VibeSafe Builder is an AI app builder — describe an app in plain English and it writes a working one. The difference: other AI app builders bill you for their mistakes. This one shows every cost before you spend it, makes every change reversible, and scans every build before you publish.
For founders, indie hackers, and anyone building an app who wants control over cost, code, and security — not just speed. Prototypes, internal tools, MVPs, landing pages, small SaaS apps.
Every app starts as one portable file with zero setup. When a request needs more — accounts, shared data, a real codebase — the builder grows into that instead of hitting a wall.
Outgrow it? A single-file app is a plain file you can hand to a developer — no export step, no proprietary format. A React project is real, ordinary code in a repository you own. No lock-in either way.
A guided walkthrough of the real workspace — same tabs, same copy, same flow you'll see in the builder.
This is a guided illustration of the real interface, not a screen recording — open the builder to try it for real.
We researched thousands of reviews of the big vibe-coding tools. Each thing users hate became a feature users get.
Failed generations are tracked separately from your build spend — the meter shows exactly what went into your app versus what the AI wasted.
A live estimate appears before every generation, with a hard spend cap.
Roll back to any version with one click.
Two failed fixes in a row and it re-diagnoses from scratch.
One click puts your app live at a shareable link — security-checked before it goes out.
Hardcoded keys, eval(), insecure requests, data exfiltration — checked on every generation using the same scanning engine as VibeSafe, pass/fail before you share.
Full code always visible. Download your app as a single portable HTML file and run it anywhere.
Instant v1, zero generation cost. Pick one, then keep chatting to make it yours.
