forum-archive
Desuarchive (4chan archive)
A FoolFuuka-based archive of selected 4chan boards (/a/, /int/, /k/, /tg/, /wsg/ and others) with a large history. It keeps full-text-searchable copies of threads, so you can find old 4chan posts after they vanish from 4chan itself, either on the website or through its keyless JSON API. A core source for forum research on the boards it covers; note that some boards carry NSFW or extreme content.
Why it’s useful & how it works
Keyless FoolFuuka JSON; direct IP errored, proxy works. Same API shape as 4plebs (shared client logic). NSFW/extreme content — neutral OSINT note.
What’s inside
Many boards, large history.
