HNSWLIB
Fast Approximate Nearest Neighbor Search
Apache-2.0
ABOUT
Vector similarity search at scale requires efficient approximate nearest neighbor (ANN) algorithms that balance speed, accuracy, and memory usage. HNSWlib provides a battle-tested, production-grade implementation of the HNSW algorithm — widely regarded as one of the best ANN methods — with a simple Python API. It is the underlying engine behind many vector databases and semantic search systems.
