Redis has reverted to an open source licensing model with the introduction of the GNU Affero General Public License (AGPL) for Redis 8, following criticism of its previous Server Side Public License (SSPL). While this shift aims to satisfy the open source community, some developers still find the AGPL too restrictive, and alternatives to Redis are being considered by many users.

Valkey 9, an open-source key-value database forked from Redis, is set to enhance multi-tenant clustering and improve resource optimization with its upcoming release. It aims to allow multiple applications to share a single Valkey instance, addressing community demands for better handling of microservices and data management. Additionally, it will include high availability features and a safer shutdown mode, positioning Valkey to evolve into a more versatile general-purpose database beyond just caching.
