Pladitor A dedicated PlantUML editor for Windows and Mac — write diagrams with auto-completion, see them render instantly, and export to PNG, SVG, or shareable links.
Pladitor is a focused PlantUML editor for Windows and macOS. It turns PlantUML source text into rendered diagrams in real time, so you can write and refine diagram code without manually triggering a rebuild.
The native desktop app includes a full-featured code editor with PlantUML syntax highlighting and auto-completion, a live side-by-side preview panel, multi-tab document management, and a built-in library of diagram templates. Export finished work as PNG or SVG for documentation, presentations, and version control. The import feature lets you recover PlantUML source embedded in an existing PNG or SVG — useful when the original source file is no longer available.
Pladitor runs entirely on your machine. There is no cloud account or subscription required for the core editing workflow.

Features
Focused PlantUML workflow
Write PlantUML diagrams in a native editor built around PlantUML syntax — auto-completion, highlighting, keyboard shortcuts, and multi-tab editing keep the workflow fast.
Live preview, import, and export
See your diagram update as you type, import code embedded in PNG or SVG files, and export finished diagrams in multiple formats for docs, slides, and wikis.
Templates and built-in guides
Start from a library of built-in templates covering sequence, class, activity, and other PlantUML diagram types — useful for quick starts and team standardization.
