Goblin Red Turns Agent Plans Into Executable Diagrams

Why it surfaced

Goblin Red treats the diagram as an executable plan: blocks hold Markdown specs, arrows encode order and branches, and live status appears directly on the canvas as agents work. It also offers Mermaid and JSON Canvas export, a plain HTTP API, and links designed for tools such as Claude Code, Codex, Cursor, and Gemini CLI.

A free, self-hosted flowchart editor lets people map AI-agent systems as diagrams that orchestrators can read and run.
