LangGraph Studio

LangGraph Studio (now LangSmith Studio) is the specialized Integrated Development Environment (IDE) for building, visualizing, and debugging complex, stateful AI agents.

This is your control center for agentic applications: LangGraph Studio provides the first dedicated IDE for agent development (built on the LangGraph framework). It features a visual graph editor, allowing you to design complex agent workflows (nodes and edges) without getting lost in code. Key capabilities include real-time debugging, dynamic breakpoints, and human-in-the-loop functionality, letting you inspect and modify agent state mid-execution. Use it to rapidly prototype, iterate on prompts, and deploy reliable multi-agent systems, all integrated with the LangSmith platform.
