ChromaDB

ChromaDB is an open-source embedding database designed for simplicity and ease of use in AI applications. It provides a Python-first API for storing, querying, and filtering vector embeddings with minimal setup — just pip install and go. ChromaDB supports in-memory storage for development, persistent storage for production, and includes built-in document embedding using default models. While not designed for billion-scale deployments, ChromaDB excels as a lightweight solution for prototyping, small to medium RAG applications, and local development.
