I built an AI tool to go from 'Idea to React Native App' in minutes
Hey everyone. 👋
I’ve spent the last 6 months building GenVibe with one goal: To give developers a tool that balances speed with code ownership.
While there are great tools out there, I found myself constantly stressing about credit limits or getting locked into proprietary hosting. I wanted a platform where I could just build.
What GenVibe does differently:
True Full-Stack Generation: whether you need a responsive Landing Page (React) or a native Mobile App (React Native/Expo), GenVibe generates clean, runnable code.
Code Ownership: You aren't rented a 'viewer.' You get the full source code to deploy anywhere (Vercel, Netlify, or your own server).
High-Quality Free Tier: I offer 5 daily generations using top-tier models (like Opus) so you can build serious projects for free, not just toy prototypes.
Who is this for?
Founders and devs who want to go from 'Prompt to Production Code' without hitting a paywall every 10 minutes.
Try it out:
I’d love to see what you build. If you find a bug or have a feature request, drop it here—I’m shipping updates daily.

Impressive that you built this solo. How are you managing LLM costs while offering a free tier?
Thanks! It was definitely the hardest part to balance.
The secret is a hybrid model architecture.
I don't burn expensive tokens for everything. I use lightweight, optimized models (like Haiku/Flash) for handling conversation history, context selection, and intent understanding.
I only call the heavy hitters (like Claude 4.5 Sonnet / Opus) for the actual Code Generation step where quality matters most.
This routing strategy cuts my costs by ~70%, which allows me to pass those savings to users as a generous free tier instead of charging for every token.
