Chroma is an open-source embedding database designed for AI applications. It's the simplest vector database to get started with—pip install chromadb and you're running. Perfect for prototyping RAG applications and local development.

Is Chroma good for production?

Chroma works for small-to-medium production workloads. For large-scale production (millions of vectors, high QPS), consider Pinecone or Weaviate. Chroma's strength is developer experience and ease of integration with LangChain and LlamaIndex.

How does Chroma compare to Pinecone and Weaviate?

Chroma: simplest setup, best for prototyping, open source. Pinecone: best managed service, easiest scaling. Weaviate: best hybrid search, self-hostable with advanced features. Start with Chroma, migrate to Pinecone/Weaviate when you need scale.

How do I get started with Chroma?

pip install chromadb, then: client = chromadb.Client(); collection = client.create_collection("docs"); collection.add(documents=["text"], ids=["id1"]); results = collection.query(query_texts=["search"]). That's it—no server setup needed.

Does Chroma generate embeddings automatically?

Yes. By default, Chroma uses a local embedding model (sentence-transformers). You can also configure OpenAI, Cohere, or custom embedding functions. For production, specify your embedding function explicitly for consistency.

Can I persist Chroma data?

Yes. Use chromadb.PersistentClient(path="./db") for persistent storage. In-memory mode (chromadb.Client()) is great for testing but loses data on restart. Persistent mode saves to disk automatically.

Does Chroma support metadata filtering?

Yes. Store metadata with documents and filter during queries: collection.query(query_texts=["search"], where={"category": "tech"}). Supports $eq, $ne, $gt, $lt, $in, $nin operators for flexible filtering.
