What problem does it solve?

Mermaid diagrams provide a text-based way to quickly visualize software architecture, workflows, and data models, enabling living documentation that stays in sync with code.

Core Features & Use Cases

  • Supports multiple diagram types (class, sequence, flowchart, ERD, C4, state, and more) to cover architecture, APIs, data models, and processes.
  • Enables easy version-controlled diagrams by describing diagrams in text, which simplifies updates and collaboration.
  • Works across platforms (GitHub rendering, VS Code preview, Notion/Obsidian) and supports exporting diagrams for presentations.

Quick Start

Create your first Mermaid diagram by writing a simple flowchart with a start node, a process node, and an end node.
