The AI app builder that plans before it builds. Every app is verified, every deploy is gated, and every change is reversible.
No credit card required · Free plan includes 5 projects
How it works
Tell Zelio what you want. The plan editor guides you through every decision before a single line of code is written.
Zelio generates, verifies, and previews your app in the Build Theatre. Every step is visible and transparent.
One-click deploy to production with custom domains. Roll back to any revision in seconds.
Features
Production-ready from day one. No shortcuts.
Every project starts with a structured plan. Building only begins when the plan scores high enough.
Typecheck, lint, a11y, and perf checks run on every build. Broken apps never reach preview.
Last 50 revisions stored. Roll back in under 10 seconds. Every change is safe.
Watch your app come to life in real time. The preview pane is never blank — always informative.
Versioned UI component library. Missing pieces are auto-created and registered on the fly.
Deploy with verification gates. Custom domains, SSL, and CDN included.
Every build scanned for secrets, vulnerabilities, and suspicious outbound connections.
RBAC with Owner, Admin, Editor, Viewer roles. Workspace-level isolation by default.
Export as ZIP or push to GitHub. Clean React + TypeScript. No lock-in, ever.
