USearch is a Smaller & Faster Single-File Vector Search Engine.
USearch's base functionality is identical to FAISS, and the interface should look familiar if you have ever investigated Approximate Nearest Neighbors search. USearch and FAISS both employ HNSW algorithm, but they differ significantly in their design principles. USearch is compact and broadly compatible with FAISS without sacrificing performance, with a primary focus on user-defined metrics and fewer dependencies.
