Our take
Pick LangChain if engineers building agents in Python or JS who will read traces when something breaks. Pick Mem0 if agent builders who want a managed memory store and will stay inside the monthly add/retrieve caps. Skip LangChain if no-code ops teams (Zapier / Make) or people who only want a visual canvas (Langflow / Dify).
