PlatformWebfreemiumglobal

Chroma is an open-source vector database for storing and retrieving embeddings, providing fast semantic similarity queries, metadata filtering, and support for OpenAI, Sentence Transformers, or custom embedding functions. It helps teams avoid building semantic search from scratch by offering local, in-memory, or persistent deployments with native Python and JavaScript clients, aimed at AI/ML developers building chatbots, retrieval-augmented generation systems, or recommendation engines.
