v0 made AI UI generation mainstream. But when you need a real backend, a database, background jobs, or a language that isn't React/Next, you outgrow a UI generator fast. Fixa is an agentic software builder: it writes, runs, and debugs full-stack apps in a real cloud sandbox, in any language, with the strongest coding agent on the web.
Where v0 shines
v0 is excellent for quickly generating polished React/Next.js UI and design-system components, tightly integrated with Vercel.
Where Fixa goes further
Full product, not just the UI
Fixa builds and runs the backend, database, and APIs — not only the front-end layer.
Any language
Python, Go, Rust, Ruby, C++, TypeScript and more — Fixa isn't locked to the React/Next world.
A real machine
Your code runs on an actual cloud VM with a terminal, so the agent can install packages, run tests, and fix its own errors.
Model choice
Use Claude, GPT-5.5, or Gemini — pick the best brain for the task.
