App Prototype

Generate a sandboxed static app prototype.

Pro workspaces can turn a narrow prompt into a contained HTML, CSS, and JavaScript preview. The output runs in a sandbox iframe; it is not a production deployment.

Sandbox boundary

The API validates generated code, strips blocked JavaScript from unsafe previews, and labels deterministic provenance.

Anonymous prototype previewSample output

This static example shows the shape of a generated micro-app before signup. It uses no customer or workspace data and does not execute code. Sign in with a Pro workspace to generate a sandbox preview from your own narrow prompt.

Sandboxed shape

Example prompt

Create a weekly launch-readiness board with an owner, status, and next decision for each work item. Keep all interactions local to the preview.

The prompt is illustrative. It is not submitted to an AI provider from this preview.
