CriteriaPineconeWeaviate
Setup ComplexityMinimal — fully managed, no config requiredModerate — YAML schema required, module selection needed
Cost at 1M Vectors~$70/mo (Starter)~$25/mo serverless; free if self-hosted
Query Latency~5-20ms p99~5-25ms p99 (varies by module overhead)
Hybrid SearchSparse-dense (preview)Mature BM25 + vector hybrid out of the box
Scaling CeilingBillions of vectors, auto-scalingBillions of vectors; multi-tenancy native support

The Verdict

Weaviate's standout advantage is its built-in hybrid search combining BM25 keyword scoring with vector similarity, plus a rich module ecosystem that can auto-vectorize data at ingest.
