Bitmagnet is a self-hosted BitTorrent DHT crawler and metadata indexer that continuously discovers torrents from the network, extracts metadata, and stores it in a local database. It exposes a web UI and API so you can search, inspect, and integrate torrent metadata into your own applications or download automation.

Key Features

BitTorrent DHT crawling to discover infohashes without relying on public tracker listings
Metadata fetching/parsing (magnet/torrent details such as name, files, sizes) and persistent storage
Searchable index for discovered torrents (query/browse discovered metadata)
HTTP API for programmatic search and metadata access
Runs as containerized services for repeatable deployment
Designed to run continuously to build and maintain a local catalog over time

Use Cases

Build a private torrent metadata catalog for research, archiving, or internal tools
Feed torrent discovery results into download automation pipelines (via API)
Run analytics on observed torrent metadata (trends, file lists, sizes) from your own dataset

Limitations and Considerations

Crawling the DHT and accumulating metadata can require substantial CPU, bandwidth, and disk depending on retention and scale
Coverage depends on DHT visibility and successful metadata retrieval; not all discovered infohashes will yield metadata

Bitmagnet is best suited for users who want a locally controlled torrent metadata search/index backed by continuous DHT crawling. Its API-centric design makes it useful as a building block for custom discovery, automation, and analysis workflows.
