Studio

See your graph think.

A visual debugger that mounts on top of any running Agentmatic agent. Step through supersteps, inspect state diffs, branch from any checkpoint. Open-source, self-hosted.

What it does

• Graph visualization — nodes, edges, conditional routes rendered as a force-directed diagram.
• Step debugger — pause before any node; inspect inputs, outputs, and state diffs; resume.
• Checkpoint timeline — scrubbable history of every superstep, with branch-from-here.
• Tool call inspector — every LLM call, every tool invocation, with prompts and raw responses.
• State diff viewer — diff between any two checkpoints, JSON-friendly.

Run it

pip install agentmatic-studio
agentmatic-studio serve  # http://localhost:7860

Then attach your agent:

from agentmatic.studio import attach

agent = Agent.builder("debug").llm(OpenAI()).tools([...]).build()
attach(agent, port=7860)  # opens Studio in browser
await agent.ainvoke(...)

Compared to LangGraph Studio

• Open source. Apache-2.0, self-hosted, no SaaS dependency.
• Local-first. All state stays on your machine.
• Multi-language. Attaches to Python, TS, Rust, Go, and Java agents over the same gRPC interface.
