What Is Weaviate?
Weaviate is an open-source vector database for AI search, with a managed cloud service. Self-hosted Weaviate is described as free under the BSD-3 licence in the sources I found, so you pay only for infrastructure, though I did not check the repository directly. For the cloud, none of the sources is Weaviate's own pricing page. Flex is the entry paid plan with a $45 a month minimum on shared cloud and a 99.5% SLA. Plus is listed at $280 a month on annual billing with a 99.9% SLA and SOC 2. Premium is listed at $400 a month or more, with a 99.95% SLA, dedicated or bring-your-own-cloud deployment and HIPAA, though one source calls Premium pricing custom. The free option is a 14-day sandbox, not a permanent plan.
One source says Weaviate restructured pricing in October 2025, moving from a simple per-dimension model to three billing dimensions: vector dimensions, object storage and backup storage. The Premium rate is consistently $0.00975 per million dimensions per month, but the Flex rate varies between $0.01668, $0.0139 and $0.00465 before compression discounts, and I could not tell which is current. A blog on replication also warns that costs scale with the replication factor. Because of the spread, run the official calculator before committing.
Weaviate suits teams that want hybrid search and the flexibility to self-host or use a managed cloud. Compare Pinecone, Qdrant and Chroma. Browse the MLOps & Infrastructure tools directory for more.
