Vector Databases in 2025: Pinecone vs Qdrant vs pgvector vs Weaviate
By Sayyed Abrar Akhtar • Published 2025-02-19
Benchmarking performance, filtering capabilities, self-hosting cost, and index types (HNSW vs IVFFlat).
Choosing the right vector database depends on scale and existing stack integration:
- **pgvector**: Best if you already run PostgreSQL and need unified transactional + vector data storage under 10M vectors.
- **Qdrant**: High-performance Rust-based engine with flexible payload filtering and easy self-hosting.
- **Pinecone**: Fully managed serverless vector database with instant auto-scaling.
