cobalt is a social media downloader with zero bullshit. It's friendly, accessible, efficient, and doesn't bother you with shock ads or privacy invasion "consent" popups.

cobalt is written with Node.js technologies and uses Express.js framework to run a server side app to capture and download the media.

It preserves original media quality, so you get the best downloads possible (unless you change that in settings).
