Agno – Super clean dev experience (friendly for most devs)
AutoGen – Chat-based agent research (ideal for R&D and convos)
CrewAI – Fast way to build agents that work together (great for prototyping)
A classic RAG (Retrieval-Augmented Generation) setup built on LangChain. If your agents need some receipts (a.k.a. context), this one's your go-to.
LangGraph – Handles complex workflows (good for nerdy/structured stuff)
PydanticAI – Type-safe agents (you won't break things easily)
SmolAgents – Minimalistic, lightweight (perfect for side projects); gives colorized diagnostics.
