Sketch

Sketch is a digital design platform focused on interface, web, and product design. It provides a vector-based canvas and a structured workflow for creating, prototyping, and handing off UI and UX designs. Built specifically for macOS with collaborative tools in the browser, Sketch supports the full design lifecycle from early concepts to developer-ready deliverables.

Key features include powerful vector editing tools, reusable Symbols and Components, and shared Libraries that keep design systems consistent across teams. Designers can create responsive layouts using flexible resizing, constraints, and grids, and preview work on real devices. Sketch also offers built-in prototyping, allowing users to link artboards, define interactions, and share interactive prototypes via the web. Developer handoff is supported through inspect tools, downloadable assets, and design specifications accessible in the browser without requiring a Mac license.
