- For
- Developers and systems modelers who write diagrams in text formats
- Worth noticing
- The page says its Content Security Policy sets connect-src 'none'; each format’s renderer must be loaded before offline use.
Field notes
The page lays out three ways to check its local-processing claim: inspect the stated browser policy, try drawing offline after loading a format, or read the shipped JavaScript. Its conversion example identifies losses by line number, including PlantUML styling and a phase separator. The SysML v2 implementation is limited to a practical structure-view subset, while draw.io files receive a simplified preview and remain editable in draw.io.
