# Browser Testing with cmux browser
Test websites and frontend tools using `cmux browser`.
## First Step
Run the help command to discover all available commands:
```bash
cmux browser --help
```
## Determining the Target URL
Use the URL appropriate for the current context:
- **Local dev server**: Check the project for its dev server port (commonly `http://127.0.0.1:8000` or similar)
- **Remote site**: Use the URL provided by the user or documented in the project
## Key Context
- `cmux browser open <url>` returns a surface handle (e.g. `surface:14`) — use it for all subsequent commands
- Element refs (e.g. `e9`, `e18`) come from `snapshot --interactive` and **change after page mutations** — always re-snapshot before interacting
- When `click ref=eNN` fails with JS errors, fall back to `eval "document.querySelector('...').click()"`
- For large text input, use `eval` with JS instead of `fill`/`type`
