Moxie Docs Free Mermaid Diagram Editor

Overview

Moxie Docs has released a free Mermaid Diagram Editor that allows developers to create technical diagrams using the Mermaid.js syntax. The tool is designed for speed, privacy, and seamless integration into documentation workflows, providing a live preview and instant export options without requiring user accounts or installations.

Key Features

Live Rendering and Export

The editor provides a instant live preview where changes to the Mermaid syntax on the left side of the screen update the rendering on the right side in real-time. Users can download diagrams as high-resolution PNGs or clean SVGs, making them suitable for integration into READMEs, Notion, Confluence, and Google Docs.

URL-Based Collaboration

Collaboration is handled via URL query parameters. The entire state of the diagram is encoded directly into the URL, allowing users to share a link that allows others to see the exact same diagram without the need for server-side storage or database records.

Privacy and Client-Side Processing

All diagram rendering and rendering processes run entirely within the user's browser. Diagrams do not leave the user's device, ensuring a privacy-first approach with zero tracking on the tool itself.

Supported Diagram Types

The editor utilizes the latest Mermaid renderer to support all core diagram types, including:

• Flowcharts and C4-style diagrams: Used for architecture and system design to explain service connections.

• Sequence Diagrams: Used for API and data flows to map request lifecycles.

• Sequence Diagrams: Used for data models and database schemas via ER diagrams and class diagrams.

• Gantt Charts and Mindmaps: Used for roadmaps, timelines, and onboarding processes.

• Other types: Including pie charts, state diagrams, and gitGraph.

Integration with Moxie Docs

While the editor is part of a larger ecosystem, the free editor remains standalone. For teams requiring automated documentation, Moxie Docs offers a service that connects to GitHub repositories to automatically generate architecture diagrams from source code and refresh them on every merge, ensuring that documentation remains current with the same codebase changes.
