One-time · priced by headcount
muster is free for any organization with fewer than 25 employees, every feature included. At 25 or more it needs a license — a one-time purchase per company, priced by headcount, that never expires.

how the license works
A single payment, and every release you are licensed for runs forever, with no subscription or renewal. Twelve months of updates are included, and if your company grows into a higher band you pay the difference once.
There is no license key and no activation step. muster never gates a feature and never phones home — your Polar receipt is the proof of license.
the license
muster is licensed under the Business Source License 1.1. You may use it in production if your organization has fewer than 25 employees, provided you don't offer muster itself as a commercial hosted service. Three years after each version ships it converts to Apache-2.0, and the source is public today.
