Question: Is Redis Enterprise Open Source?

Answer

No, Redis Enterprise is not open source. It's a commercial product offered by Redis Labs that extends the open source capabilities of Redis. While Redis itself is an open source project, Redis Enterprise offers additional features such as:

• Active-Active geo distribution
• Active-Passive (Replica Of) geo distribution
• Diskless replication
• Redis on Flash
• Bigger datasets than RAM and much more.

These features are designed for enterprise-grade use-cases and they are not available in the open-source version. Here is a simple comparison:

| Active-Active Geo-Dist   | No                  | Yes              |
