- Remove auto-selection of the most recent session on initial load, so the app opens to a blank new-chat page instead of the last session. - Preserve active session state when navigating to/from settings: keep ThreadShell mounted (hidden via CSS) so scroll position, message cache, and streaming state are not lost. - Update onBackToChat to return to blank page when no session was active instead of falling back to the most recent session. - Update related test expectations to match the new navigation behavior.
nanobot webui
The browser front-end for the nanobot gateway. It is built with Vite + React 18 + TypeScript + Tailwind 3 + shadcn/ui, talks to the gateway over the WebSocket multiplex protocol, and reads session metadata from the embedded REST surface on the same port.
For the project overview, install guide, and general docs map, see the root
README.md.
Current status
Note
The standalone WebUI development workflow currently requires a source checkout.
WebUI changes in the GitHub repository may land before they are included in the next packaged release, so source installs and published package versions are not yet guaranteed to move in lockstep.

nanobot/web/dist/ build output served by the gateway
Develop from source
1. Install nanobot from source
From the repository root:
pip install -e .
2. Enable the WebSocket channel
In ~/.nanobot/config.json:
{ "channels": { "websocket": { "enabled": true } } }
3. Start the gateway
In one terminal:
nanobot gateway
4. Start the WebUI dev server
In another terminal:
cd webui
bun install # npm install also works
bun run dev
Then open http://127.0.0.1:5173.
By default, the dev server proxies /api, /webui, /auth, and WebSocket
traffic to http://127.0.0.1:8765.
If your gateway listens on a non-default port, point the dev server at it:
NANOBOT_API_URL=http://127.0.0.1:9000 bun run dev
Access from another device (LAN)
To use the webui from another device on the same network, set host to "0.0.0.0" and configure a token or tokenIssueSecret in ~/.nanobot/config.json:
{
"channels": {
"websocket": {
"enabled": true,
"host": "0.0.0.0",
"port": 8765,
"tokenIssueSecret": "your-secret-here"
}
}
}
The gateway will refuse to start if host is "0.0.0.0" and neither token nor tokenIssueSecret is set.
Then open http://<your-ip>:8765 on the other device. The webui will show an authentication form where you enter the secret. It is saved in your browser so you only need to enter it once.
Build for packaged runtime
cd webui
bun run build
This writes the production assets to ../nanobot/web/dist, which is the
directory served by nanobot gateway and bundled into the Python wheel.
If you are cutting a release, run the build before packaging so the published wheel contains the current WebUI assets.
Test
cd webui
bun run test
