Hey Product Hunt!
I built this because I was rewriting the same comment system for every Next.js project. Not hard — just tedious
boilerplate that eats hours.
So I extracted it: copy 3 component files, run 1 Supabase migration, your comments and likes just work.
What makes it different:
- Not a SaaS — you own the code, host it yourself
- Not a heavy library — ~800 lines of TS you can read and modify
- Not a UI kit — uses Tailwind, matches your design
The repo is 100% MIT open source. There's also a Complete Package on Gumroad ($29) with video walkthrough and bonus
templates — but everything in the repo is fully functional on its own.
Built this solo. Would love feedback on the API design and Supabase RLS patterns. Happy to answer questions!
