Prerequisites

• LangSmith
• Agent Server
• LangGraph CLI

Studio is a specialized agent IDE that enables visualization, interaction, and debugging of agentic systems that implement the Agent Server API protocol. Studio also integrates with tracing, evaluation, and prompt engineering.

Features#

Key features of Studio:

• Visualize your graph architecture
• Run and interact with your agent
• Manage assistants
• Manage threads
• Iterate on prompts
• Run experiments over a dataset
• Manage long term memory
• Debug agent state via time travel

    end

Studio works for graphs that are deployed on LangSmith or for graphs that are running locally via the Agent Server.

Studio supports two modes:

Graph mode#

Graph mode exposes the full feature-set and is useful when you would like as many details about the execution of your agent, including the nodes traversed, intermediate states, and LangSmith integrations (such as adding to datasets and playground).

Chat mode#

Chat mode is a simpler UI for iterating on and testing chat-specific agents. It is useful for business users and those who want to test overall agent behavior. Chat mode is only supported for graph’s whose state includes or extends MessagesState.
