What a business may do with it
Network copyleftAGPL-3.0
Like the GPL, and offering a modified version to users over a network counts: they are owed its source.
This describes the licence family GitHub identified, not legal advice about this project. The repository’s own LICENSE file is what binds you.
Run it yourself
Mastodon’s README does not show a docker run, docker compose up or helm install in a code block, so this page will not guess one. It may be a desktop app, a library, or documented on its website.
