Who it's for

Professional and freelance UI/UX designers working on macOS, from independent designers to product teams at larger companies who need a dedicated interface design tool.

What you get

A native vector editor for designing screens and components, with reusable styles, symbols/components and shared libraries for maintaining design systems. Built-in prototyping lets you link screens, add transitions and simulate interactions for testing on web, iOS and iPad. The companion web app adds real-time co-editing, commenting, version history and developer handoff (inspect, export assets, copy CSS/code specs).

How it works

You design and prototype in the native Mac app, building screens from vector shapes, components and shared styles. Files sync to Sketch's cloud Workspaces, where teammates can co-edit, comment, and view or inspect the work in a browser, and developers can pull measurements and assets directly from the shared file.
