How to publish an app built with an AI tool

If your AI tool supports MCP connectors, publish straight from the chat. Otherwise, download the files and upload them. It takes about a minute.

Publish from your AI chat

Tools like Claude and Cursor can connect to Tiiny Host and publish for you. See How to connect Tiiny Host to Claude with MCP; the last section covers other tools.

Or upload your files

1. Export or download your project from your AI tool.
2. Find the folder with index.html in it.
3. Zip that folder.
4. Drag the zip onto tiiny.host.
5. Choose a link name and click Publish.

Got a single page? Save it as index.html and upload that.

Works on my computer, not once published

• It needs a backend. We can run some PHP, Python and Node.js apps on paid plans, but not databases. See Hosting apps that run server code (PHP, Python, Node.js) and Can I use a database with Tiiny Host?
• You uploaded source code, not the build. If the zip includes package.json, we try to run it as an app. Zip only the folder with index.html.

Styling or images missing? See CSS, images or files missing after upload.

Showing as a preview?

That's a plan limit: the free plan allows 3 MB per project. See Why is my project showing as a preview?
