Build AI Agents Visually.
Open-source platform for LangChain & LangGraph workflows. Drop agents on a canvas, connect them, deploy.
Making agentic AI accessible.
From idea to working agent is too many steps.
Graph definitions, state management, prompt engineering, tool integration. By the time you've wired it all together, you've lost the idea.
LangConfig gives you a visual canvas. Drop agents, connect workflows, watch them think in real-time. Export production-ready code when you're done.
Watch Agents Think
Tool selection, reasoning, and outputs stream live. Debug by seeing, not reading logs.
- Live execution streaming
- Visual error detection
- Interactive tool inspection
Canvas to Production
Export as a Python package with Streamlit UI, or share as JSON anyone can import.
- One-click Python export
- Streamlit UI included
- JSON configuration sharing
Your Data Stays Yours
Runs entirely local. Use your own API keys or local LLMs. No cloud dependencies. No data leaves your machine.
Built on LangChain & LangGraph
Not a black box—LangConfig generates real LangChain code. Eject anytime. You're never locked in.
Works with your models

About
LangConfig is built by Cade Russell at Ghost Peony LLC. The goal is straightforward: make multi-agent AI systems accessible to everyone, whether you're a developer prototyping your next idea or someone exploring agentic AI for the first time.
LangConfig exists to lower the barrier. Build visually, learn by doing, and ship when you're ready.
