Styri

The ROS 2 web dashboard and operator panel that never leaves your network.

Built for the operators running robots on site, not a cloud dashboard miles away. Open-source ROS 2 operator panel that runs on the robot or any Linux box on its network and works in any browser on the LAN. Fully offline, free from the first robot. One command to start.

Quickstart

Run it on any ROS 2 machine (Humble or Jazzy, amd64 or arm64):

docker run --rm --network host ghcr.io/styri-dev/styri-core:v0.3.0

Open http://localhost:8080. Styri finds your robot's topics over DDS and shows them live.

Host networking lets Styri see DDS discovery on your LAN. Open source: read the code before you run it.

On a Mac? Run Styri on the robot or any Linux machine on its network, and open the panel from any browser, Mac included. Docker on macOS can't see a robot on another machine, but docker compose up (below) gives you the full demo with a simulated robot.

No robot handy? Run the simulated robot and the panel together:

docker compose up

What you get

• Overview — robot status, battery, voltage, CPU temperature and link health, readable at a glance on a touchscreen
• Topics — every discovered topic with its rate and last-message age
• Activity log — a local log of connections, warnings and state changes, exportable to CSV
• Honest data — every value shows when it goes stale; disconnects are obvious

Styri Core is read-only: it never publishes to your robot. Controls are on the roadmap.

Nothing phones home

• Every asset is served locally: fonts, icons, scripts. No CDN.
• No telemetry, no license server, no account.
• Unplug the internet and it still works.

Verify it yourself:

sudo tcpdump -i any 'not net 10.0.0.0/8 and not net 172.16.0.0/12 and not net 192.168.0.0/16 and not host 127.0.0.1 and not net 224.0.0.0/4'

Nothing should appear while Styri runs. (DDS discovery uses LAN multicast, 224.0.0.0/4, which never leaves your network.)

Foxglove in the lab. Formant in the cloud. Styri on the floor.

	RViz2	Foxglove	Formant	Styri
Built for	Engineers	Engineers: data visualization and log analysis	Fleet operations teams, remotely from the cloud	Operators running robots on site
Runs in	Desktop / X11 on the robot or forwarded	Desktop app on each machine	Cloud web app; self-hosted on your own servers for restricted sites	Any browser on the robot's local network
Offline use	Fully local	Free and Pro: account sign-in needs internet. Fully offline via standalone license or on-prem deployment on Enterprise	Standard: agent streams to Formant's cloud; teleop needs Formant and Twilio servers. Air-gapped only via self-hosted on-prem deployment	Fully offline on every tier, including free

Foxglove helps engineers analyze robot data. Formant runs fleets from the cloud. Styri helps operators run robots on site — fully offline, from the free tier up.

How it works

ROS 2 nodes ──DDS──▶ Styri bridge ──local WebSocket──▶ Styri panel ──LAN──▶ any browser
                         │
                         └──▶ local activity log (SQLite)

One container: a small bridge subscribes to your ROS 2 topics and serves a static web panel. Nothing leaves the machine except to browsers on your LAN.

Configuration

Pass settings as environment variables, for example docker run -e ROS_DOMAIN_ID=7 -e STYRI_MIN_VOLTAGE=23.0 --rm --network host ghcr.io/styri-dev/styri-core:v0.3.0.

Variable	Default
ROS_DOMAIN_ID	0	Must match the robot
STYRI_ROBOT_NAME	the host name	Shown in the header
STYRI_BATTERY_TOPIC	/battery_state	A sensor_msgs/BatteryState topic
STYRI_DIAGNOSTICS_TOPIC	/diagnostics	A diagnostic_msgs/DiagnosticArray topic
STYRI_MIN_VOLTAGE	unset	Volts. Below this the Voltage tile turns amber and the status shows a low-voltage warning, whatever the charge reads. Unset, voltage is shown but never judged.

Map your robot's topics

Different topic names, another message type, the robot's own status, or a few values of your own? Describe them in one styri.yaml and mount it:

robot: {name: amr-01, namespace: /robot1}
battery: {topic: battery, percentage: charge, percentage_scale: 1, warn_below: 30}
status: {topic: mode, field: data, fault: [ERROR, ESTOP]}
fields:
  - {label: Motor current, topic: motor/current, field: data, unit: A, warn_above: 12}

docker run --rm --network host -v "$PWD/styri.yaml:/etc/styri/styri.yaml:ro" ghcr.io/styri-dev/styri-core:v0.3.0 styri check

styri check tests the file against the live robot and names anything it can't find, with close matches. Presets for TurtleBot 4 and generic BatteryState robots ship in the image. The full reference: docs/MAPPING.md.

Roadmap

• Controls — software stop, hold-to-drive teleop and waypoint dispatch, with sign-in and roles. A software stop never replaces the robot's hardware E-stop.
• Fleet view — many robots, one screen.
• Air-gapped delivery — signed offline install package, SBOM and compliance audit exports.
