tunle VS Magnetico

It can be both. We can get a lot of cool stuff for free, including federated services like activitypub based Twitter, Reddit, and yes even Youtube alternatives, if someone adds I2P support to this docker container https://github.com/retenet/tunle as usual I'm working on it(https://i2pgit.org/idk/tunle) but if someone else can do it faster then I'm happy to back off and help them instead. Transparently proxying a docker container to I2P-enable ActivityPub S2S connection instantly makes supporting ActivityPub and WebTorrent apps easier.

This is really neat. I'll need to check it out. A couple years ago I ran my own instance of Magnetico (https://github.com/boramalper/magnetico), but this project looks a lot more polished.

This is likely your best bet, but I'd recommend you use postgres over sqlite, this is however where development died so some features like search or stats aren't implemented while using pg as the db.

You can create decentralized bittorrent indexers though (see https://github.com/boramalper/magnetico as an example)! This means you can search for bittorrent files without having to rely on a centralized service (although building the index does require some time & storage space of course).

Someone else did this a while back, universe continues to exist.

I just get a rickroll gif on your link. Did you mean this project?

"Autonomous (self-hosted) BitTorrent DHT search engine suite."

Although I admit, that I would love to see a maintained DHT search solution (like magnetico or dhtcrawler2).

Yeah, you probably found it. Abandoned, yes, but not necessarily unfinished.

A magnet search is easy enough to self-host, I can provide you with instructions to self-host a clearnet magnet search engine over I2P in the meantime, but you can probably figure it out from this: https://github.com/boramalper/magnetico which is an easy to self-host DHT search engine.
