langchain-ai/langchain and crewAIInc/crewAI are leading frameworks; for learning agent design, study AutoGPT and the agents examples in these repos.
Pick one framework (LangChain or CrewAI), follow its examples, and build a small tool-using agent before moving to multi-agent setups.
Yes — the frameworks are open source. You only pay for the underlying model/API usage if you use a paid provider.
Pair these with our learning roadmaps, free courses, and notes library.
