What It Does
Chroma is an open-source embedding database focused on developer simplicity. It makes it easy to store embeddings and their metadata, search by similarity, and build AI applications with retrieval — all with a minimal, intuitive API.
Key Features
- Simple API — get started in 4 lines of code
- In-process — runs embedded in your application (no separate server needed)
- Automatic embedding — built-in support for popular embedding models
- Metadata filtering — filter results by any metadata field
- Multi-modal — store and query text, images, and audio embeddings
- Open source — Apache 2.0 license, fully transparent
- Client/server mode — scale to production with server deployment

Who It’s For
Developers prototyping AI applications, teams wanting the simplest possible vector storage, and anyone building RAG systems who values developer experience over operational features.
Competitive Position
Chroma wins on simplicity and developer experience — it is the easiest vector database to get started with. The in-process mode means no infrastructure for prototypes. However, it trails Pinecone and Weaviate on production-scale features (multi-tenancy, managed operations). Popular choice for prototyping that often gets replaced by Pinecone/Weaviate in production at scale.
