Foxglove 3.2.0

📊 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
  • Use the Command palette to start a local-file comparison or add, switch, remove, and adjust comparison sources by name — see Comparison mode
  • Image panel: decodes 12-bit RCCG raw images (rccg12) — see Supported encodings and Color correction for RCCG images
  • 3D Maps: Altitude Reference samples ground altitude at the current location, and can align altitude automatically by sampling the map
  • Publish panel: Cmd+Enter (macOS) or Ctrl+Enter publishes from the message editor — see Controls and shortcuts
  • Topics sidebar: a topic's actions menu opens it in a Raw Messages panel
  • Layouts: when Visualize has no layout selected, Generate layout for this data builds a personal layout from the open data source's topics
  • Gallery: URLs preserve the selected preview topic, the open state of the details panel, and current page across Recordings, Events, Sessions, and Search. Shared links and the browser's Back button restore that view — see Choose preview topics
  • 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
  • Events: The Created By field shows the user's profile name, or Unnamed user when none is set
  • Devices: drop multiple recordings or a folder onto a device's details page to upload them — see Import files
  • Foxlet: an import that failed to upload can be retried from the app — see Diagnose and resolve errors
  • Bring your own storage: a quarantined import can be retried or downloaded from the app — see Diagnose and resolve errors
  • Remote Access: data topics are compressed in transit — see Remote Access
  • Sources tab: the left sidebar reports server version information for WebSocket and Remote Access connections
  • Embed: a parent page can own the Remote Data Loader connection and issue loader requests itself — see Parent-owned remote data loader transport
  • Extension panels can read the live WebSocket data source's host and port from RenderState.connection — see RenderState
  • Desktop: update notices appear as small cards in the bottom-right corner instead of a full-width banner
  • Japanese and Chinese translations cover previously untranslated UI, including the external MCP server settings
Performance
  • Local and remote indexed MCAP files scrub more smoothly
  • Remote files load and seek faster
  • The Recordings page loads faster for organizations with many recordings
API
  • Sites: configure ingest path policies to control which objects bucket notifications import, including index-in-place — see Configure bucket notifications
  • Saving an unchanged ingest path policy no longer creates a duplicate revision
Fixes
  • Agent sidebar: seek links that target a time outside the current playback range are rejected instead of seeking off-range
  • Agent sidebar: a 3D panel no longer reports missing frames while its transforms are still loading
  • Agent sidebar: failures show the correct error instead of defaulting to a connection problem, and Retry resumes failed messages, continuations, and tool results
  • 3D Maps: tiles continue to load after a Google tile session expires
  • 3D panel: compressed Draco point clouds keep updating at high playback speeds
  • State Transitions: editing or deleting a series no longer reloads the others

  • Playback: Left and Right move the eligible event or playback-range endpoint in that direction
  • Recordings: organizations with multiple sites can use the Site filter without an edge site or Foxlet
  • Recordings: Select all matching recordings now visualizes, compares, or adds to a session every recording the filter matches, not only the current page
  • Sessions: bulk delete no longer fails under load, and deleting a session refreshes its recordings
  • Sessions: comparison selections stay selected when you change or clear filters
  • Search: a large result set no longer raises an application error as gallery cards stream in
  • Remote Access: a session no longer reconnects unexpectedly during normal operation

Downloads: Linux: deb amd64 arm64, snap amd64 | Windows: x64 arm64 | Mac: Apple Silicon Intel

