Licence

Free software. Including at work.

Salt.md is published under the GNU Affero General Public License v3.0. No fee, no separate licence, no conversation with us required. There is exactly one condition, and most people never touch it.

What you may do, and the one condition

What you may do

All of it, without asking anyone. Running Salt.md unmodified for your own people asks nothing of you at all.

  • Run it for yourself, your team or your whole company
  • Use it commercially, internally, at any scale
  • Modify it and run your modified version
  • Self-host it on any hardware you like
  • Hand a copy to a colleague or a client
  • Read every line and audit what it does

The one condition

It applies only when both halves are true: you changed the code, and you let other people use that changed version over a network.

  • Changed it, and others use it over a network → publish your changes
  • Changed it, but only your own people use it → nothing to publish
  • Did not change it → nothing to publish, ever

This is the whole of what the AGPL adds over the GPL. If you are unsure which row you are in, ask before you build: salt-md/salt.md/issues

The fine print, in plain words

The name is ours

Redistribute it as Salt.md and you are welcome to. If you fork it into something of your own, please give that something its own name. The licence covers the code, not the identity.

Why this licence

Two goals in tension. Salt.md should be in as many hands as possible, which rules out anything a legal review rejects on sight — and the previous licence forbade all commercial use, including a company simply running it internally. That was exactly the wrong door to close.

What it still prevents

Handing a competitor a finished product to close up and sell. The AGPL does not forbid that either. It means their version has to be as open as this one, which removes the incentive without shutting anybody out.

What lives elsewhere

Anything built on top — hosted convenience, assistant features — lives in its own repository under its own terms. The core stays free software.

No warranty

Salt.md comes with no warranty, to the extent permitted by law.
