Show HN: Prvue – Self-managed preview environments for back end apps

1•dan_le_brown•1h ago
I've built an open-source tool for managing isolated preview environments (per PR) for backend applications. Currently provisions servers on DigitalOcean.

Inspired by Netlify/Vercel's preview links for frontend apps, I wanted something similar for backends. Frontend apps are generally stateless and simple to preview, but backend apps work with databases, Redis, message brokers, etc., which made building a framework that works for different application types quite tricky.

I recently discovered Railway offers something similar, but I still wanted to build the tool I wished existed. The learning process has been incredibly rewarding.

Built with Docker, Terraform, and Ansible. Supports NestJS, Laravel, Node.js, Rust, Go, PHP, and more.

Docs: https://docs.prvue.dev

Demo videos coming soon. Open to collaborations and contributions!
