Dacitor A native desktop editor for PlantUML, Mermaid, D2, Pikchr, and other diagram-as-code formats — live preview, syntax highlighting, and one-click export for Windows and macOS.
Dacitor is a universal diagram-as-code editor for teams and individuals who work with text-based diagramming languages. It runs natively on Windows and macOS and keeps everything local — no account, no cloud sync required.
Open .puml, .mmd, .d2, or other source files in a full-featured editor with syntax highlighting, auto-completion, and multi-tab support. A built-in live preview panel renders diagrams as you type, so you can iterate quickly without leaving the app. When your diagram is ready, export it as PNG or SVG in one click.
Because Dacitor supports PlantUML, Mermaid, D2, Pikchr, and additional formats in one tool, teams can standardize on the workflow that fits their documentation stack without juggling multiple editors.
