Vector Database Selection Report — Choose the Right Vector Store

I will assess your use case and deliver a written vector database selection report — comparing Pinecone, Weaviate, Chroma, Qdrant, Milvus, pgvector, and FAISS against your specific requirements across scale, hosting model, query performance, metadata filtering capability, and total cost of ownership. Vector database selection without systematic evaluation produces expensive lock-in — Pinecone's managed service is convenient but expensive at scale, pgvector's Postgres integration is compelling but has query performance limits, and FAISS is highly performant for batch search but requires infrastructure management that managed solutions eliminate; the right choice depends on your specific scale, budget, and operational constraints.

The report covers your scale requirements, hosting model preference, query performance needs, metadata filtering requirements, managed vs. self-hosted tradeoffs, and a clear recommendation with TCO analysis.
