USearch
USearch is an open-source, high-performance similarity search and clustering engine for vectors and arbitrary objects. Distributed as a single-file C++11 library, it offers bindings for C, Python, JavaScript, Rust, Java, Objective-C, Swift, C, Go, and Wolfram, and runs on Linux, macOS, Windows, iOS, Android, and WebAssembly. It delivers an HNSW implementation reported to be significantly faster than FAISS while remaining simple and extensible. Key features include SIMD-optimized execution with JIT-compiled user-defined metrics, hardware-agnostic support for half-precision and quarter-precision types, memory-efficient uint40t point-clouds, and on-disk index serving without loading into RAM. It supports heterogeneous lookups, renaming, and on-the-fly deletions, plus binary Tanimoto and Sorensen coefficients suited to genomics and chemistry workloads. USearch is trusted by Google, ClickHouse, and DuckDB, and is commonly used for vector databases, recommendation systems, semantic search, molecular similarity, and
