CrewAI - A Solid Framework, but Not Recommended For Beginners
CrewAI is a solid framework for building agent crews. The concept behind it is clever, with the core idea being that you organize your work into separate tasks people complete like an assembly line.
However, it abstracts quite a bit of the process for you, especially if you utilize pre-build tools or LangChain plugins. For those looking to learn, I would highly recommend working through the MCP tutorials provided by Anthropic and build your own agent from scratch or utilize a more bare metal style framework like MCP-Agent.
