Chroma vs Weaviate: what is the difference?

Chroma is freemium — a usable free tier with paid plans above it and is listed for fully open-source embedded/self-hosted vector store, the default choice bundled into countless RAG tutorials and frameworks.

Both sit in Vector Databases & RAG Infra.

Is Chroma or Weaviate cheaper to start with?

Neither — Chroma and Weaviate are both freemium, so the choice comes down to capability rather than cost. Both entries list what they uniquely do above.
