PrepPeer

AI mock interviews with real peer ranking, powered by Next.js 15, Supabase, and Groq.

Run locally

npm install
cp .env.example .env.local
npm run dev

Open http://localhost:3000.

Fill the values in .env.local before testing authenticated flows or AI interview generation. The key variables are documented in .env.example.

Generate a dedicated interview-encryption secret with:

node -e "console.log(require('crypto').randomBytes(48).toString('base64url'))"

Set that output as INTERVIEW_PROOF_SECRET locally and in the production environment. It must be at least 32 characters. When it is absent, PrepPeer derives a domain-separated migration key from existing server-only key material so deployments remain available, but a dedicated secret is preferred. Changing the root secret invalidates interviews that are currently open.

Deploy

Optimized for Vercel: import this repo, add the environment variables from .env.example, and deploy.
