🤏 Customize table views

You can now manage and resize table columns on the Device and Event tables to customize how you view your data.

⏱️ RFC 3339 and 24-hour time formats

Visualization playback now supports displaying timestamps in RFC 3339 (ISO 8601) and 24-hour formats in addition to 12-hour and epoch.

✍️ Renamed NPM package

When we launched Foxglove 2.0, we dropped the "Studio" name. In keeping with that, we renamed the @foxglove/studio NPM package to @foxglove/extension. Please update your custom extensions to depend on @foxglove/extension to receive future SDK updates.

📞 Better ROS Service call integration

We’ve improved the Foxglove client integration with ROS Services to allow Foxglove to be aware if a service is unavailable and the service has failed. The Foxglove websocket protocol now has a serviceCallFailure operation that can communicate to custom panels or the Foxglove Service Call panel when a call fails.

📈 Resizable reference lines in the Plot panel

Did you know you can create reference lines in the Plot panel? Now you can adjust the size of reference lines to improve their visibility.

📹 Low-latency multi-video playback

Buckle up for smoother video loading: We've made performance improvements to video playback so you get a low latency experience when visualizing multiple CompressedVideo topics at once.

Have you ever wanted to get a 3D view of the entire world? One of our users did, but had some issues with z-fighting that kept the visualization within Foxglove from looking as sharp as it should. We think that outer-space fighting should be limited to intergalactic battles, so we added a new setting to enable a logarithmic depth buffer, which can improve rendering precision for large distance scales.

Using this feature may lead to a loss in rendering performance, but may be worth the price for users looking to visualize Earth-scale data, large maps, or just wanting to zoom in/out really, really far.

In this example below:

  • The left pane does not use logarithmic depth, and it has a near clipping plane of 1.0. The grids render smoothly, but objects close to the viewer are clipped.
  • The middle pane does not use logarithmic depth, and has a near plane of 0.01. The viewer can get closer to objects without clipping, but rendering artifacts (z-fighting) appear between multiple grids.
  • The right pane enables the new logarithmic depth setting. This avoids z-fighting by providing more depth precision for the grids, while still allowing a near plane value of 0.01 for reduced clipping.


The Service Call panel now has an option to hide the request and response text fields. This allows you to configure a request once up front, then invoke the service call without any distractions. We love distractions, but only the kinds that have wet noses and wagging tails.


JSON data sources

  • When using a WebSocket connection, JSON channels and services with no schema are now supported (using an empty string for the schema name and data).
  • Added support for fixed-length arrays (specified with prefixItems).

Stability and usability

  • The web application no longer encounters errors when a new version is released while the app is already open.
  • Various usability enhancements to Recordings, General and Team settings, Webhooks, data playback while buffering, and deep linking.
  • Improvements to error messages for opening incompatible files and layouts, and for WebSocket connections that encounter unexpected server behavior.

User scripts

  • Improvements to user scripts to allow returning types that consist of  fields or fields with types:
type Output = {
field1: Message<"std_msgs/String">;
field2: Array<number>;

It is now possible to create elaborate return types, for example:

import { Input, Message, Time } from "./types";
import { subtractTimes } from "./time";

type InputType = Message<"geometry_msgs/PoseStamped">;
type Output = {
header: InputType["header"];
time_diff: Time;
translation: Message<"geometry_msgs/Vector3">;
random_array: Array<number>;

export const inputs = ["/pose_stamped"];
export const output = "/pose_difference";

let lastMessage: InputType | undefined;

// Calculates translation & time difference between two subsequent poses.
export default function script(
event: Input<"/pose_stamped">,
): Output | undefined {
const message = event.message;

if (!lastMessage) {
lastMessage = message;
return undefined;

const output: Output = {
header: message.header,
time_diff: subtractTimes(message.header.stamp, lastMessage.header.stamp),
translation: {
x: message.pose.position.x - lastMessage.pose.position.x,
y: message.pose.position.y - lastMessage.pose.position.y,
z: message.pose.position.z - lastMessage.pose.position.z,
random_array: [Math.random(), Math.random()],

lastMessage = message;
return output;

Snap package

  • Added interface to support using Foxglove with gamepads via the Snap Store.


  • Playback performance improvements when buffering data.

Downloads: Linux: deb amd64 arm64, snap amd64 | Windows: Universal | Mac: Universal


For more information, see our Foxglove 2.0 Announcement.

Smoother navigation

  • You can now visualize your data and manage your Devices, Recordings, and Events all in the same app. This new workflow is available both in the desktop app and at Click the Foxglove logo to access the new navigation from the visualization screen:

  • When opening the app, you will now be greeted with the Dashboard. The “Open local file”, “Open connection”, “Recently viewed”, and “Explore sample data” features are now part of the Dashboard.

Performance improvements

  • We’ve made performance improvements across plots, user scripts, 3D models, H.264 video, and general playback.
  • Fixed an issue where Windows 11 would put the app into “efficiency mode”, degrading app performance.

More panel actions

  • The panel actions overlay now has separate buttons to split right and split down, rather than a single split button that chooses a split direction automatically. Hold the backtick (`) key and hover over a panel to access the quick actions:

Playback and data sources

  • The playback speed setting is no longer saved per-layout; instead, the setting will persist for an individual user/browser.
  • Topics using OMG IDL schemas now support optional member fields on mutable structs.
  • Fixed an issue with loading glTF models via package:// URLs over a WebSocket connection.
  • The “Message rate” setting has been removed. Adjusting this setting did not always have the intended effect, and the application already adapts dynamically to system performance.


  • The Plot panel now displays more information about series errors and warnings in the legend.

  • Fixed some visual alignment issues in Plot and State Transitions.


  • Fixed an issue in the 3D panel where the scene would not exactly track the mouse while panning in 2D mode.


  • The Log panel now supports Message Converters with a toSchemaName that matches one of the panel’s supported schemas.


  • Fixed a bug that caused a message converters to be run on allFrames when they should not have been.
