Sketch
Native Mac app for UI and app design
Sketch is a vector design tool for interfaces that runs as a native app on the Mac. Files live in the cloud, teams collaborate in real time, and developers can inspect measurements, assets and versions in the browser without a licence of their own. If you would rather avoid a subscription, a Mac-only licence is a one-time purchase that leaves out collaboration.
Why it made the cut- A native macOS app, not a browser wrapper
- Unlimited free viewers on the web
- One-time purchase as an alternative to subscribing
