This is what I’ve been using for a few days: https://github.com/soundjester/lemmy_monkey

For Matrix, I’d recommend conduit over synapse, with the expectation that all of synapse’s features haven’t yet been added (most notably support for spaces, which may or may not be a dealbreaker).

It’s incredibly easy to set-up and very lightweight. I never self-hosted synapse due to how resource-heavy it is, and constantly had issues with dendrite racking up resources as well.conduit has honestly been the easiest thing I’ve self-hosted.

here’s a list of public searx & SearXNG instances

If anyone has good experiences with any of them, definitely share!
