- **Diagram-as-code (Mermaid/PlantUML)** — 2 of 7 apps with a verified answer have this

## Overview

- **Who it's for**: Individuals and teams who need free, no-lock-in diagramming for flowcharts, UML, ERDs, network/cloud architecture, and technical documentation, including privacy-conscious users and organizations already living in Confluence, Jira, Google Drive, or Microsoft 365.
- **What you get**: A full-featured, Apache-2.0 open-source diagram editor with extensive shape libraries and templates for flowcharts, UML, ER diagrams, network and cloud architecture, plus Mermaid/PlantUML text-to-diagram, CSV-to-diagram generation, Claude-powered AI diagram generation, Visio (.vsdx) import, and export to SVG/PNG/PDF/HTML.
- **How it works**: Runs as a free browser-based editor (app.diagrams.net) or offline desktop app for Windows/macOS/Linux, storing diagram files wherever you choose (device, Google Drive, OneDrive, Dropbox, GitHub) rather than on draw.io's own servers; real-time co-editing with shared cursors is available when files are stored on supported backends like Google Drive, OneDrive, or Confluence Cloud.
