🔑 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
  • State Transitions: a Label position setting shows series labels in a column to the left or right of their rows — see Label position

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
Fixes
  • Playback: pausing a cloud recording keeps its data stream, so resuming doesn't buffer again
  • Playback: device-stream links stay at the linked time instead of jumping back to the start of the range
  • Playback: timestamps in the America/Vancouver time zone show UTC-7 after British Columbia moves to permanent UTC-7 on November 1, 2026

Foxlet v1.7.1

Foxlet​

This release stops trusting compromised eMudhra certificate authorities, and fixes retention for recordings indexed by Foxlet before v1.3.0 and recordings with no device name.

Security
  • Foxlet no longer trusts certificates issued by compromised eMudhra certificate authorities.
Fixed
  • Retention now deletes files left behind for recordings indexed by Foxlet before v1.3.0. See Delete recording files.
  • Deletion no longer fails when a recording has a device ID but no device name.

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

Primary Site v0.0.109

This release improves import reliability on index-in-place sites, fixes playback and export failures, speeds up file deletion, and stops trusting certificates from compromised eMudhra certificate authorities.

Changed
  • queryService.deployment.enableBetaStreamExecutor no longer has any effect. All playback uses the faster streaming mode enabled by default in v0.0.108, and you can no longer switch back to the previous mode. You can remove the setting from your values.yaml.
  • The time_to_first_byte_ms and stream_duration_ms query service metrics now measure the whole request, including authorization and request setup. Expect higher values after upgrading, and adjust any dashboards or alerts built on these metrics. See Query service metrics.
Fixed
  • On index-in-place sites, files that cannot be indexed because of a permanent problem, such as a corrupt or unsupported file, are now quarantined. Previously they were retried indefinitely. See Quarantined files.
  • On index-in-place sites, quarantined files can now be downloaded. Previously the download failed.
  • Deleting a file from an index-in-place bucket now removes its recording from Foxglove even when the site cannot list the bucket. Previously, AWS buckets without s3:ListBucket permission kept deleted recordings visible indefinitely.
  • Playback no longer fails for JSON messages that contain null values in an array.
  • Exporting a recording as a ROS 1 bag no longer produces a file the Foxglove CLI rejects.
  • When an inbox listener pod is stopped, such as during an upgrade or scale-down, it now finishes the imports it is processing before it exits.
Performance
  • Deleting recordings and cleaning up temporary files is faster on sites with many files.
Security
  • Primary site services no longer trust certificates issued by compromised eMudhra certificate authorities.

Remote Data Loader v0.0.12

Stream timing metrics now include the whole request, and the remote data loader no longer trusts certificates from compromised eMudhra certificate authorities.

Changed
  • The time_to_first_byte_ms and stream duration_ms metrics now measure the whole request, including authorization and the manifest request. Expect higher values after upgrading, and adjust any dashboards or alerts built on these metrics.
Security
  • The remote data loader no longer trusts certificates issued by compromised eMudhra certificate authorities. This applies to connections to your manifest endpoint and data sources.

Foxlet v1.7.0

Foxlet​

This release keeps auto-import recordings, and recordings requested for import, on the device until they upload.

New & Improved
  • Added the recordings_retained_pending_upload and recordings_retained_pending_upload_bytes Prometheus metrics, which count recordings that Foxlet keeps past the retention period because their upload has not succeeded.
Fixed
  • Auto-delete local files after age no longer deletes an auto-import recording, or a recording requested for import, before its upload succeeds. Previously, a device that was offline for longer than the retention period could delete these recordings before uploading them. See Delete recording files.
  • Foxlet now exits, instead of retrying an upload every second, when Foxglove rejects the upload because the device's recording state is out of date. See Error: "terminating due to invalid agent epoch".

Foxglove 3.4.0

📈 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.

New & Improved

  • Plot: exporting XY data as CSV finishes when an enabled series has no data
  • Plot: CSV export keeps rows with CJK and other 3-byte UTF-8 labels intact, and works for plots with a custom x-axis and long expressions
  • Plot: a stray point and flat line no longer appear in timestamp plots after a live source's clock resets to an earlier time
  • Plot: in comparison mode, series expression autocomplete suggests fields from the source the panel is pinned to, or from every loaded source when comparing all

Foxlet v1.6.0

Foxlet​

This release improves the reliability of recording tracking and auto-delete, and reduces CPU usage.

New & Improved
  • Reduced CPU usage when indexing and submitting recordings.
  • Added the recordings_deletion_retained Prometheus metric, which counts recordings that are pending deletion because Foxlet could not remove the local file.
  • Added startup validation for storage paths. The error message includes the path that failed.
  • Updated the Docker image to Alpine 3.24.2 and OpenSSL 3.5.8.
Fixed
  • Changing only a recording file's metadata (for example, its permissions) no longer causes it to be re-imported as a new recording.
  • Recordings are no longer reported as deleted until their local file is gone. Files that could not be removed are retried periodically instead of being re-imported.
  • Changing or disabling the retention period no longer leaves recordings stuck pending deletion.
  • Recordings are no longer marked as removed after a filesystem scan that was interrupted by I/O errors, or when the file is still on disk but no longer matches the recording filters.
  • Reporting new recordings to Foxglove no longer stalls when every recording in a batch is rejected.
  • Requests to Foxglove are retried when a response is cut off mid-transfer.
  • Foxlet now shuts down promptly during a filesystem scan.

Foxglove 3.3.0

🗂 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.

🔎 Filter list pages with chips​

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.
