VibeSafe Builder is an AI app builder. You describe the app you want in plain English, and it writes a working web app you can preview, change by chatting, publish to a shareable link, or download and host anywhere. It lives at vibesafebuilder.com and is made by SG Digital Ventures LLC.
What makes it different from other AI app builders is what happens around each build: you see what a build will cost before it runs, every change can be rolled back, and every version is security-scanned before you can publish it.
01VibeSafe Builder is not the same as vibesafe.info
The names are close, so this causes confusion. They are two separate products from the same company:
- VibeSafe Builder (vibesafebuilder.com) creates apps from a description.
- vibesafe.info is an AI code security scanner. It checks code you already have, including apps built with Lovable, Bolt, Cursor or Replit.
Neither is affiliated with vibesafe.net, vibesafe.dev, vibesafeai.com or vibe-safe.net, which are unrelated products that happen to use a similar name.
02What it does
- Builds from a description. Start with a sentence, or from one of 15 free templates, and keep asking for changes.
- Shows the cost first. An estimate appears before every generation, and you can set a hard spending cap.
- Doesn't charge you for failures. Failed generations are tracked separately from your build spend.
- Breaks fix loops. If the same fix fails twice, the next attempt re-diagnoses the problem instead of repeating itself. The reasoning is in the AI doom loop.
- Keeps every version. Full history with diffs and one-click rollback.
- Scans before you publish. Every build is checked for hardcoded keys,
eval()and unexpected outbound requests, and publishing is blocked on a critical finding. Launch Check also opens the app in a real browser. - Grows with the project. Simple apps are a single file you own. Bigger ones can be multi-file React projects, pushed to your own GitHub repository and deployed to your own Vercel account.
03Who it's for
Founders, indie hackers and anyone who wants a working app without writing it, and who cares about cost, code ownership and security, not just speed. It suits prototypes and MVPs, internal tools, calculators, trackers and generators, and apps with shared or per-visitor data.
It is not yet the right tool for payments or business logic that must run where users can never see the code, or for custom server-side endpoints beyond the built-in data backend.
04What it costs
- Free trial: every new account gets 1 free build. It uses a lighter AI model (Claude Sonnet 5), so the result is less polished than paid builds.
- Bring your own key: no platform fee. You connect your own Anthropic API key and pay Anthropic directly, with no markup.
- Managed: $15 a month with $10 of AI usage included and no API key needed. It pauses at the limit instead of charging more.
Both plans use Claude Opus 5. Full details are on the pricing page.
05Try it
The quickest way to see how it works is the interactive demo, which needs no account. When you're ready, open the builder and your first build is free.
