LangChain is an open-source framework for building applications and agents on top of language models, with integrations for many model providers and tools. Its companion LangGraph runs agents as graphs of steps with saved state, so a workflow can pause, resume and survive failures. LangGraph's interrupts let a workflow stop for a person to approve or edit a step before it continues. When comparing these listings, check whether long-running agent work is resumable and where a person can intervene.
