Redis Cloud vs Weaviate

SEPT 2026 audit

A comparison of Redis Cloud and Weaviate built from values read directly from each provider's own documentation, with the source recorded against every figure.

Reviewed by Palash BagchiUpdated 28 criteria comparedSources last checked

The short answer

Choose Redis Cloud if…

Teams that want Redis from the company that maintains it, with an on-demand hourly Essentials tier cheap enough to run a small production workload without committing to a fixed plan.

Editorial · Palash Bagchi · approved

Choose Weaviate if…

Teams that want hybrid search included on every tier without an add-on, or that want an always-free cluster (not a time-limited trial) to build against before committing to a paid plan.

Editorial · Palash Bagchi · approved

Consider something else if…

  • Redis Cloud: Multi-region active-active replication is needed on a small budget — that's a Pro-tier feature here, where a serverless competitor may price per-region replication into a lower-cost plan.
  • Weaviate: Predictable flat pricing matters more than granular control — per-dimension consumption billing means cost scales with embedding choices in a way a flat per-month plan doesn't.

Documented by only one.

These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.

What the free plan includesWeaviate: One fully managed cluster per user, free forever and with no credit card, upgradable to paid at any time.
Credit card to startWeaviate: No
When the free offer endsWeaviate: Never — the Engram tier is billed $0/mo, free forever.
Uptime SLAWeaviate: Best effort on Free; 99.5% on Flex; 99.9% on Premium shared; 99.95% on Premium dedicated.
Max dataset size, entry planRedis Cloud: 30 MB on the free Redis Cloud Essentials plan; paid Essentials plans start at 250 MB and run to 12 GB, or to 100 GB on the Essentials plans with Redis Flex, per the plan tables on this page. Redis Cloud Pro is separate: the plan comparison lists 50 TB memory size.
Data persistenceRedis Cloud: AOF (every write on Redis Cloud Pro, every second on paid Essentials) or snapshots every 1, 6 or 12 hours; free Essentials plans support no persistence at all.
Multi-region replicationRedis Cloud: Active-active multi-region replication is a Pro feature, alongside auto-tiering and private connectivity; Essentials is active-passive.
Max vector dimensionsWeaviate: 65,535 dimensions maximum per embedding vector in Weaviate Database, because the embedding is stored using uint16. Stated for Weaviate Database generally; the FAQ gives no separate Weaviate Cloud cap.
Hybrid search (vector + keyword)Weaviate: Supported across all plans.
Response time commitmentWeaviate: Severity 1: none on Free, one business day on Flex, 4 hours on Premium shared, 1 hour on Premium dedicated. No comparable number, because a business day is not a fixed span.
PCI DSSRedis Cloud: Assessed as a Level 1 Service Provider against PCI DSS 4.0.1; Redis Cloud Flexible/Annual subscriptions may process, store and transmit card data. Scope named as Redis Cloud Flexible/Annual subscriptions, not Essentials.
Customer-managed keysWeaviate: Encrypted volumes with customer keys listed only for the Premium dedicated plan; not available on Free, Flex or Premium shared. Plan table columns are Free, Flex, Premium shared, Premium dedicated.
