this directory includes the source code for cobalt api. it's made with express.js and love!

if you want to run your own instance for whatever purpose, follow this guide. we recommend to use docker compose unless you intend to run cobalt for developing/debugging purposes.

there is currently no publicly available pre-hosted api. we recommend deploying your own instance if you wish to use the cobalt api.

you can read the api documentation here.

this list is not final and keeps expanding over time! if the desired service isn't supported yet, feel free to create an appropriate issue (or a pull request 👀).

cobalt api code is licensed under AGPL-3.0.

this license allows you to modify, distribute and use the code for any purpose as long as you:

• give appropriate credit to the original repo when using or modifying any parts of the code,
• provide a link to the license and indicate if changes to the code were made, and
• release the code under the same license

cobalt relies on ffmpeg for muxing and encoding media files. ffmpeg is absolutely spectacular and we're privileged to have the ability to use it for free, just like anyone else. we believe it should be way more recognized.

you can support ffmpeg here!

cobalt relies on youtube.js for interacting with youtube's innertube api, it wouldn't have been possible without this package.

you can support the developer via various methods listed on their github page! (linked above)

cobalt-api also depends on:

• content-disposition-header to simplify the provision of content-disposition headers.
• cors to manage cross-origin resource sharing within expressjs.
• dotenv to load environment variables from the .env file.
• express as the backbone of cobalt servers.
• express-rate-limit to rate limit api endpoints.
• ffmpeg-static to get binaries for ffmpeg depending on the platform.
• hls-parser to parse HLS playlists according to spec (very impressive stuff).
• ipaddr.js to parse ip addresses (used for rate limiting).
• nanoid to generate unique identifiers for each requested tunnel.
• set-cookie-parser to parse cookies that cobalt receives from certain services.
• undici for making http requests.
• url-pattern to match provided links with supported patterns.
• zod to lock down the api request schema.
• @datastructures-js/priority-queue for sorting stream caches for future clean up (without redis).
• @imput/psl as the domain name parser, our fork of psl.

...and many other packages that these packages rely on.
