chromem-go

High-performance Java library providing SDK functions for vector search with HNSW-based ANN, supporting async indexing via IndexWriter futures, batch document ingestion, and configurable dimensions up to 1024+. Ideal for Java app integration, LangChain via wrappers, offering finer control and lower latency vs native REST APIs of cloud vector DBs.

macOS desktop client library/app for ChromaDB with GUI for managing collections and embeddings. Features batch operations, real-time queries, and direct integration without heavy API reliance. Suited for app development workflows and LangChain debugging; simpler than raw Python/JS SDKs for visual exploration.

Go SDK (chroma-go) client library for ChromaDB with async goroutine-based queries, batch collection creation/ingest via HNSW config, in-process persistence. Enables Go app integration and LangChain workflows; offers native speed and type-safety vs Python/JS HTTP clients or native REST APIs.

Python library (chroma-hnswlib) fork of hnswlib for ChromaDB indexing with async batch vector ingest, HNSW param tuning (ef_construction/search). Core for Python/JS app embedding pipelines and LangChain; faster in-process ANN vs remote API calls to vector DBs.

Python SDK from Meta for dense passage retrieval using dual BERT encoders and FAISS indexing, supporting batch embedding generation, async queries via multiprocessing. Enables Python/JS app Q&A pipelines and LangChain retrievers; 9-19% better accuracy than BM25 lexical APIs.

Python SDK for multi-modal Document handling with serialization, batch transport via DocList/DocVec, async processing with Pydantic validation. Suited for Python/JS/Rust app integration, LangChain document loaders; more structured than raw tensor APIs.
