titty.tools is a fork of cobalt, the open source media downloader. it was made for public benefit: a free, private, and safe way to save media from the internet.

the original cobalt project is great, but its built-in extractors don’t get updated that often, so some sites break or stop working for months. titty.tools fixes that by replacing the whole extraction backend with yt-dlp, which is updated constantly and supports thousands of sites.

yt-dlp backend

instead of one hand-written scraper per site, titty.tools delegates extraction to yt-dlp. that means:

• thousands of supported sites out of the box, not just the big ones;
• sites that break get fixed upstream in yt-dlp, usually within days;
• the server updates its extractor automatically, so nothing stops working while you wait for a release.

remuxing still happens in your browser

downloading a video often means fetching separate video and audio streams and merging them. titty.tools can do that merge locally, in your browser, using WebAssembly ffmpeg (libav). your media never touches the server after the initial link processing.

what’s the same

everything else is inherited from cobalt: the same clean interface, privacy-first defaults, no ads, no trackers, and no account required.

if something doesn’t work, please report it to the titty.tools repository, not the original cobalt one. the original developers don’t maintain this fork’s yt-dlp backend, so they can’t fix its issues.
