🎨 Set URDF opacity and toggle outlines​

You can now adjust the opacity of URDF models and toggle their outlines in the 3D panel. This gives you more control over how your robot models are displayed.

🔍 Marquee zoom for Plot and State Transitions panels​

The Plot and State Transitions panels now support marquee zooming. Click and drag to select an area to zoom into.

⌨️ Keyboard shortcuts on desktop​

The desktop app now supports keyboard shortcuts for common actions:

🥳 Initial public release of the Foxglove SDK​

We're excited to introduce the Foxglove SDK, a unified toolkit that simplifies integrating your robotics stack with Foxglove. The SDK provides a single, idiomatic API for live visualization, logging, and remote monitoring.

Today, we're releasing the initial version of the Foxglove SDK for C++, Python, and Rust. Built on a shared Rust core, it ensures consistency and reduces feature drift. You can:

• Log structured data to MCAP files for offline analysis
• Stream live data to Foxglove via the WebSocket protocol
• Use high-level logging APIs for common Foxglove schemas like CompressedImage and SceneUpdate
• Define and log custom message types with minimal boilerplate
• Switch between live streaming and file logging using the same instrumentation

Get started​

Get started in a few lines using the SDK to log your data to MCAP files, stream live data directly to the Foxglove app, or both simultaneously:

import foxglove as fg
from foxglove.schemas import Pose, PoseInFrame, Quaternion, Timestamp, Vector3

fg.start_server()

with fg.open_mcap("foo.mcap"):
    fg.log("/example", PoseInFrame(
        timestamp=Timestamp(sec=0),
        frame_id="ego",
        pose=Pose(
            position=Vector3(x=1.0, y=2.0, z=3.0),
            orientation=Quaternion(x=0.0, y=0.0, z=0.0, w=1.0),
        ),
    ))

Key features​

The Foxglove SDK addresses challenges in integrating custom robotics frameworks and tooling:

• Unified Logging Interface: Record to disk or stream live data using a consistent API
• High-Level and Low-Level APIs: Choose between high-level APIs for common schemas or low-level APIs for custom serialization
• Live Visualization Support: Stream live data to Foxglove for real-time visualization
• Cross-Language Consistency: Shared Rust core ensures consistent behavior across Rust, Python, and C++

Brand update​

Introducing the new Foxglove brand.

📮 Plot by any timestamp​

You can now generate plots and state transitions using arbitrary timestamp fields from your messages. This gives you more flexibility in how you visualize your time-series data.

👨‍💼Layout Manager​

We've introduced a dedicated page for managing your Foxglove layouts. The new layout manager makes it easier to organize, share, and maintain your visualization configurations.

🧊 Point cloud cube mode​

Point clouds and laser scans now support a cube rendering mode that displays points as cubes. This is useful when your point cloud data semantically represents voxels.

🚢 Performant API for visualizing data across a time range​

The subscribeMessageRange extension API is now generally available. Using this API, Foxglove can load data in small chunks and cache only a subset of serialized data. By doing this, heap memory usage is reduced while still allowing fast re-reads. As a result, panels can display larger datasets without exhausting memory resources.

The subscribeMessageRange API should be used instead of preload: true and context.watch("allFrames") in order to load data across a data source. These previous APIs are now deprecated.

The reference documentation for the extension API is also now available in the core Foxglove documentation.

⏮️ Quick navigation to recent layouts​

The layout menu now shows a list of recently used layouts at the top for quick navigation.

📐 Locked axis scales in the Plot panel​

The Plot panel now supports locking the x- and y-axis scales to a 1:1 ratio. This can be set via the "Axis scales" drop down in the panel settings.

🩻 Preview topics before importing with Foxglove Agent​

The Foxglove Agent tracks metadata about what topics exist in each MCAP recording and forwards this information to the Foxglove Cloud. We now make this topic-level information available for you to inspect directly in Foxglove before importing the recording.

Learn more about the Foxglove Agent in the Agent docs or by watching the recording of our Foxglove Agent live demo.
