agenttrail
agenttrail is a local observability tool for AI coding agents that watches project files and agent activity and turns them into two live views: a project structure map and a 3D task-and-role visualization.
agenttrail gives visibility into what AI coding agents such as Codex and Claude Code are doing, without piecing together several terminal windows. It watches local files, plans and supported agent events, then visualizes that evidence; it does not run the agents, assign their work, or decide when a task is finished.
The project has two views. Agenttrail Map shows project structure, progress and which components are changing, sourced from a PLAN.md file, file changes and optional Claude Code hooks, started with npx agenttrail. Agenttrail Kitchen visualizes current tasks, role contributions and completed work as a 3D scene of chefs, order tickets and deliveries, sourced from native agent todos and optional hooks, started with npx agenttrail-kitchen.
Each view runs independently in the browser with its own local service, requires Node.js 20+ and a WebGL-capable browser, and needs no API key for basic use.
