About 4ChanSearch
4ChanSearch is an independent search tool for 4chan. It is not affiliated with, endorsed by or run by 4chan.
What is indexed
- 53 boards - only boards that 4chan itself classes as worksafe. NSFW boards and /pol/ are never indexed.
- Text only. Thread subjects and the first 300 characters of each opening post. No images, thumbnails or files are downloaded or stored.
- Live threads only. When a thread leaves 4chan it leaves this index at the next refresh.
- Threads containing certain keywords are filtered out of results entirely.
How it is collected
Every 10 minutes we read each board's catalog from 4chan's public, read-only JSON API, following 4chan's published API rules (no more than one request per second, conditional requests so unchanged boards are not re-downloaded). Archive coverage comes from the community-maintained archives.json list. Uptime is measured by our own automatic checks.
Report a result
If a result links to something illegal or harmful, or you want something removed, email contact@4chansearch.org with the link. We review every report and can block a thread or keyword from the index permanently. Content itself lives on 4chan or the archives, so please report it to them too.
