AI Full-Stack App Builder
Full-stack means the parts most builders leave out: a database that keeps your data, an API behind the screens, accounts, and somewhere it actually runs. Describe the app and Mythex builds all of it, then hands you the code.
Who it's for
Founders who need more than screens, and developers who want the scaffolding done — schema, routes, auth and deploy — before they open an editor.
What you can build
- A React frontend with API routes behind it, not mock data
- Postgres attached to the project, with the schema written for you
- Sign-up and login, scoped so each user sees their own rows
- File uploads on real storage
- A Python or Node backend as a second service when you ask for one
A prompt to start from
Build a full-stack web app with a React frontend and an API backend. Add user sign-up and login, a Postgres database where each user owns their own records, create/edit/delete for those records, file upload to storage, and an admin view. Show me the schema and the API routes, and publish it to a public URL.
Questions
What does Mythex handle on the backend?
API routes, a Postgres database you can attach in one step, file storage, environment secrets, and the deploy. The default is Vite + React with an API alongside it; ask in chat for a Python or Node service instead and it publishes through a Dockerfile.
Can a developer take it over later?
Yes. It is a normal project: standard files, a real terminal, and on Pro you export a ZIP or sync it to GitHub and continue in any editor. Nothing is locked in a proprietary canvas.
Do I need to know how to code?
No. You describe what you want in plain language and Mythex writes the code, shows a live preview, and lets you change things by chatting. The code editor and terminal are there if you ever want them.
Do I have to explain my business every time?
No. Mythex remembers who you are and how you work across every project, and follows the standing notes you set for a project, so you are not re-briefing it in each new chat. You can read, edit or switch all of it off.
How much does it cost?
There is a Free plan with daily credits, enough to build and publish a first version. Pro is $25/month and adds full code editing, GitHub export, custom domains, and credit top-ups.
