NestJS, Prisma, PostgreSQL, Cloudflare R2
Open SourceAuth-Pro
Auth-Pro is a production-ready authentication, email, and storage microservice built with NestJS, Prisma, and PostgreSQL. It offers a self-hosted alternative to Supabase's auth, email, and storage layers — use your own Neon database, SMTP provider, and Cloudflare R2 bucket with full ownership of every layer.
Problem Solved
Teams building modern web apps often rely on bundled auth/email/storage platforms that create vendor lock-in, unpredictable pricing at scale, and limited control over infrastructure. Auth-Pro solves this by giving developers a modular, self-hosted foundation with JWT auth, transactional email, and media storage they fully own.
