Most buyers should pick Redis.
Redis is the clearer low-cost starting point: it has a free tier, and Essentials lists a $5 monthly total. Choose Hazelcast Platform for self-managed distributed caching, in-memory compute, stream processing, Kubernetes support, and geo/WAN replication; its annual price is quote-only. Redis Free is limited to 30 MB and one database, while Pro has a $200 monthly minimum. Neither source publishes per-seat pricing, and Hazelcast’s exact rates are unavailable.

02Pricing compared
Redis is the clearer low-cost starting point: its Free plan includes 30 MB and one database, while Essentials lists a $5 monthly total for 250 MB–100 GB. Essentials uses shared cloud deployment and includes basic support. Pro starts at a $200 monthly minimum, with the first $200 free; it adds dedicated, multi-region cloud and active-active replication. Hazelcast’s self-managed Platform is licensed annually, but its price is available only on request. Hazelcast Cloud is pay-as-you-go or prepaid, with exact rates not published. The pricing information lists no Hazelcast free plan. Redis also shows an annual-billing option without a published price. Neither source publishes per-seat pricing, so compare by deployment, capacity, and support needs—not seats.
03Features and depth
Hazelcast is oriented toward distributed caching and processing inside the cluster. Its listed capabilities include sub-millisecond data access, parallel in-memory compute, real-time stream processing, geo/WAN replication, and a choice between CP consistency and AP availability. The homepage also lists Kubernetes support. That makes it the more directly specified fit here for teams building around distributed compute and stream processing, not just a cache.
Redis combines caching and streaming with search and AI-oriented capabilities. Its platform highlights vector search and memory and context for AI agents. The listed features also include active-active multi-region replication and tiered storage that combines RAM and flash. Redis offers cloud, on-premises, hybrid, and open-source deployment options. The products overlap on caching, streaming, and replication, but the published materials emphasize Hazelcast’s cluster compute and consistency choices, while Redis emphasizes search, AI data needs, and deployment breadth. Feature fit depends on which of those capabilities your application actually needs.
04Ease of use and learning curve
Neither product’s published materials establish that it is easier to learn, and we would not treat deployment choice as proof of a simpler setup. Hazelcast offers self-managed software and a managed cloud service; self-managed licensing is annual and quote-only, while cloud rates are unpublished. Redis spans open-source and cloud deployments, with Free and Essentials offering shared cloud and Pro listing dedicated multi-region cloud. Redis’s low-cost entry point makes it easier to evaluate pricing, but the Free plan’s 30 MB and single-database limits are concrete constraints. For an operational comparison, check the deployment model and support level you need; the available information does not give enough detail to rank setup effort or learning curve.
Questions people ask
Which is cheaper, Hazelcast Platform or Redis?
Redis has the clearer low-cost entry: Free lists 30 MB, and Essentials lists a $5 monthly total. Hazelcast self-managed Platform is annual and quote-only; Hazelcast Cloud rates are not published. Redis Pro has a $200 monthly minimum, so costs depend on the tier and deployment you need.
Does Hazelcast have a free plan?
The published Hazelcast pricing information lists no free plan. It describes self-managed Platform as an annual subscription with pricing available upon request, and Hazelcast Cloud as pay-as-you-go or prepaid credits with exact rates unpublished. Redis, by contrast, lists a Free plan with 30 MB and one database.
When should a team choose Hazelcast over Redis?
Hazelcast is the stronger match in the published feature list if you need distributed caching alongside in-memory cluster compute, stream processing, Kubernetes support, or CP/AP consistency choices. Its annual self-managed price is quote-only, so get a quote before comparing total cost with a Redis deployment.
What are Redis Free and Pro’s main limits?
Redis Free lists 30 MB, one database, shared cloud deployment, a best-effort SLA, and community support. Pro lists a $200 monthly minimum, unlimited RAM, multiple databases, active-active multi-region, and up to 99.999% uptime. The pricing information also says the first $200 is free.
