- Minimal setup and clean Python API
- Open-source with a managed cloud option
- Ideal for prototyping and validation
Cons
- Production scale may warrant a heavier vector store

Unstructured
Pros
- Purpose-built for messy real-world documents
- Handles PDFs, tables, scans, and many formats
- Connectors for common enterprise data sources
- Open-source or managed API
Cons
- Complex document extraction is never perfect
- Managed API costs scale with document volume
- One stage of the pipeline — not end-to-end RAG
Which should you choose?
Chroma is built around teams prototyping rag and retrieval quickly; Unstructured leans more toward enterprises building rag over real document sets. Shortlist the one whose strengths line up with your biggest constraint.
