Bitmagnet is a self-hosted BitTorrent indexer, DHT crawler, and torrent search engine that allows users to search and index torrents without relying on external trackers or indexers. The project is currently in alpha and features a DHT crawler, content classifier, and GraphQL API. The DHT crawler works by requesting metadata about each info hash it discovers, which is then further enriched by attempting to classify it and associate it with known pieces of content. This approach allows Bitmagnet to build an index of everything shared on BitTorrent over time.
