The short answer

- 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.
- Pick 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.

- Redis Cloud: Essentials: from $0.007/hour, $5/month total. 250 MB-100 GB RAM and SSD, single DB.

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.
