Genie — AI coding assistant for existing projectsGenie

Genie vs v0

v0 generates polished UI from a prompt, but only for Next.js/React and only on GitHub. Genie works on your existing codebase \u2014 any stack, any provider \u2014 and ships the full change including backend, preview, and PR.

What v0 cannot do

Any stack, not just React

v0’s preview and generation are optimised for Next.js and React. Genie previews your actual project on any stack — Node.js, Python/Django, PHP/Laravel, Ruby/Rails, or static HTML — in a real cloud container.

Any source provider

v0 only connects via GitHub. Genie connects from GitHub, GitLab, Bitbucket, or a ZIP upload — so it works regardless of where your code lives.

Full-stack + deploy

v0 generates UI snippets for you to paste in manually. Genie makes the full change — frontend and backend — previews it live, and deploys to Vercel, Netlify, Railway, or your own pipeline.

Generator vs evolver

v0 is a UI generator — you paste a prompt, it gives you a fresh component to copy into your project. Genie is a UI evolver — it reads your existing components, theme tokens, and API contracts, then makes targeted changes that fit naturally into your codebase and opens a pull request ready for review.

Which one is right for you?

Choose v0 if…

  • You need a polished UI component quickly from a blank state
  • You are prototyping a new UI concept to show a client
  • You use the Vercel / shadcn/ui design system
  • You are comfortable integrating the generated code manually

Choose Genie if…

  • You want changes that match your existing design system
  • Your project is Python, PHP, Ruby, or anything non-JS
  • Your code lives on GitLab or Bitbucket
  • Your UI changes need backend / API work too
  • You want to deploy to Vercel, Netlify, or Railway automatically
  • You want a pull request, not just file snippets to copy

Common Questions

v0 can accept existing code as context but it regenerates components rather than making surgical edits. It doesn’t understand the rest of your project — your routing, state management, API calls, or database schema. Genie reads your entire repository first, so changes integrate naturally with everything already there.
Genie handles full-stack changes in a single conversation turn. Describe the feature and Genie will update the frontend component, add or modify the API endpoint, migrate the database schema if needed, and show you a live preview of the complete working feature.
Yes. Genie’s live preview supports any runnable stack: Node.js (React, Vue, Angular, Svelte, Next.js), Python/Django, PHP/Laravel, Ruby/Rails, and static HTML/CSS. The preview runs in a real cloud container on Fly.io — not a JavaScript sandbox — so your actual stack is built and served as-is.
