📐 3D measurement tool: snap to scene objects​

The 3D panel's measurement tool can now snap endpoints to scene objects so you can measure between exact features instead of approximating with the cursor. Hold Alt / Option to enable snapping for that endpoint. Combine snapped and free-space endpoints in a single measurement, and read out per-axis projections alongside the total distance.

🕰️ Absolute timestamps in Plot and State Transitions​

Plot and State Transitions panels can now display absolute timestamps on the x-axis instead of seconds elapsed since the start of playback. Pick Absolute under the new Timestamp display setting and ticks render using the global time format and timezone.

🕒 Per-topic timestamp sync in 3D and Image panels​

The 3D and Image panels' "Sync timestamps" (formerly Strict time sync) toggle is no longer all-or-nothing. Each topic now has its own Sync opt-in in the Topics section. Mix high-frequency and low-frequency topics in the same view and choose which ones must line up before rendering, instead of a single slow topic blocking everything. In the Image panel, the primary image and its visible ImageAnnotations always sync together; in 3D, layouts with sync enabled now need to opt topics in.

New & Improved

• Gauge panel: configurable value ticks in both dial and bar modes (enable Show ticks in panel settings and set a Tick interval); the panel also follows the app's light/dark theme
• Search: the time range is now a built-in filter at the top of the query builder (and surfaces in the collapsed query summary), so it's obvious as a search constraint instead of a separate header control
• Search: the query builder auto-collapses to its summary after running a query so results aren't pushed off-screen — the Running… indicator and Cancel button stay visible while a search is in progress
• Search: results show recording filenames (with the full path on hover) and dot-style colored event-type labels in place of raw IDs; the raw recording ID is preserved as an optional column
• Search: list view shows a clear empty state when a query returns zero results, suggesting users adjust the time range or query conditions
• Search: the active date range is preserved when returning from the visualizer via "Back to search", so prior queries no longer appear empty after the round-trip
• Search: Recording key is now available as a first-class field for filtering and display in recording results
• Search: the query builder infers the data type of message field paths from the topic schema and restricts operator choices to ones valid for the field's type (number, string, boolean)
• Search: the "incompatible sites" warning now shows actionable upgrade instructions with a copyable helm upgrade command and a link to the upgrade guide, replacing the old "Manage sites" dead-end
• Panel settings: section expansion state and scroll position now persist locally across page reloads, per panel
• Plot panel: scalar message-path functions (such as delta, derivative, and degrees) are now suggested in autocomplete for fields on schemaless topics
• Audio panel: a volume slider in the panel toolbar lets users adjust volume and mute without opening panel settings
• Audio panel: shows a clear "No topic selected" empty state when no topic is configured, instead of a blank waveform
• Source info sidebar: shows the Primary site and (when enabled) Edge site for the loaded recording, matching the recording detail page
• Source info sidebar: Attachments rows now have dividers like the rest of the sidebar lists
• Recording detail: metadata records on the Metadata tab are visually nested under each Name: header with a divider line between groups, so multi-record recordings read at a glance
• Device properties: each property row has a View History action on hover that opens the property history tab pre-filtered to that key
• Device property history: saving a record automatically expands the active time range to include the saved interval, and the default range is widened to 30 days
• Org settings: admins on Pro and Enterprise plans can pick a Default seat type for new members from the General settings page
• Sign-in flows: a language selector on the welcome / sign-in / sign-up pages lets users change app language before signing in (desktop only)
• Recordings page: removed the rarely-used "Poll for new imports / Poll for recording updates" toggle; pending imports still refresh on completion and the recordings list refreshes on load and navigation

Performance

• Improved Search page load speed
• Improved playback performance for remote MCAP files

API

• Note: accessing Recording key in Data Search requires self-managed primary sites on version 0.0.101 or later. Foxglove-hosted sites are unaffected.

Fixes

• Data Search: the Cancel button now reliably stops long-running queries once results have started streaming in (the spinner cleared and the button replaced with Run)
• 3D panel: compressed video rendered as image planes (with cameraInfo projection) no longer lags several frames behind the rest of the synchronized scene at slow playback speeds
• Plot panel: deleting a series no longer changes the displayed color of other series that did not have an explicit color stored
• MCAP support: fixed loading of MCAP files whose JSON Schema channels use string-valued oneOf enums (including schemars-generated schemas)
• MCAP / IDL: fixed broken deserialization of messages whose union discriminator does not match a case in the IDL spec
• Recordings, Sessions, Events, and Devices pages: filter inputs use the same compact sizing as inputs in visualization panels (matching the smaller height used by panel settings)
• Desktop: fixed a Windows packaging issue that could leave shipped app executables unsigned

🔍 Data Search: query recordings, events, and messages​

Build visual queries across messages, events, devices, recordings, and sessions with the new Search page, and stream results into a sortable table—no query syntax required. Search works across data hosted in Foxglove Cloud or on your self-managed primary site, with no separate data warehouse to set up or duplicate data to keep in sync. Read more about Data Search.

