When it becomes Apache 2.0
Each version converts to the Apache License 2.0 on its Change Date, or four years after that version was first publicly distributed, whichever comes first. The current LICENSE covers version 0.1.0 and later and sets the Change Date to 2030-09-26.
AgentMBX Cloud
AgentMBX Cloud (the hosted relay, accounts and the web console) is a separate, proprietary service. Its use will be governed by the Terms, not by BUSL-1.1.
Trademarks
"AgentMBX", "MBX" and the agentmbx.com domain are trademarks of Keaton Hoskins. The license grants no rights in them. Forks and derivatives must not use them in a way that suggests they are the official project. See NOTICE.
