## Built-in Fetchers

FetchKit routes each request through an ordered fetcher registry. Specialized
fetchers match first; the default fetcher handles everything else.

- `GitHubCodeFetcher` - GitHub source file URLs (`/blob/...`)
- `GitHubIssueFetcher` - GitHub issue and pull request URLs
- `GitHubRepoFetcher` - GitHub repository home pages
- `TwitterFetcher` - X/Twitter status URLs
- `StackOverflowFetcher` - Stack Overflow and Stack Exchange question URLs
- `PackageRegistryFetcher` - PyPI, crates.io, and npm package pages
- `WikipediaFetcher` - Wikipedia article URLs
- `YouTubeFetcher` - YouTube watch and `youtu.be` URLs
- `ArXivFetcher` - arXiv abstract and PDF URLs
- `HackerNewsFetcher` - Hacker News item threads
- `RSSFeedFetcher` - RSS and Atom feed URLs
- `DocsSiteFetcher` - docs sites with `llms.txt`/`llms-full.txt` support
- `DefaultFetcher` - all remaining HTTP/HTTPS URLs with HTML conversion, streaming, timeout handling, and binary detection
