Weaviate
multi-tenancy and hybrid search, priced per million dimensions
the strongest combination of hybrid search and per-tenant isolation here — with a pricing model that punishes large embeddings in a way no competitor's does.
tenants are a native primitive, implemented as isolated shards, with cold-tenant offloading. for a saas product where each customer's documents must not leak into another's results, that is the feature that decides it, and building the equivalent on postgres is genuinely unpleasant at five figures of tenants.
hybrid search is first-class — bm25 and dense fused with configurable strategies — and the documentation is among the best in the category.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
