FAQ
Common questions
Is it really free?
Yes. Ferromagnet is free for personal and commercial use, with no activation or subscription. The app is closed source; third-party components retain their own licenses.
How does it work with Jellyfin or Plex?
Ferromagnet handles search and previews. Your torrent client downloads the files, and your existing import workflow adds them to Jellyfin or Plex.
Where do search results come from?
Results come from torrent metadata discovered by your instance over DHT. Each installation builds its own index. Enable discovery during setup and leave the crawler running to populate it.
Does it download or upload files?
Discovery fetches metadata. Choosing a preview downloads torrent content into temporary storage, which consumes disk space and bandwidth. Preview peer uploads are disabled. DHT discovery still exchanges network messages with peers.
Can I expose the web interface to the internet?
Start with loopback HTTP and an SSH tunnel. For a shared deployment, use HTTPS, native Basic Auth or a trusted authentication proxy, and edge rate limits. The ingestion admin token does not protect previews. Preview links can grant temporary streaming access to anyone who has them.
Where can I run Ferromagnet?
Use the Linux download on a Whatbox seedbox, VPS, or local server. The setup guides cover access, authentication, and discovery. Crawler concurrency, preview sessions, and cache limits are configurable to suit your server.
