?query= link created before 3.0.0 opens with an empty query bar; saved searches and recents are unaffected
Search: a recording's Source Details shows the query summary with its grouping parentheses, at any depth
Search: topic autocomplete matches fuzzily, so a topic turns up without typing the start of its path
Search: the empty state offers Import data when an organization has nothing to search yet
Search: device and time-range results list the sessions covering that device and range in List view
Recordings: a multi-recording visualize view downloads one merged MCAP spanning every recording; comparison views don't offer Download, because that export would be incomplete
State Transitions: the legend is called series labels, and hiding it compresses each row so more series fit on screen — see State Transitions panel
Image panel: decodes 12-bit Bayer raw images (bayer_rggb12, bayer_bggr12, bayer_gbrg12, bayer_grbg12) — see Supported encodings
Panels: double-clicking a panel title expands or collapses it
Panels: action buttons have clearer spacing and stay easier to see
Playback: the playback range editor snaps to the playhead, and while its dialog is open, keyboard shortcuts and command palette entries trim the range to the playhead or reset it — see Controls and shortcuts
Performance sidebar: Export diagnostics saves a JSON troubleshooting report, which stays on the machine until you share it
Performance sidebar: charts label and scale automatically, readings align, and a warning appears when hardware acceleration is unavailable
Plot panel: adding a series expands, scrolls to, and highlights it in the settings sidebar
Tables: the action bar on Recordings, Sessions, and Events stays pinned to the top while you scroll
Filters: the Recordings, Events, and Sessions filter rows stay compact at narrower window widths
App bar: the sidebar toggle buttons stay highlighted while their sidebar is open
Embedding: basic-seat members can open layouts supplied by an embedding application — see Embedding Foxglove
Admin: the Enterprise usage page shows current seat counts alongside infrastructure credits
Remote data loader: a stream failure names the loader and shows its error in the Problems sidebar

Performance

Plot and State Transitions load faster on bring-your-own-storage sites, with nothing to configure
Search: faster topic discovery on large sites
Gallery: loads faster when a query returns many results
Recordings: the page loads faster in projects with many recordings
The layout menu opens faster

API

API keys: a request missing a capability returns the MissingApiKeyCapability code and names the capability it needs
Saved searches: GET /v1/saved-searches/{id} returns a working run URL. Re-save a search created before 3.0.0 to refresh that URL
Remote data loader: shareable links carry manifest query parameters in ds.manifestParams, and links in the earlier flat form still open — see Shareable links

Fixes

Desktop: signing out shows the sign-in screen instead of looping on "Signing out…"
Desktop: standalone-license mode no longer crashes on the dashboard, the examples page, or the onboarding wizard's examples step
Desktop: quitting no longer raises a JavaScript error dialog
Playback: a Data Platform stream that closes during inactivity no longer fails playback
Playback: merged data sources whose time ranges don't overlap play and scrub without errors
Gallery: no longer crashes on very large result counts
Gallery: arrow keys step through cards instead of scrolling the page, and the focused result stays in view as the details panel opens or closes
Search: video previews still play when the keyframe is before the result window, the file is large, or the result matches more than one topic
Search: the query field no longer flashes "Loading topics…" on refocus or expands to two rows on narrow windows, and the topic picker settles as it closes
Search: the results page no longer shows duplicate decade labels, doubled or missing dividers, a misaligned query status bar and sort control, or a details panel that overflows its boundary
Search: backward date navigation stops at the earliest supported date, and durations longer than a second read in compact units
Search: a FoxQL function suffix such as .@abs reports an error instead of silently returning results for the untransformed value
Search: results no longer shift horizontally when the page scrollbar appears
Map panel: timeline previews highlight the matching position in every comparison slot
Plot panel: warning icons no longer flicker while you hover a comparison badge, and no spurious warning triangle appears when a series or comparison slot becomes active
Plot and State Transitions: Label field and Value field settings appear only for expressions that are dynamic series
Video export: exports run when the data source has reported unrelated errors, and console errors read as messages instead of internal identifiers — see Video export
Panels: an expanded panel collapses back to its current position after the workspace is resized
3D panel: map tiles load without waiting for a camera or playback-time change
Performance sidebar: data throughput reads correctly for local and cloud recordings
Timeline: a recently added device shows its current name instead of a stale cached one
Projects: keyboard navigation works in the project picker
Organizations: inviting basic-seat members works when an organization has reached its paid seat limit
Agent sidebar: plots of ROS timestamps use the units you asked for
Onboarding: the quickstart's sample drone stream no longer ends getting-started guidance before you have viewed your own data

Foxglove 2.59.0

August 4, 2026

🔌 Desktop MCP server

The Foxglove desktop app can run a local MCP (Model Context Protocol) server so external coding assistants like Claude Code, Cursor, Claude Desktop, and other MCP clients can see and control Foxglove. Your agent can access the Data Platform, search your organization's recordings, sessions, and events, build layouts, write user scripts, control playback, and search the docs. Turn on Local MCP server under Settings → Agents & MCP; it needs a Pro or Enterprise plan and a developer seat. Read more about Connect your own agent (MCP).

🔍 Search with FoxQL and Gallery previews

Find the right recording faster: write a FoxQL query over devices, metadata, topics, and message fields, then review matches as Gallery preview cards before you open one. List and Timeline views stay one click away. Read more about Search.

