Interesting project, what are some similar self-hosted solutions that allow you to search torrents on public trackers?
To the author: How do you personally use it, do you have a custom interface to search the aggregated results or do you just plug it into a bigger content consumption system?
Magnetico[1] is an easy-to-use, self-hosted DHT crawler. It has a web UI that shows statistics and gives you a search engine (it uses sqlite full-text search).
It needs quite a bit of bandwidth and some storage space, but worked well so far, for me. I've been running it for a couple of years and it indexed around 12.5M torrents (36GB of uncompressed database).
