## What it is
A curated awesome-list of diagramming tools for software engineering teams, covering diagram-as-code and hand-drawn options like Mermaid, PlantUML, Excalidraw, and Draw.io. It categorizes tools by diagram type (architecture, sequence, ER, Gantt) and compares pricing, licensing, ease of use, and visual style.

## Use cases
- find a tool to draw system architecture diagrams
- compare diagram-as-code tools like mermaid and plantuml
- choose a diagramming tool for sequence diagrams
- find free open source alternatives to lucidchart
- pick a tool for database ER diagrams
- find hand-drawn style diagram tools like excalidraw

## When to choose
- you need to survey the diagramming tool landscape before picking one
- you want a quick comparison of pricing, licensing, and style across tools
- you are deciding between diagram-as-code and hand-drawn approaches

## When to avoid
- you need an actual diagramming tool rather than a list of them
- you need detailed tutorials or documentation for a specific tool
