The honest brief
CrewAI
Models work as a crew of role-typed agents that delegate to each other, built standalone rather than on LangChain.
- Role-based multi-agent model
- Independent of LangChain
- Model-agnostic
- Good for research pipelines
- Opinionated structure
- Less flexible than graph frameworks
- Debugging multi-agent runs is hard
Haystack
More production-oriented and explicitly composable than lighter agent libraries: typed pipelines give direct control over retrieval, routing, and memory.
- Composable, typed pipeline architecture
- Model- and vector-store agnostic
- Strong production tooling
- Mature docs and integrations
- Pipeline model has a learning curve
- Python-only
- Heavier than minimal agent libraries
