Java spring for backend, Go for federation, Next.js for frontend
demo.sublinks.org has the backend with the lemmy-ui frontend to show api compatibility
Task list and progress is public on the github org https://github.com/orgs/sublinks/projects/1
Matrix space where all the devs talk is also public and you can see progress talked about in them
Theres been a bunch of activity and people joining in in the dev matrix already
Backend pretty much already has parity and the frontend is currently the main thing that an updated demo is waiting on but should be ready really soon
I’ve been designing an updated home page recently for it that I’ll be pushing out this week that looks miles better than lemmy-ui since I could do everything from scratch and thus quickly
