Pros & cons
CrewAI
Pros
- Intuitive role-based multi-agent model
- Fast to prototype with
- Active community and growing ecosystem
- Open-source core
Cons
- Multi-agent systems are hard to evaluate and debug
- Less low-level control than LangGraph
- Production hardening is on you
Semantic Kernel
Pros
- First-class C#, Python, and Java support
- Designed to fit into existing enterprise apps
- Backed and maintained by Microsoft
- Clean plugin and function abstractions
Cons
- Smaller ecosystem than Python-first frameworks
- Roadmap is converging with Microsoft Agent Framework
- Less suited to rapid Python prototyping
Which should you choose?
Semantic Kernel is the lighter-weight option (Free), while CrewAI sits higher on the pricing ladder (Freemium). CrewAI is built around teams prototyping multi-agent workflows; Semantic Kernel leans more toward .net and java enterprise development teams. Shortlist the one whose strengths line up with your biggest constraint.
