## What does nylas ui do?

The nylas ui command launches a local web-based configuration interface in your browser. Manage connected accounts, view grants, configure settings, and explore CLI features through a graphical dashboard instead of the command line.

## Usage

```bash
nylas ui
```

## Flags

| Flag | Description |
| --- | --- |
| --json | Output as JSON |
| --no-color | Disable color output |
| --verbose(-v) | Enable verbose output |
| --config | Custom config file path |
| --help(-h) | Show help for the command |
| --limit | Limit results (most list commands) |
| --yes(-y) | Skip confirmations |
| --no-browser | Don't open browser automatically |
| --port(-p) | Port to run the server on |

## Examples

The nylas ui command launches a local web-based configuration interface in your browser.

### Launch UI

```bash
nylas ui
```

### Open on a specific port

```bash
nylas ui --port 8080
```

## Example output

```text
Starting Nylas CLI UI...

  Local:   http://localhost:7363

  Opening browser...
  Press Ctrl+C to stop the server.
```

## Troubleshooting

### Browser doesn't open

Copy the URL from terminal output and paste it into your browser. On headless servers, use `--no-browser` if available.

### Port already in use

Another process is using the default port. Try `nylas ui --port 8081` or stop the conflicting process.
