Axure vs Omnigraffle
Create Prototypes of Websites & Apps Without Coding. Axure RP gives you the wireframing, prototyping and specification tools needed to make informed design choices, persuade any skeptics, get your design built to spec... and maybe win a few fans along the way. Choose the Standard edition for prototyping or go Pro to add documentation and collaboration features.
OmniGraffle can help you make eye-popping graphic documents—quickly—by providing powerful styling tools, keeping lines connected to shapes even when they’re moved, and magically organizing diagrams with just one click. Create flow charts, diagrams, UI and UX interactions, and more. Whether you need a quick sketch or an epic technical figure, OmniGraffle and OmniGraffle Pro keep it gorgeously understandable.
