Hey Product Hunt!
I’m Ivan, founder of Vratix, where we’re on a mission to make backend development as delightful as frontend “vibe coding.”
We started with an open source library of reusable API modules and now I am introducing the public beta of Line0 - the first AI pair programmer built specifically for backend developers.
Until now, most AI coding tools have focused on generic autocomplete or no-code web apps - backend has largely been left behind. With Line0, you can build a fully functional API service in just a few prompts:
🎯 Generate APIs with AI
🔄 2-way GitHub sync
✨ Prompt enhancement
👥 Team collaboration
And we’re just getting started. In the coming weeks you’ll also get:
🖥️ In-browser sandbox previews for your newly generated endpoints
📄 Auto-generated documentation
🔗 Swagger-to-API conversion
🌐 Dependency graph visualization
🤝 Live collaboration
Your feedback will shape our roadmap - we want to build the most advanced AI-native backend platform, from infrastructure design and code generation to cloud provisioning and maintenance.
Excited to see what you guys build and what you think of Line0!
Thanks for hunting - and happy coding!

This looks incredibly promising! As someone who spends a lot of time building backend services, having a tool that understands the complexities of API generation, integrates with GitHub, and supports prompt-based coding is a total game changer. Excited to see how the team evolves the in-browser previews and auto-generated docs — those will be huge productivity boosters. Congrats on the launch, Ivan and team!

@suryansh_tiwari2 Thanks a lot Suryansh!! I totally agree with you - the complexities of backend development can sometimes be a huge pain and with Line0 we hope that we eliminate all the busy work and make it much simpler for everyone to build :)
Thanks for the support 🫡
