Cypher System Open License

The Cypher System Open License (CSOL) allows publishers, gamers, and members of the public to freely create and publish tabletop roleplaying games compatible with, and using the rules from, the Cypher System—and to market them as compatible with the Cypher System.

Through the Cypher System Open License, publishers may duplicate content from the Cypher System Reference Document (CSRD), a version of the Cypher System rules that includes nearly all rules content in the Cypher System Rulebook. Character generation, core game rules, optional and variant rules, creatures, cyphers, items, artifacts, and more are included in the Cypher System Reference Document. Text from the CSRD may be duplicated, in part or in full, within products created under the Cypher System Open License.

You can create and publish adventures, settings, supplements, and even entire, self-contained games powered by the Cypher System under the CSOL. You can modify, change, and add to the rules in the CSRD as best serves your vision. The CSOL allows you to publish products for free or for profit, in print or digital form, as long as you comply with the terms of the license.

Make the most of the Cypher System’s amazing flexibility, ease of play, narrative focus, and fun gameplay as you bring your creativity to life!

You can find the Cypher System Open License, and the Cypher System Reference Document, at the Cypher System Open License site.

Please note that the Cypher System Open License, although open in nature, is a legal agreement that you enter into with Monte Cook Games, LLC, if you publish under its terms. This page’s depictions of the CSOL’s terms are descriptive only; refer to the Cypher System Open License for actual terms and conditions. Be sure you read, understand, and agree to the terms of the Cypher System Open License before publishing.
