VizLang - Speedup your Agent Development

VizLang reimagines agent debugging by providing a visual, interactive environment directly within VS Code. Key features include: * Real-time graph visualization of agent execution * Step-by-step decision inspection * Integrated chat for direct agent interaction * Human-in-the-loop interrupt management * Full state inspection on node hover This open-source visual debugger helps developers understand complex LangGraph agent workflows by making the execution flow transparent. Instead of relying on print statements, users can watch nodes light up as they execute, observe data flow through animated edges, and identify exactly where issues occur. The intuitive interface allows for zooming, dragging, and auto-layout of the agent's architecture, providing an immediate visual understanding of its structure. VizLang empowers developers to pause execution after each node to inspect the complete state snapshot, then step forward or allow the agent to continue. It also offers a seamless chat experience to interact with agents, send messages, and view streaming responses and tool calls, even supporting multimodal agents with image and file attachments. All functionality runs locally, ensuring privacy and eliminating the need for cloud accounts, API keys, or internet connectivity. Designed for individual developers and teams building LangGraph agents, VizLang streamlines the development and debugging process for complex, conditional, and tool-using agents. It serves as an essential tool for rapid iteration and ensures robust agent performance.
