I’m excited to announce the first alpha preview of this project that I’ve been working on for the past 4 months. I’m initially posting about this in a few small communities, and hoping to get some input from early adopters and beta testers.
What is a DHT crawler?
The DHT crawler is Bitmagnet’s killer feature that (currently) makes it unique. Well, almost unique, read on…
So what is it? You might be aware that you can enable DHT in your BitTorrent client, and that this allows you find peers who are announcing a torrent’s hash to a Distributed Hash Table (DHT), rather than to a centralized tracker. DHT’s lesser known feature is that it allows you to crawl the info hashes it knows about. This is how Bitmagnet’s DHT crawler works works - it crawls the DHT network, requesting metadata about each info hash it discovers. It then further enriches this metadata by attempting to classify it and associate it with known pieces of content, such as movies and TV shows. It then allows you to search everything it has indexed.
This means that Bitmagnet is not reliant on any external trackers or torrent indexers. It’s a self-contained, self-hosted torrent indexer, connected via the DHT to a global network of peers and constantly discovering new content.
The DHT crawler is not quite unique to Bitmagnet; another open-source project, magnetico was first (as far as I know) to implement a usable DHT crawler, and was a crucial reference point for implementing this feature. However that project is no longer maintained, and does not provide the other features such as content classification, and integration with other software in the ecosystem, that greatly improve usability.
Currently implemented features of Bitmagnet:
A DHT crawler
A generic BitTorrent indexer: Bitmagnet can index torrents from any source, not only the DHT network - currently this is only possible via the /import endpoint; more user-friendly methods are in the pipeline
A content classifier that can currently identify movie and television content, along with key related attributes such as language, resolution, source (BluRay, webrip etc.) and enriches this with data from The Movie Database
An import facility for ingesting torrents from any source, for example the RARBG backup
A torrent search engine
A GraphQL API: currently this provides a single search query; there is also an embedded GraphQL playground at /graphql
A web user interface implemented in Angular: currently this is a simple single-page application providing a user interface for search queries via the GraphQL API
A Torznab-compatible endpoint for integration with the Serverr stack
Interested?
If this project interests you then I’d really appreciate your input:
How did you get along with following the documentation and installation instructions? Were there any pain points?
There’s a roadmap of high-priority features on the website - what do you see as the highest priority for near-term development?
If you’re a developer, are you interested in contributing to the project?
Thanks for your attention. If you’re interested in this project and would like to help it gain momentum then please give it a star on GitHub, and expect further updates soon!
Scraping torrent sites will be avoided is it’ll be prohibitively slow and break the self-sufficiency concept - we’ll infer as much as possible from the torrent meta info alone. You could have a guess at the bitrate from the file sizes. Sonarr/Radarr will already do this for you with quality profiles I think.
Hi, am i missing something, the bitmagnet image keep restarting when i check with “docker ps”, the other 2 containers are working as intended.
And port 3333 doesn’t show anything.
Very nice. This gets rid of any questionably legal gray area of using sites like Nyaa, etc for Torrent links. Also provides a bit of robustness against censorship when those sites get taken down. Looks like I’m gonna have to set up proxmox on a machine this weekend, as Windows sucks dick for docker containers and that’s what I’ve got most of my *arr stuff hosted on currently.
It’ll be a good thing anyways, as most of those instances aren’t running through my VPN yet and I should just centralize them on proxmox and run all the torrents, etc through containerized instances for security.
Being relatively new to the self hosted experience and still working through how everything in an arr setup interacts, along with what issues can occur and how to troubleshoot/fix them, this sounds incredibly useful. I’ll definitely be looking into integrating this into my own setup and providing feedback when I can!
This looks kinda neat, I even tore down my whole servarr stack to give it a go, alas I can’t get bitmagnet to “talk” with prowlarr. I’m probably doing something really stupid, but I can’t figure out how to add the whole thing under a single docker network, I get errors like
network somename was found but has incorrect label com.docker.compose.network set to ""
Sounds interesting 😀 I’ll keep an eye on it, though I won’t be a primary user, I switched to usenet about a decade ago and only use torrents as a last resort.

Great project !
Naming conventions are missing some important information like bitrate, color depth, and most importantly language and subtitles.
Do you plan to scrape additional infos from known torrent sites (searching for torrent hashes for well named torrents) ?

That was easy to set up. I’ll let it churn for a few days and we’ll see how helpful it is. Thanks for the app.
Is it safe to run this without a VPN if I am just using it to index?
It’s only once you install something like this that you realize just how many torrents are porno.
I’ve always been curious about ‘Anal Police Stories 2’ but I’ve never found the time.

There’s a PR currently open for multi-platform builds so should have this sorted soon
