pgvector-crystal

Official .NET SDK/client (C#/F#) for pgvector, supporting async vector insert/query with HNSW/IVF indexes over Postgres. Integrates with Npgsql, Dapper, Entity Framework for type-safe operations. Suited for enterprise .NET app integration in RAG/semantic search; official bindings vs. community or direct SQL.

JavaScript/TypeScript SDK/client (Node.js/Deno/Bun) for pgvector PostgreSQL extension, enabling async vector storage and similarity queries. Supports REST-like ops via pg driver, Prisma integration. For JS app integration in RAG/semantic search; official bindings vs. direct SQL or other SDKs.

COBOL bindings and examples for pgvector, letting legacy COBOL systems interact with PostgreSQL as a vector database.

pgvector-elixir is the Elixir client for pgvector, allowing vector similarity search and operations from Elixir/Phoenix apps connected to Postgres. Supports Ecto integration for seamless queries with HNSW/IVF indexes and distance metrics. Ideal for functional web apps with semantic search; extends pgvector ecosystem to Elixir BEAM VM, offering concurrent high-throughput vs. single-threaded clients.

Node.js bindings (JavaScript/TypeScript SDK) for HNSWLib C++ library, enabling fast ANN vector search with async operations and V8 optimization. Supports L2/cosine distances, file persistence, filtering, and LangChain integration for seamless app embedding. Ideal for web/serverless JS RAG; lighter JS alternative to Python hnswlib bindings vs. full vector DBs like Chroma.

Managed PostgreSQL with pgvector for AI workloads, featuring HNSW indexing and embedding search.
