# Bolt Web UI

> bolt web serves a browser-based UI on top of a running Bolt server — useful for shared team boxes, remote machines, and anywhere a TUI isn't practical.

`bolt web` starts a Bolt server and serves a browser UI in front of it. It's the same engine as the TUI, just rendered in a browser tab.

## Start it

```bash theme={null}
bolt web                                # localhost only
bolt web --hostname 0.0.0.0 --port 4096
```

Then open the printed URL. When exposing over a network, set basic auth first:

```bash theme={null}
export BOLT_SERVER_USERNAME=teamname
export BOLT_SERVER_PASSWORD=$(openssl rand -hex 24)
bolt web --hostname 0.0.0.0 --port 4096
```

## When to use the web UI

* Running Bolt on a beefy remote machine but driving it from a laptop.
* Sharing a live session with a teammate for pair-debugging.
* Environments where a full TUI is awkward (Chromebooks, tablets, coworking machines).

* [Remote Sessions](/server/remote-sessions) — attach a TUI to the same server the web UI serves.
