Mainbrella Build

Your idea.
A working frontend.

Describe the site or app you have in mind. Build creates the source, installs its packages, checks the production build, and opens a preview you can keep refining.

Powered by Cloudflare Workers AI and Workflows.

Mainbrella Build coordinates Workers AI inference and Linux build tools, then retains project files and Git bundles in R2 with version history in D1.
AI inference, a real Linux build, and retained project source.

From a description to a checked preview.

A familiar frontend loop, with the code and its history kept close.

  1. Describe what you want.

    Start with a page or app idea. Ask for changes in the same conversation as the project takes shape.

  2. Build and inspect it.

    Build writes frontend files, installs dependencies, runs TypeScript and Vite checks, then serves the compiled output for preview.

  3. Keep the source.

    Review versions, restore earlier work, or download the source and its Git history to continue elsewhere.
