Browse prompts, filter by tag, and copy with one click.
How It Works
The frontend is built with Next.js and React. When you do something like create a prompt or vote, the app calls one of our API routes which talks to Supabase (thats where the database and auth live). For the feedback form we also send an email through Resend. The whole thing is deployed on Vercel.
Check out the ERD in the docs folder if you want to see how the tables are set up.
What & Why
The idea is pretty simple - how you word a prompt to ChatGPT or Claude makes a huge difference in what you get back. So why not have a place where people can share the prompts that work well? You can post prompts, tag them, vote on them, etc.
Built with Next.js 16 + React, Supabase for the database/auth, Tailwind for styling, and deployed on Vercel. TypeScript for the whole thing.
