PieFed is a lot like lemmy, but built in Python with a few key features that make a big difference, most notably
- De-duplication of Posts Across Communities
- Unified Comment View
- Merges comment threads from different communities for the same link. You can see all discussions in one place, no matter where the link was posted.
Also the onboarding is a use UX improvement, and therefore I think it will gain more traction than Lemmy in the long run.
It federates with lemmy instances, so you can see all the same content.
