Sketch is a native macOS app for interface design and prototyping, paired with a web app for sharing, feedback and handoff. It's made for designers who want a focused Mac tool that works offline or with a team.

Key features:

Build screens with nestable frames and stack layouts that adapt to their content.
Draw icons and interfaces with a precise vector editor.
Turn designs into prototypes with Smart Animate, overlays and scroll areas, then test them in a browser or on iPhone and iPad.
Share Libraries, styles and components to keep designs consistent.
Work locally and offline, or co-edit with others in real time.
Invite developers to inspect files, download assets and export tokens for free.
Connect Claude, Cursor or another MCP client to your designs.

Sketch requires macOS Sequoia (15.0) or later and is available directly or from the Mac App Store. After a 30-day free trial, the Standard plan costs €11 per editor per month billed yearly, or you can buy a Mac-only license for €108 per seat with a year of updates. The free Sketch View and Mirror app plays prototypes on iPhone and iPad.
