Our Verdict
Chroma is the default on-ramp to vector search for most developers: install it, feed it documents, and a RAG prototype is running in minutes — no infrastructure, no embedding pipeline to wire up. The in-process design and first-class LangChain and LlamaIndex integrations make it ideal for local development and iteration. Once you need horizontal scale, multi-node replication, or heavy metadata filtering at millions of vectors, heavier engines pull ahead. Start here, and migrate when the data says so.
