Open Source LangGraph Projects

LangGraph is a framework for building stateful applications powered by language models. It represents workflows as graphs of steps and transitions, making it possible to coordinate model calls, tools, and human input. This approach helps developers manage branching logic, repeated actions, saved state, and long-running processes that are difficult to handle with a simple sequence of prompts. It is commonly used for AI agents and other applications that need explicit control over how tasks proceed.

Open source tools in this area include workflow templates, agent frameworks, debugging utilities, and deployment components. When choosing one, review its license, maintenance activity, documentation, runtime requirements, and compatibility with your models and services. Consider how it handles state, errors, observability, and human review. These tools can help developers and research teams prototype, inspect, and operate graph-based AI workflows.
