Best For
AI-native developer experience — the fastest path from `pip install` to a working RAG prototype, with a managed cloud when you're ready
Teams already running Postgres who want vector search without adding a new database — ACID, joins, and one operational story
Limitations
Younger than Pinecone or Weaviate at scale; fewer index tuning knobs (HNSW only); compliance certifications are still maturing
Slower at scale than purpose-built engines; no native multi-tenancy primitives beyond schemas; hybrid search and serverless depend on the host platform (Supabase, Neon, etc.), not pgvector itself
