Hazelcast Community License

The Hazelcast Community License is identical to the Confluent Community License 1.0, which includes an Excluded Purpose designed to prevent service wrapping.

“Excluded Purpose” is defined in the license as making available any software-as-a-service, platform-as-a-service, infrastructure-as-a-service or other similar online service that competes with Hazelcast products or services that provide the software.

The software remains open, or source available, in the Hazelcast GitHub repository.
