Weaviate
Open-source vector database with an always-free cluster tier and hybrid search included on every plan.
- Vector databases
- Yes
- Flex tier starts at $45/month, pay-as-you-go, no commitment.
- Free and Flex tiers run on AWS and GCP with limited regions (2 and 7 respectively). Premium dedicated runs on GCP, AWS and Azure across roughly 40 regions.
Who it suits.
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.
Consider something else if…
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.
