About Quad Build

Software should be limited by your ideas, not your ability to write code. Quad Build turns a plain-language description into a working, production-grade web app — with the code, the repo, and the infrastructure under your control, not ours.

Describe what you want. Quad Build’s AI agent writes the app file by file, boots it in a live sandbox while it’s still generating, and iterates with you until it’s right. When you’re ready, one click pushes a real repo to GitHub and deploys to Vercel — optionally wired to a Supabase project you already own. You keep everything: the code, the data, and the billing relationship with your own providers.

Quad Build is made by Quad, the team behind quad.chat. We build tools that put capable AI where the work happens — and that respect the person using them.

• You own the output. Exported code is yours. We don’t hold your project hostage.
• Speed is a feature. The preview runs while the app is still being written.
• Fewer choices, better defaults. Three model lanes. One picker. That’s it.
• Trust by default. Clear legal pages, honest security practices, and infrastructure you can audit.
