4Plebs

4plebs is a community-run archive that preserves threads and images from selected boards on 4chan. Since 2013, the site has automatically collected content from boards covering topics such as advice, flash, high-resolution images, automobiles, politics, sports, traditional games, travel, television and film, and paranormal subjects. Its stated aim is to preserve this material for future generations.

Visitors can browse dynamic board pages and complete archived threads, or use search tools to find posts and images across the available archives. Search options include filters for details such as board, subject, username, date, file type, image dimensions, and post status. The site also provides a live JSON API for developers, along with an API reference, FAQ, credits, legal information, transparency details, and data dumps. 4plebs reports more than 38 terabytes of active data and over one billion posts and threads. The site describes itself as unofficial and unaffiliated with 4chan, and is powered by FoolFuuka and Asagi.
