Beta launching soon

Edit your UI without code —
in a safe environment

Tired of waiting days for a simple UI change? SafeCanvas lets non-developers modify UI directly, while keeping your payment and auth logic completely protected.

Free your dev team from UI tickets — so they can focus on what actually matters.

We'll notify you when beta is ready.

Clearly separates
what's safe to edit

The moment you connect your GitHub repo, SafeCanvas scans everything. UI components show green. Payment, auth, and database logic show red. Clear boundaries make AI adoption safe for everyone.

AI writes the code

No tickets, no Slack messages. Type what you want in plain language and SafeCanvas modifies only what's inside the guardrails. Requests that go out of bounds are automatically rejected.

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 currently preparing for beta launch. Leave your email and we'll notify you the moment it's ready.
