License

AuthCore is open source under the Apache License 2.0 with the Commons Clause. The LICENSE file in the repository is the only authoritative text. This page is the plain-English version, written for server owners and developers.

In short

AuthCore costs nothing and is free for any purpose, including commercial ones. You can run it, change it, and build a business around it. The single thing the license does not allow is selling AuthCore itself, or selling something whose value is essentially AuthCore.

What you can do

• Use it anywhere: personal servers, community servers, commercial networks, modpacks and launchers.
• Self-host and redistribute: run your own copies and share unmodified or modified builds with others.
• Fork and modify: change the source for your own needs, fix bugs, add features, publish your fork.
• Build products and services around it: plugins and integrations against the AuthCore API, setup and maintenance services, server hosting, and paid tools that use AuthCore as one component among many.

What you cannot do

• Sell the software itself: AuthCore, or a hosted or managed version of it, may not be offered for sale as a paid product.
• Sell a mere wrapper: no paid product or service whose value derives entirely or substantially from AuthCore's functionality.
• Strip attribution: license and attribution notices must stay intact, and AuthCore may not be presented as your own software.
• Use our names or marks: PotenFYR Studios names, logos and trademarks may not be used to brand or promote derivative works.

Attribution requirement

The Commons Clause is part of the license, not an add-on. Any copy of AuthCore, in source or binary form, must keep the license notices that carry the Commons Clause text. Forks, redistributions and custom builds all inherit this.
