# Supported sites

Below is a list of all extractors that are currently included with yt-dlp.
If a site is not listed here, it might still be supported by yt-dlp's embed extraction or generic extractor.
Not all sites listed here are guaranteed to work; websites are constantly changing and sometimes this breaks yt-dlp's support for them.
The only reliable way to check if a site is supported is to try it.