Foxglove 3.1.1

🖼️ 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

📈 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
  • Timeline: an All time range loads the full history from 1970 through today, and the URL preserves it
  • Timeline: when the selected range is empty, a one-click Expand to … button jumps to a wider range that contains recordings, and browser Back restores the original range
  • Recordings, Events, and Sessions share one bulk-actions toolbar that stays pinned while the table scrolls and that wraps to fit narrow windows, and Events and Sessions gain bulk delete
  • Recordings, Sessions, and Device events: a Clear filters control resets every filter field at once, leaving sort order unchanged
  • Recordings: an End time column, hidden by default, can be shown from Manage columns
  • Search: autocomplete now suggests fields, operators, and values for topics whose names don't start with a slash — see Search
  • Search: the gallery, query status bar, and details panel now line up on a shared edge
  • Previews: the Auto image shows a color camera instead of a depth camera when a recording has both
  • Command palette: commands you can't run are hidden instead of shown grayed out
  • Command palette: an Adjust playback range command opens and closes the range editor by name from the keyboard
  • Panels: the empty-layout panel picker is navigable with the arrow keys and Enter
  • Plot panel: a top legend starts one row tall and grows only as far as its rows need, leaving more room for the chart
  • 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
Performance
  • Recordings load faster when filtered by a device and sorted by import time
  • Recordings filter faster when scoped to a site on bring-your-own-storage projects
  • The Sessions page loads faster for organizations with many recordings
  • Listing events sorted by creation time is faster
  • 3D panel: the camera stays responsive while you pan or rotate scenes with many transforms or meshes
  • Previews in the Recordings and Sessions galleries load from the browser cache on revisit instead of re-fetching and re-decoding
API
  • Sessions: PATCH /v1/sessions/{keyOrId} changes a session key after creation, or clears it with null
  • Recordings: responses include an optional location field with the object-store path and bucket for bring-your-own-storage and index-in-place recordings; recording.imported webhooks for device and contentId re-uploads now include site, device, and edgeSite
Fixes
  • Dashboard: double-clicking a recently viewed item opens it reliably on the first try instead of showing a blank screen
  • Desktop: double-clicking a recent item in the visualization menu opens it and no longer toggles fullscreen
  • Desktop: opening a second window on Windows no longer flickers between the two
  • Desktop: signing out stops the local MCP server instead of leaving it listening
  • Panels: an expanded panel stays expanded when its configuration is updated through MCP
  • Plot panel: timestamp plots show complete data after panning, zooming, or applying synchronized X bounds
  • Plot panel: XY series that use a panel-level x-axis expression stay on the right x values after a series is hidden or its x-axis expression is deleted
  • Plot panel: dynamic sub-series render against their configured y-axis, and hover and measurement tools resolve the right series
  • Plot panel: the downsampled indicator clears when the x-axis is switched away from timestamp
  • State Transitions panel: the tooltip no longer shows an empty placeholder row for a sub-series with no value at the cursor
  • Playback: the Adjust playback range handles now stop at the edge of the recording instead of producing timestamps far outside it
  • Video export: a failure after encoding starts now leaves a playable partial video
  • Clicking a numeric setting or a recording segment tolerates a small pointer movement instead of treating it as a drag
  • Map panel: overlapping members of a GeoJSON MultiPolygon fill as a solid shape instead of showing holes
  • 3D Maps: maps now load in embedded Foxglove views
  • 3D panel: the camera no longer jitters while you rotate or pan large scenes
  • 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

🤖 Agent sidebar: a built-in agent to work on your data Beta​

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

  • 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

  • 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

Remote Data Loader v0.0.11

This release fixes a CORS issue, adds support for x-foxglove-error-message header to streaming sources and improves lookback.

Added
  • Data backends can now surface a human-readable error message when a streamed data request fails, not just when a manifest request fails, by setting the x-foxglove-error-message response header. See the development guide for details.
Fixed
  • Fixed CORS errors on the root endpoint when the app would load
Changed
  • Replay lookback now returns every message at a channel's latest timestamp before the seek, instead of an arbitrary one when several messages share that timestamp.

Foxglove 2.59.0

🔌 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
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

Foxlet v1.5.0

Foxlet​

This release adds recording auto-delete settings.

New & Improved
  • Added support for automatically deleting local recording files after auto-import

Docs: About, Install | Debian Packages: amd64, arm64 | Binary Files: amd64, arm64

Primary Site v0.0.106

When resolving a recording's context, this release merges every "foxglove" MCAP metadata record in the file, rather than using only the last one. Later records override earlier keys, and an empty string value unsets a key. To keep the previous behavior, set the following in your values.yaml, on whichever component your indexing strategy deploys:

inboxListener:
  deployment:
    mergeFoxgloveMcapMetadata: false

This release also adds an optional beta stream executor, which can substantially improve streaming throughput on multi-core query service pods. It is off by default.

Added
  • Added a beta multi-threaded stream executor that reads a stream's MCAP chunks across parallel partitions, off by default behind queryService.deployment.enableBetaStreamExecutor
Changed
  • Merged all "foxglove" MCAP metadata records when resolving recording context, instead of using only the last record. Set mergeFoxgloveMcapMetadata: false on the indexer or inbox listener deployment to restore the previous last-record-only behavior
Fixed
  • Improved query service error messages when a stream fails mid-response
  • Fixed values.yaml validation, which was silently skipping its required-setting checks
