Redis Stack and Our Redis Modules Are Now Standardized Under a Dual License: RSALv2 and SSPL

The Redis community has introduced a dual license for Redis Stack and its modules, including RSALv2 (Redis Source Available License) and the Server Side Public License (SSPLv1). This change aims to provide more freedom and clarity to users while addressing challenges faced with the previous RSALv1. The new RSALv2 is a permissive non-copyleft license, making its permissions and limitations clearer. SSPL, on the other hand, is becoming the de facto standard for source available licenses and is used by millions of developers worldwide. This dual-license approach allows users to choose between a more permissive but less well-known license (RSALv2) or a more standardized copyleft license like SSPL. The default binary distributions of Redis Stack and its modules will be licensed under RSALv2, while the source code can use either RSALv2 or SSPLv1.
