OmniGraffle
OmniGraffle is a macOS diagramming and vector graphics app for creating flowcharts, wireframes, layouts, and other precise visual documents.
What is OmniGraffle?
OmniGraffle is a native Mac diagramming and vector graphics application that helps people turn ideas, systems, and plans into clear visual documents. It is used for flowcharts, process maps, org charts, wireframes, network diagrams, floor plans, and other structured graphics where alignment and precision matter. The app includes drawing tools, snapping and alignment controls, reusable stencils, layers, and canvas management to support both quick sketches and polished deliverables. It also supports rapid prototyping and visual communication workflows for designers, technical teams, educators, and business users who need to explain complex information clearly. OmniGraffle is published by The Omni Group and is also available on iPhone and iPad for users who want to work across Apple devices.

Safety overview
Status: Safe
OmniGraffle is legitimate productivity and design software for macOS. It normally works with documents you create or open, so the main privacy consideration is the content stored in your diagrams and any files you choose to import, export, or sync. Its file access and document handling are ordinary for a diagramming app. Keep the app updated, especially if you open files from other people, since document-based apps can occasionally receive security fixes for file parsing issues.
Recommendation: Keep OmniGraffle if you use it for diagrams, wireframes, or technical visuals on your Mac. If you no longer use it, you can remove it like other Mac apps, but save any project files you still need first because uninstalling the app will not help you edit those documents later.
