Ask ChatGPT or Claude for a website and get a link anyone can open. Add Toupas on the web once, and it works in every chat, on your computer and your phone.
How it works with a coding agent
Ask your agent
“Make this app live.” It installs Toupas and works out how your app runs.
Approve sign-in
The first time, you click one link to sign in. That’s the only thing you do.
Open your link
Your app is at yourapp.toupas.app. Ask again after changes: the link stays the same.
Toupas works out what your app needs.
Websites
React, Vite, Astro, plain HTML and other sites made of files.
Apps with a server
Node.js, Next.js, Express, Python, FastAPI and Flask.
A database
Postgres for apps that save data. Your local data can come along, if you say so.
File storage
For uploads and images, kept safe when the app updates.
Your own name
A custom name on toupas.app, or your own domain.
Help when it breaks
Your agent reads the app’s logs and status and fixes what’s wrong.
Questions about hosting with Toupas
Can Toupas host my website?
Yes. React, Vite, Astro and plain HTML sites get a link like yourapp.toupas.app, or you can use your own domain.
Can it host an app with a server and a database?
Yes. Node.js, Next.js, Express, Python, FastAPI and Flask apps, with Postgres and file storage. Ask a coding agent, or use the terminal.
Can I publish a website I made in ChatGPT or Claude?
Yes, from the chat, even on your phone. Add Toupas once.
Can ChatGPT or Claude build an app with a login and saved data?
Yes. Describe the app in the chat, and it goes live with sign-in, saved data and control over who sees what. Payments and other custom logic need code, and the app can move to code later.
Can I make my app live from VS Code?
Yes. Get the extension and click Make live in the status bar.
