Pathway is distributed under a free and source-available license: the Pathway Business Source License (BSL), converting to the open-source Apache 2.0 license after 4 years.
This core product is free for production use, with the exclusion of providers of "Stream Data Processing Services" mentioned in the license, such as cloud hosting providers reselling products to others.
On a historical note, the BSL license originates from MariaDB, and has been adopted by companies such as CockroachDB, Redpanda, ReadySet, and numerous other organizations.
Pathway for Enterprise includes extensions of Pathway functionalities particularly useful in enterprise deployments: please take a look at our feature comparison. Use of Pathway for Enterprise is governed by separate commercial licenses. Do not hesitate to reach out to us for more information.

For the sake of clarity, a Stream Data Processing Service would include providers of infrastructure services, such as cloud services, hosting services, data center services and similarly situated third parties (including affiliates of such entities) that would offer the Licensed Work, possibly in connection with a broader service offering, to their customers or subscribers.
