LangGraph
✓ VerifiedGraph-based framework for controllable, stateful AI agents
About
LangGraph is an open-source framework in the LangChain ecosystem for building stateful, multi-step agents with controllable graphs (single, multi-agent, hierarchical flows). It supports human-in-the-loop interrupts, streaming, memory, and tool use, and can be deployed via LangGraph Platform or self-hosted OSS.
Key Features
- ✓Graph-based agent architecture (single, multi-agent, hierarchical)
- ✓Stateful execution with memory and persistence
- ✓Branching and conditional control flows
- ✓Tool use and streaming of intermediate steps
- ✓Human-in-the-loop interrupts and rollbacks
- ✓Deploy via LangGraph Platform or self-host
