FAQ

Got questions

Currently React + Tailwind CSS. Connect your GitHub repo and we'll automatically scan for compatibility.
Never. SafeCanvas only accesses the UI layer. Payment, auth, and database logic are fully protected by guardrails.
Anyone can make requests, but final deployment requires a developer's PR approval. Faster iterations, without giving up control.
Yes, previews currently run on Vercel. Netlify support is coming soon.
SafeCanvas only reads code from designated folders via the GitHub API. We never copy or store your full repository on external servers. All access is granted explicitly through GitHub App permissions — and can be revoked at any time.
We're launching late April 2026. Leave your email and you'll get early access on day one.
