looking for a specific downloader website

hi all, i saw a post (or perhaps it was in the comments) about 1-2 weeks ago of a website to download any youtube/vimeo/instagram/tiktok/whatever video/audio in many different formats. it was a FOSS website. dark background, with maybe red text in places? on mobile, it had tabs on the bottom for video/audio/other.

i tried searching for it for a while now with no success. was hoping someone here mightve seen it too and bookmarked it..

i remember finding it via a lemmy post or comment.

if anyone can help me out its greatly appreciated!

thanks yall <3