New & Improved

Foxlet Settings: Auto-delete local files after import deletes each recording from the device after Foxlet uploads it — see Delete recording files
Plot panel: clearer warnings for out-of-range array slices and matched values that cannot be plotted
Raw Messages panel: improved header layout across narrow and wide panel sizes
Playback: the timeline info (i) button opens the Sources sidebar; with an active search query it opens the Source Details modal so you can review or clear the query
Recordings: the list renders as soon as it loads instead of waiting on pending imports
Command palette: type a project name to switch projects or open the Projects page
Search: tidied spacing in the query bar's suggestion menu
Search: the query bar drops its clear (×) button — select and delete the text to clear a query

API

Embedded viewer SDK: open a session by ID or key — see Changing the data source

Fixes

Navigation: clicking the entry for the page you are already on no longer discards that page's state, such as the active search, its time range, and its view mode
Local files: reopening after a page refresh no longer fails when browser read access has lapsed — a dialog lists the files that need it and Allow access requests them all at once
Search: topic pickers no longer obscure their triggers when opened
Events sidebar: timeline events no longer remain stuck in a loading state
Extensions: an organization extension now updates to the registry's latest version even when a local extension with the same ID is installed

Foxglove 2.58.0

July 29, 2026

📈 Plot panel: one sub-series per array index

Messages often pack related values, such as accelerometer axes or joint positions, into a numeric array. The Plot panel's timestamp plots offer an Array expansion setting: choose By index to draw one sub-series per array element, labeled with its source index. None remains the default, so existing layouts keep their current behavior, and ranged slices retain their source indices. Read more about Array expansion.

🔍 Search from the Raw Messages panel

Hover over a value in the Raw Messages panel and choose View in Search to open Search with a query for that message path and value, scoped to the recording's time range. The same action on the message header searches for any message on that path. Search returns results from recordings that have been indexed. Read more about Search.

⌨️ Keyboard shortcuts for message stepping

Read a topic message by message without reaching for the mouse. With the Raw Messages panel selected, Alt+[ and Alt+] (Option on macOS) step to the previous and next message on that panel's path. Read more about Message stepping.

🔗 Visualize multiple recordings merged as one

Select two or more imported recordings on the Recordings page and choose Visualize to open them merged into a single timeline, without creating a session first. Topics from every recording share one playback range, and the app bar lists each recording. The Source info sidebar opens with a Merged section spanning the full combined range, followed by the name and time range of each source.

New & Improved

Gauge panel: an Origin setting grows the fill outward from a chosen value, with an optional Mirror color at origin toggle for a diverging color ramp
Plot panel: series settings show the same error and warning indicators as the plot legend, flagging missing topics, invalid paths, timestamp problems, and series with no matching data
3D panel: in object inspection mode, a click that intersects several objects opens a disambiguation menu labeling each one with its object ID alongside the topic
3D panel: hover tooltips show up to 5 metadata rows plus a count of the rest, so tooltips for objects with large metadata collections no longer cover the panel
Map panel: highlighted locations use a more saturated color that stays legible in both light and dark themes
Remote data loader: connection failures report a network error within about 10 seconds, with VPN and firewall guidance and a Retry button
Remote data loader: the Problems sidebar shows the error message the upstream service returns, such as an expired recording link
Command palette: Switch project drills into a searchable project list, so you can change projects without leaving the keyboard
Billing: Enterprise plans can view their usage from Settings → Billing
Bring Your Own Storage (BYOS): the bucket notification commands for AWS and Azure filter to .mcap and .bag files — see Configure bucket notifications for the current commands
Search: results scroll with the rest of the page, and the query bar and results toolbar pin to the top
Search: the time range picker has previous and next arrows that shift the range by its current duration
Date pickers: Last 3 months, Last 6 months, and All time join the existing shortcuts, and Search opens on Last 6 months when no other range is set

Performance

Smoother playback above 1x speed
Raw Messages panel: faster rendering during playback while the message stepping controls are visible
Map panel: no interface freeze while a dense location topic loads its history

API

BYOS: provisioning a site turns on search indexing and automatic ingestion from the start
BYOS: search indexing treats a recording with a missing source file as deleted, so it leaves the search index even when the bucket never sends a delete notification

Fixes

Plot panel: empty primary and secondary y-axis placeholders use distinct colors that stay stable as you configure either series
Plot panel: each series downsamples against the visible range of its own y-axis, so narrow peaks on the secondary axis stay visible
Plot & State Transitions: ROS header stamps render for topics streamed from Data Platform
State Transitions: a series that matches no data says so, and a custom timestamp method without a path reports the missing path
Log panel: the log list fills the available panel height on live connections
Map panel: current location markers use the same color as the matching Plot series
Panel selector: stays inside the center pane instead of drawing over a widened sidebar
Panel settings: the visibility and sync icon buttons keep a pointer cursor across the whole button
Playback: removing a panel mid-playback no longer stalls playback for several seconds
Remote Access: the device filter in the connection dialog persists when you switch connection tabs and return
Search: date ranges longer than 10 years survive editing in the time range picker and sharing by URL
Search: the dropdown carets in the query builder sit beside their text instead of overlapping it
Search: the time range picker no longer shows a hover tooltip
Search: the results details tooltip drops redundant lines and labels each stat
Date pickers: the selected shortcut name renders instead of the raw dates, and each picker hides shortcuts longer than its maximum range
Pending imports: hovering over a truncated error message shows the full text
Extensions: the visualization and the Installed extensions list show a loading state until the organization's extensions finish syncing, instead of briefly reporting no extensions
Custom properties: type icons stay inline with their labels instead of wrapping above them
Custom properties: the event type and custom property sidebars label each type as Single-select or Multi-select instead of enum and multi-enum
Fixed exports of zero-duration recordings so they cover the whole recording
Fixed the offline licensing portal showing a blank page
