What you can use it for

Store embeddings and retrieve related documents for an AI application.

  • Extremely simple developer setup: run in-memory, local SQLite, or Docker container.
  • Native Python and JavaScript client libraries with built-in document embedding functions.
  • Perfect for local RAG pipelines and LLM context retrieval.
Workflow coverage and comparison notes

Store and query document embeddings locally or self-hosted using open-source Chroma instead of Astra DB Vector.

Before you switch

Optimized primarily for single-node deployments; massive multi-billion vector scale requires distributed orchestration.
