“The modules in question are used to help create managed services on top of Redis, namely RediSearch, Redis Graph, ReJSON, Redis-ML, and Rebloom. Licensed under Apache 2.0 modified with Commons Clause, these can still be freely used in any application, though they can’t be used in a commercial Redis-based offering. For that, you will have to call Redis Labs and work out a paid licensing arrangement.”
