Best AI Agent Frameworks in 2025

AIResearcher

Let's discuss the top AI agent frameworks this year!

LangChain: Great ecosystem, extensive tools
AutoGen: Microsoft-backed, multi-agent conversations
CrewAI: Simple setup, role-based agents

Which do you prefer and why?

Great comparison! I'd add Haystack to the list - excellent for RAG implementations.

Also been experimenting with LlamaIndex recently. The query engine is incredibly powerful for document-based agents.

Performance-wise: LangChain has more overhead but better ecosystem. AutoGen is faster for multi-agent conversations.

From a production perspective, I've deployed all three:

LangChain: Battle-tested, great for complex workflows
AutoGen: Best for conversational agents
CrewAI: Easiest to get started, good for simple use cases

My team uses LangChain for 80% of projects. The debugging tools are essential.

CloudArchitect

Don't sleep on Semantic Kernel from Microsoft! If you're in a .NET environment, it's fantastic.

Also, LangGraph is becoming my go-to for complex state machines. Much cleaner than traditional LangChain chains.
