🐧 Tuxery

License

Tuxery is licensed under the GNU Affero General Public License v3.0 or later (AGPL-3.0-or-later) — a strong copyleft license, and specifically the one built to close the "SaaS loophole" that plain GPL leaves open: modify GPL code and run it as a web service without ever handing anyone a binary, and GPL alone never requires you to share the source. AGPL closes that.

What that means, depending on who you are

Individuals

  • Use, read, and study the code freely.
  • Modify it for your own use — no obligation to share anything you never distribute.
  • Share a modified copy with someone — the source has to come with it.

Non-profits and communities

  • Run your own instance, fork it for your community, adapt it freely.
  • If people use your modified version over a network (a hosted instance, not just your own machine), you have to offer them its source.

Companies

  • Commercial use is allowed.
  • The network clause still applies: run a modified version as a service — even internally, even without a traditional "release" — and AGPL requires offering the source to anyone who interacts with it over the network.

Obligations

Keep noticesCopyright and license notices stay intact in anything you redistribute.
Disclose source for network useRunning a modified version as a network service counts — offer its source to users, not just people you hand a copy to directly.
State your changesMark what you modified, and when.
Same licenseModified or combined works stay under AGPL-3.0-or-later — no relicensing under something more permissive or proprietary.

The one thing worth remembering: fork Tuxery and run it as a service other people can reach — even privately, even without ever shipping a binary — and AGPL requires making that version's source available to them. That's the whole point of choosing AGPL over plain GPL for a web app.
