✓ Use when
Developers prototyping RAG applications and demos. The fastest vector DB to start with — no infra needed.
✗ Avoid when
Production workloads at >1M vectors with high QPS — Pinecone, Qdrant, or Weaviate are more battle-tested at scale.
What is Chroma?
Chroma is the developer-first open-source vector database. Run it in-memory during development with one `pip install` line, then scale to a managed cloud deployment without code changes. Popular for prototyping RAG apps and local AI demos. The simplest Pinecone alternative to get started with.
