Install the desktop app

The Nori desktop app bundles everything needed to talk to robot hardware — no Python, no terminal, no pip. Download it, drag it in, open it.

Status

The desktop app is not yet published. The Tauri shell and the frozen backend both build, but no signed installer has shipped on any OS. Until it does, run from source (below). Track this in desktop/HANDOFF.md.

Download

🚧 To write

Download links per platform, once installers ship:

Platform	File	Notes
macOS (Apple Silicon)	Nori Lab.dmg	Notarized — no Gatekeeper warning.
Windows	Nori Lab.exe	NSIS installer, signed.
Linux	Nori Lab.AppImage	chmod +x, then run.

Also cover: what the OS scare screen looks like if a build isn't signed yet, and how to get past it deliberately.

What the app actually does when it starts

Worth knowing, because most "the app won't open" reports are one of these steps failing:

1. It spawns a frozen Python backend bundled inside the app, which serves the API and UI on 127.0.0.1:8000.
2. It waits for that port to answer (up to 60 s).
3. It opens a window pointing at it.

So the app is a local web app in a native window. If port 8000 is already in use by something else, that's a problem — see Desktop app troubleshooting.

Run from source (until installers ship)

Requires Python ≥ 3.12 and Node.

git clone https://github.com/nori-robotics/NoriLeLab
cd NoriLeLab
pip install -e .
lelab            # serves API + UI on :8000 and opens a browser

For frontend development, lelab --dev runs Vite on :8080 against a reloading backend on :8000.

🚧 To write

• System requirements (RAM, disk — the bundle is ~770 MB on disk because torch ships in it so inference never depends on Wi-Fi).
• Updating: how the app checks for and applies a new version.
• Uninstall, and what's left behind (~/.cache/huggingface/lerobot/ holds calibration, saved ports, and config selections).
