Self-hosted, high-performance BitTorrent DHT crawler and content indexer. Drop it into your *arr stack as a Torznab-compatible indexer and let the public DHT fill the gaps your private trackers miss.

MIT-licensed. No telemetry. No accounts. Just an indexer you own.

VPN strongly recommended — DHT participation exposes your node's IP to the swarm. See Legal / Disclaimer for the full network-isolation and liability notice.

Feature highlights

  • DHT crawling -- Full BEP-5/9/10/33/42/43/51 compliance for broad, resilient peer discovery
  • CEL-based classifier with optional LLM rerank -- Rule-driven content classification that can escalate ambiguous matches to a language model for a second opinion
  • Evidence pipeline -- Webhook feedback from Sonarr, Radarr, and the rest of the *arr family becomes ground-truth, so the classifier improves over time
  • Multi-tier auth -- API-key, reverse-proxy header, forwarded-user, and SSO -- pick the layer that fits your network
  • Operator dashboard -- FastAPI + vanilla JS with six tabs covering crawl health, classifier metrics, evidence review, retention, and more
  • TMDB poster integration -- Movie and series results include poster art pulled from TMDB
  • Retention controls -- Age-off, category filters, and manual purge so your database stays the size you want
  • Wantbridge -- Active content acquisition that prioritizes torrents matching items your *arr clients are actually searching for
  • Torznab API -- First-class compatibility with Sonarr, Radarr, Prowlarr, Lidarr, and Readarr -- add BitAgent as a custom indexer and you are done
  • Quickstart -- Docker Compose, one API key, and a working indexer in 15 minutes
  • Architecture -- How the Go core, Python dashboard, classifier, and evidence pipeline fit together
  • FAQ -- Common questions about crawling, legality, resource usage, and integration
  • Integrations -- Per-app setup guides for Sonarr, Radarr, Prowlarr, Lidarr, and Readarr Walkthrough of the operator dashboard and the improvements over upstream bitmagnet
