Open the app in a browser tab
Serve the whole Hivemind app to a browser tab on this computer, or to another device through Tailscale.
Use Hivemind in a browser tab: the whole app, with your terminals and agents. It listens on this computer only, unless you put it behind Tailscale.
Paste this into your coding agent to turn on the browser tab and check it answers.
Show the prompt
Turn on Hivemind's "Serve the app to a browser" and check it answers, on this computer only.
1. Check the Hivemind app is running: `hive ctl agents --json` must not fail with exit code 3.
2. Turn it on: `hive config set browserApp.enabled true`. The port is `browserApp.port` (4483 by default): read it with `hive config get browserApp`.
3. Check something answers: `curl -sS -o /dev/null -w '%{http_code}' http://127.0.0.1:4483/`, with the port from step 2.
4. The link with its key is shown only in the app. Tell me to open Settings → In a browser and press Open. Never print, copy or send that link anywhere: whoever has it can use my terminals.
At the end, tell me how to turn it off: the switch in Settings → In a browser, or `hive config set browserApp.enabled false`.
REFERENCE https://hivemind.griiken.com/guide/browser-tab.mdThe link carries a key. Anyone with the link can use your terminals. Do not share it.
Turn it on
- Open Settings → In a browser.
- Turn on Serve the app to a browser.
- Press Open next to the link that appears.
Check: the app opens in a browser tab at http://127.0.0.1:4483/#token=….
The key in the link changes each time the app starts. Open the new link after a restart.
Reach it from another device
- Put the app behind Tailscale on this computer: run
tailscale servefor port 4483. - In Settings → In a browser, open More options.
- Under Other names, add the address Tailscale gives, with its port if it has one.
Check: a second link appears, with that address. Open it on the other device.
Port, under More options, changes the port from 4483.
If it didn't
| You see | Do |
|---|---|
Port 4483 is in use by another program | Pick another Port under More options. |
| The old link stopped working | The app restarted, so the key changed. Use the new link. |
