More about Line0

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. Our roadmap include:

🖥️ 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!
