Welcome to Mythex
Mythex is a full-stack AI app builder in the browser. You describe what you want in plain language; Mythex builds and runs it in an isolated cloud sandbox, shows a live preview, and can publish a public URL when you are ready. You get editable code, a real terminal, an optional Postgres database, and ownership of the projects you create — not just a chat transcript of snippets.Quick start
Build and preview your first app in about ten minutes.

The core loop
- Describe the app or website you want.
- Mythex builds it in a cloud sandbox (files, packages, processes).
- Preview the running app in the browser.
- Chat to iterate — change copy, layout, data, or behavior.
- Publish to a public link when you are ready.
What makes Mythex different from ChatGPT
Who Mythex is for
- Founders validating MVPs and demos
- Small businesses that need a site or simple tool
- Freelancers & agencies shipping prototypes faster
- Students & makers learning by building
- Developers who want a sandbox, preview, and publish path without local setup
What you own
You own the applications and content you create. Mythex hosts and runs them so you can build and publish; the output is yours to keep building on or export.Next steps
