Why I built my own PlantUML Generator (and why you might need it too)

If you're a developer, chances are you've used PlantUML or Mermaid to visualize logic. While Mermaid is great for quick charts, many enterprise projects still require PlantUML. However, the developer experience (DX) with PlantUML isn't always smooth. After struggling with slow rendering and clunky previews, I decided to build a web-based, offline-capable PlantUML generator. The Motivation The biggest "pain point" for me was the setup. Most solutions require a portable PlantUML server or a heavy VS Code extension. I wanted something fast, lightweight, and accessible directly in the browser—even without an internet connection. Solving the "Pain Points" I built Beautiful PlantUML to solve 5 specific issues I faced daily: Sticky Participants: In large diagrams, scrolling down means losing track of which line belongs to which participant. I made them "sticky" so you always have context. Flexible Zooming: Instead of fighting with VS Code’s scroll-zoom, I implemented a more fluid navigation s
