Which Compose version is produced?

The modern schema without a version key, which Docker Compose v2 expects.

How do I write ports?

One mapping per line in host:container form, for example 8080:80.

Can I validate the result?

Yes — paste it into the Docker Compose Validator tool to check the structure.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.

About the Docker Compose Generator

Add services one by one — image, ports, environment variables, volumes and dependencies — and get a clean docker-compose.yml you can copy or download. Useful for spinning up a local stack of app, database and cache containers without memorising the YAML shape.
