The echo-mem README says the shared-memory server for AI agents relicensed from Apache 2.0 to the Business Source License 1.1 on 25 September 2026, so running it in production is now free only for organisations under 50 employees and under $5 million in revenue, while larger operators and anyone offering it to third parties as a hosted service must reach an agreement. Development, testing, evaluation, research, and teaching stay free at any size, each new release converts to Apache 2.0 four years after publication, and everything published up to and including version 0.4.1 on PyPI stays Apache 2.0 permanently. The project sells a hosted database for $99 a month.
