# Supported sites

Below is a list of all extractors that are currently part of yt-dlp.
If a site is not listed here, it might still be supported by yt-dlp due to embed extraction or the generic extractor.
Not all sites listed here are guaranteed to work. If websites change the extractor might stop working.
The only reliable way to check if a site is supported is to try it.
