cobalt

cobalt is a media downloader designed to be simple and unobtrusive: paste a link, get the file. According to its README, it has no ads, trackers, or paywalls, and it never caches content, instead working like a proxy for public media. The project is organized as a monorepo containing the source code for the API, the web frontend, and related packages. Documentation covers how to run a cobalt instance, how to protect an instance, API environment variables, and the API itself. The README states that cobalt is intended only for free and publicly accessible content, takes zero liability for how downloaded content is used, and is not a piracy tool. Licensing is split: the API and web directories have their own licensing information, while the rest of the repository is under AGPL-3.0 unless otherwise specified. The project is sponsored by royalehosting.net, which hosts part of its infrastructure.
