If I can get a proper static copy of MDN, I’ll make a torrent and share a magnet link here. I know I’m not the only one who wants something like this. I don’t think the file sizes will be so bad. My current “build” of the entire site is sitting at 1.36 GiB. (Only a little more than double the size of node_modules!) So, with browser compatibility data and such, I think it’ll still be less than 2GiB.

Aggressively compressed with bzip2 -9, it’s only 114.29 MiB. A compression ratio of 0.08. That blows my mind.
