cobalt

Sleek and easy to use social media downloader built on JavaScript. Try it out live: co.wukko.me!

What is cobalt?

Everyone is annoyed by the mess video downloaders are on the web, and cobalt aims to be the ultimate social media downloader, that is efficient, pretty, and doesn't bother you with ads or privacy invasion agreement popups.

cobalt doesn't remux any videos, so you get videos of max quality available (unless you change that in settings).

What's supported?

• Twitter
• YouTube and YouTube Music
• bilibili.com
• Reddit
• VK

What still has to be done

• Quality switching for bilibili and Twitter
• Clean up the mess that localisation is right now
  • Sort contents of .json files
  • Rename each entry key to be less linked to specific service (entries like youtubeBroke are awful, I'm sorry)
• Add support for more languages when localisation clean up is done
• Use esmbuild to minify frontend css and js
• Make switch buttons in settings selectable with keyboard
• Do something about changelog because the way it is right now is not really great
• Remake page rendering module to be more versatile
• Matching could be redone, I'll see what I can do
• Facebook and Instagram support
• TikTok support (?)
• Support for bilibili.tv (?)
