}Sound familiar?
Paying for broken code
Credit-based tools charge you whether the generation works or not. A failed prompt still costs you.
No idea what changed
Most tools apply AI changes silently. You only find out something broke after the fact.
AI forgets your project
Hit the context limit and the AI loses track of everything it built. You start explaining from scratch.
We built this because we felt this too.
From idea to live app in minutes.
Choose your stack
Pick your AI provider, database, auth, and deployment. Your keys. Your infrastructure.
Describe what you want
Type a prompt. Watch code stream into a real Monaco editor. Review the diff before it applies.
Deploy live
One click to Vercel, Railway, Render, or Netlify. Or share a preview link instantly.
Everything you need. Nothing you don't.
Bring Your Own API Key
Connect Anthropic, OpenAI, Google, xAI, or Mistral. Pay API rates directly — never our markup.
Diff View Before Apply
See exactly what the AI wants to change before it touches your code. Approve or discard.
Full Code Ownership
Export your entire project as a zip anytime. No hostage code. No lock-in. It's yours.
Smart + Flash Models
Routine edits auto-route to fast cheap models. Complex features use the best model available.
Share Preview Links
Get a public URL for your sandbox in one click. Share before you deploy. 2-hour live link.
Your Stack, Your Rules
Choose your own database, auth, and deploy provider. We generate code that fits your exact setup.
