ffmpeg

cobalt heavily relies on ffmpeg for converting and merging media files. it's an absolutely amazing piece of software offered for anyone for free, yet doesn't receive as much credit as it should.

you can support ffmpeg here!

ffmpeg-static

we use ffmpeg-static to get binaries for ffmpeg depending on the platform.

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

youtube.js

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