As footnote 1 in the featured article mentions, Redis is not open source anymore. From Redis [1]: > Redis is source-available software, available under both the Redis Source Available License v2 (RSALv2) and the Server Side Public License v1 (SSPLv1). > Redis Stack and all Redis modules created by Redis Ltd. (e.g., RediSearch, RedisJSON, RedisGraph, RedisTimeSeries, and RedisBloom) are dual-licensed under the Redis Source Available License v2 (RSALv2) and SSPL. > Redis Enterprise is closed source and requires a commercial license from Redis Ltd. There are previous versions of Redis under the 3-clause BSD license (free and open source [2]) [1]: > Can I continue to use versions of the products that were provided under the original 3-clause BSD license? > Yes. The license change is not retroactive. This means all source code and releases prior to the change remain under the 3-clause BSD license. You may continue to use those versions indefinitely under the original license, as long as you abide by its terms and conditions.