💰 New self-service pricing and unlimited Basic Seats​

The Team plan is now Pro and starts at $20/month for 1 TB of storage and 3 Developer Seats (down from $126/month for 3 seats, over $100/month in savings), and meters now have volume-based discounts as usage grows. Data Search is included on Free, Pro, Academic, and Enterprise plans; Pro and Enterprise also include unlimited Basic Seats at no extra cost. Customers migrated from Team to Pro will see updated prices on their next full billing cycle. Read more about our new self-service pricing, and try the cost calculator.

🪑 Basic Seats: free seats on Pro and Enterprise plans​

Pro and Enterprise plans now include unlimited Basic Seats at no extra cost: a new seat type for teammates who visualize Foxglove-hosted data with existing layouts, without authoring their own layouts or loading local files. Pair them with Developer Seats for full authoring access to bring ops, leadership, field teams, and contractors into your workspace without per-seat costs. Read more about Basic Seats.

Basic Seat members must use Foxglove 2.51 or later on desktop to sign in.

🗄️ Bring Your Own Storage: keep raw data in your own cloud​

Enterprise plans can now connect Foxglove to an existing AWS S3, Google Cloud Storage, or Azure Blob Storage bucket. Foxglove manages indexing, query, and visualization while your MCAP recordings stay at rest in storage you control. Pair it with Data Search to index and query petabytes of data without duplicating it into Foxglove. Usage-based pricing means you only pay for indexing, query, and bandwidth, with no charge for storage you already own. Read more about Bring Your Own Storage, or contact sales to enable it.

New & Improved

• Event visualization: opening an event now pads the player with 5 seconds of context before and after the event time range so point events and short ranges are usable; URL start / end parameters still override the padded range when you adjust the timeline and share the link
• Raw Messages panel: when multiple messages share the newest receiveTime, inline controls step through that group in stream order before falling back to the previous timestamp
• Problems sidebar and Raw Messages panel show source-mapped stack traces for schema converter errors
• Image panel: Show all and Hide all annotation topics in one click from the annotations settings
• 3D panel: GridMap topics support a Flat elevation option that renders the grid as a flat plane without elevation displacement
• Events: pick a custom hex color for an event type from the color picker's More colors option, in addition to the built-in palette
• Billing: a new Usage tab embeds your live usage portal alongside the existing Plan tab
• Storage, bandwidth, and usage figures throughout the app and billing reports now use SI units (MB, GB, TB) instead of mebibytes/gibibytes
• Desktop: tab bar aligns with the navigation sidebar and removes the extra border under the active tab
• Command palette: Improve translations (non-English locales), matching the existing user menu entry
• User scripts: added eulerToQuaternion() to the built-in quaternion helpers (inverse of quaternionToEuler())

Performance

• Improved playback performance for remote file data sources

API

• Device property history is documented and publicly available in the API (internal gating removed)
• Device tokens and device agent capabilities are now available on every plan in Settings, API key scopes, and the device token API
• Self-managed primary sites must be on 0.0.100 or later to be considered searchable by Data Search; older sites show as incompatible. Foxglove-hosted sites are unaffected.

