Beta launches May

Claude Design is for the products
you're dreaming of.
SafeCanvas is for the products
you're shipping.

The guardrail layer Claude Design doesn't provide. SafeCanvas lets your designers and marketers change live React UI — without touching payments, auth, or any logic that matters.

for the apps you already shipped — not the ones you're sketching.

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

Beta launches May — No spam, ever. Early tester access only.

Describe it in plain language,
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 launching May 2026. Leave your email and you'll get early access on day one.
