LangGraph
An orchestration framework for stateful agent workflows, combining graph-based control flow with persistence, streaming and human-review steps.
About this listing
LangGraph lets developers describe an agent workflow using shared state, processing nodes and transitions between them. Deterministic application logic can be combined with model-driven steps, while persistence and streaming help applications manage longer-running interactions. The framework also supports interrupting a workflow for human input.
A typical implementation defines the state and node functions, connects the graph, compiles it, and then invokes or streams execution. The core software is MIT-licensed and can be used independently of a hosted deployment service. The Free classification refers to the library code; model calls, infrastructure and optional hosted services can have separate costs.
