# Open URL in browser

> Open websites in your default browser from the terminal — YouTube, GitHub, Google, and full URLs.

Open sites in your default system browser without leaving the terminal.

## Quick start

```bash theme={null}
arka open youtube
arka open github.com
arka open https://news.ycombinator.com
arka browse google
open google in browser
```

## Site aliases

Common names map to URLs automatically:

| Name                | Opens                                                        |
| ------------------- | ------------------------------------------------------------ |
| `youtube`           | [https://youtube.com](https://youtube.com)                   |
| `google`            | [https://google.com](https://google.com)                     |
| `github`            | [https://github.com](https://github.com)                     |
| `reddit`            | [https://reddit.com](https://reddit.com)                     |
| `wikipedia`         | [https://wikipedia.org](https://wikipedia.org)               |
| `hackernews` / `hn` | [https://news.ycombinator.com](https://news.ycombinator.com) |

Full `https://` URLs and `domain.tld` patterns work as-is.

Arka keeps the path and query you provide. So `open https://example.com/docs?a=1` opens that exact URL instead of inventing a new one.

Natural language examples:

```bash theme={null}
arka open this exact url https://example.com/docs?a=1
arka repair broken links in this file
```

## vs play\_youtube

| Phrase                      | Skill                        |
| --------------------------- | ---------------------------- |
| `arka open youtube`         | Opens youtube.com in browser |
| `arka play lofi on youtube` | YouTube playback skill       |

Arka disambiguates **open** (browser) from **play** / **watch** (media).

## Commands

| Command                     | Description             |
| --------------------------- | ----------------------- |
| `arka open <site-or-url>`   | Open in default browser |
| `arka browse <site-or-url>` | Alias                   |
| `open_url <target>`         | Direct skill (fish)     |
