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.

Yea same, PieFed has so many features that Lemmy simply doesn’t. I prefer it so much that I just use it in the browser on mobile, till a good mobile app is available.