Fixes

• Fixed arrow-key handling so panels that use their own keyboard navigation no longer also trigger global playback seek (capture-phase shortcut regression)
• Tab panel: the entire tab header is wired to the panel drag handle again, so dragging a Tab panel by its header repositions it within the layout
• Recordings page: selecting a row no longer shifts the table downward—the bulk-actions bar now overlays the header instead of pushing rows out of the way
• Plot panel: supported message path functions in X-value path and the default X-axis path are no longer flagged as invalid in settings
• Plot panel: floating legend no longer overlaps Y-axis tick labels (legend shifts horizontally based on the gutter width)
• 3D panel: textures referenced from OBJ material libraries load correctly for package:// and file:// assets
• 3D panel: image rendering no longer leaks GPU memory when an image topic switches between compressed video frames and raw image data
• 3D panel: GridMap settings preserve the configured elevation layer while topic layers load, eliminating a brief "Layer does not exist" validation flicker
• Color picker: incomplete hex values (e.g. #ab) no longer commit on each keystroke—values commit on blur, Enter, or wheel; the popover's Enter key now closes the picker as expected
• Search: running a new query resets the timeline zoom so results render against the full time range (clears any prior visibleStart / visibleEnd)
• Query builder: string-typed fields only offer string-relevant operators (no meaningless numeric comparisons on strings)
• Query builder: changing the selected field preserves the value when types stay compatible; incompatible values show validation instead of silently clearing
• Query builder: Message field paths with unknown types show the full operator list again (fixes over-restriction after string operator narrowing)
• Search results: Manage columns stays right-aligned and the Event type column no longer stretches the header layout
• Search query builder: removed a stray line under the active Execution details tab
• Search results: header divider runs continuously across the scrollbar filler cell

Deprecated

• The legacy Starter plan is no longer available to new customers. Existing Starter customers can stay on their current plan or upgrade to Pro for unlimited Basic Seats, Data Search, and the new volume discount tiers — see the pricing blog for details.

🖼️ Image Panel: Overlay Image Topics​

The Image panel now supports overlay image topics, letting you layer segmentation masks, depth maps, or other image data directly on top of the base camera feed.

🔷 Draco-Compressed Point Clouds​

The 3D panel now renders Draco-compressed foxglove.CompressedPointCloud topics, so you can visualize large point clouds with smaller on-wire payloads. Read more about CompressedPointCloud.

📈 Plot Panel: Seek and Preview From the Chart​

When the Plot panel X-axis type is Message path, hovering a point updates preview time for the player and panels, and clicking a point seeks playback to that time.

📎 MCAP Metadata & Attachments​

The left sidebar adds Metadata and Attachments tabs for MCAP files and cloud recordings, so you can inspect key–value metadata and file attachments without leaving the view.

New & Improved

• Context sidebar tab and data source menu entry show session, event, and recording details without leaving the visualization view

📅 Interactive Timeline​

The Timeline now shows device coverage on a continuous time axis—one row per device—so you can pan and zoom within the range you care about. Hover along a row to see device and time, drag to select a range that stays visible until you dismiss it, and share links that open with your selection already in view.

📈 Plot Panel: Current and Preview Point Indicators​

When the Plot panel X-axis value type is set to Message path, a visual indicator now highlights the points at the current playback time. Hovering over the playback timeline shows a preview indicator at the corresponding data points.

🖼️ GPU-Accelerated Image Decoding​

Raw image decoding in the Image and 3D panels now uses WebGPU for faster performance when available, falling back to software decoding when it isn't. This release also adds NV12 (YUV 4:2:0) support and more accurate colors for common UYVY and YUYV camera formats.

New & Improved

• Gauge, Indicator, Markdown, and State Transitions panels now reject Plot-only time-series message path functions with clear errors; Plot continues to support them

🤖 URDF Joint State Control​

URDF robot models in the 3D panel can now be driven directly by sensor_msgs/JointState or foxglove.JointStates messages, performing forward kinematics within Foxglove. Previously, URDF visualization required publishing tf transforms, which often meant running complex forward kinematics calculations outside the app. See an interactive version in this playground.

🗂️ Sessions​

Sessions let you group recordings from a single device into logical units — a drive, a mission, a field test — so you can organize and visualize data by context rather than by file boundaries. Define custom properties (location, stack version, mission type) to filter and search across sessions, and open a session to load all its recordings as one continuous dataset. See docs, currently available on Team and Enterprise.

🔌 Remote Data Loaders​

Remote Data Loaders connect Foxglove to any queryable data source — internal databases, custom storage systems, or proprietary data lakes — by building a lightweight backend that produces MCAP on demand. The Remote Data Loader handles caching, seeking, and streaming so your team can visualize data directly from where it already lives, without exporting or re-uploading.

⌨️ Embedded Viewer Keybinding API​

The embedded viewer now supports keyboard shortcut customization. Teams embedding Foxglove into review tools or operator dashboards can override or suppress built-in shortcuts that conflict with the host application, and register custom keybindings that notify the parent — enabling keyboard-driven workflows like assigning quality ratings, navigating recording playlists, or controlling playback without leaving the embedded viewer.

🔍 AI-Powered Docs Search​

The documentation site now features AI-powered search. Ask a question in natural language and get a synthesized answer drawn from the docs, alongside traditional keyword results.
