Use cases
Mythex is for apps and websites you can preview in the browser and publish to a public link. Each guide below is a thin, shippable slice: a starter prompt, the usual build loop, and honest limits (for example app login and payments are bring-your-own). If you already know the niche, you can also start from a template prompt at mythex.ai/templates.Stack and language
You do not have to use a specific language. The starter prompts below assume a normal web app (default is Vite + React + TypeScript + Tailwind). If you care about the stack, say it in the first message:- Front end: Next.js, static HTML, or keep the default Vite + React
- API / backend: Node, Python, C#, Java, and similar — ask for a Dockerfile; publish deploys the container to Fly
- Both at once: a website plus an API in one project — multi-service preview

The same loop every time
- Describe the product in plain language (workflow, not a feature dump)
- Preview on desktop and the phone-size frame
- Iterate in Build — use Plan before big changes
- Add a database or uploads when data must persist
- Run App Testing (
/test) on the happy path - Publish a public URL
