Redis has announced that it will transition to a dual licensing approach for its core software starting with Redis 7.4, using the Redis Source Available License version 2 (RSALv2) or the Server Side Public License version 1 (SSPLv1). The new licenses aim to balance making Redis source code broadly available while protecting the company's ability to invest in feature-rich products and enterprise offerings. The dual license approach will unify core Redis with Redis Stack, including advanced data types and processing engines, as downloadable software. Organizations providing competitive offerings to Redis will no longer be permitted to use new versions of the source code free of charge under either of the dual licenses, but commercial licensing terms are available for such cases. The change does not affect end users of Redis' open-source products, third-party libraries that leverage Redis, or existing commercial customers of Redis.
