+Start a new session in Goose Web, a lightweight web-based interface launched via the CLI that mirrors the desktop app's chat experience.
+
+Goose Web is particularly useful when:
+- You want to access Goose with a graphical interface without installing the desktop app
+- You need to use Goose from different devices, including mobile
+- You're working in an environment where installing desktop apps isn't practical
+
+**Usage:**
+```bash
+goose web
+```
+
+**Options:**
+- **`-p, --port <PORT>`**: Port number to run the web server on. Default is `3000`.
+- **`--host <HOST>`**: Host to bind the web server to. Default is `127.0.0.1`.
+- **`--open`**: Automatically open the browser when the server starts.
+
+**Examples:**
+```bash
+# Start web interface at `http://127.0.0.1:3000` and open the browser
+goose web --open
+
+# Start web interface at `http://127.0.0.1:8080` 
+goose web --port 8080
+
+# Start web interface accessible from local network at `http://192.168.1.7:8080`
+goose web --host 192.168.1.7 --port 8080
+```
+
+**Limitations:**
+
+While the web interface provides most core features, be aware of these limitations:
+- Some file system operations may require additional confirmation
+- Extension management must be done through the CLI
+- Certain tool interactions might need extra setup
+- Configuration changes require a server restart
+
+:::warning
+Don't expose the web interface to the internet without proper security measures.
+:::
+
+:::info
+Use `Ctrl-C` to stop the server.
