Sketch

Sketch is a complete design toolkit for creating interfaces, prototypes, design systems, and visual product workflows. It combines a native macOS app for design and prototyping with web-based tools for sharing, feedback, version history, and developer handoff.

Designers can use Sketch to create layouts, manage components and shared libraries, build interactive prototypes, collaborate in real time, and hand off designs to developers. The platform also supports local files, offline work, flexible stack layouts, color profile control, OpenType and variable fonts, and free viewers for reviewing designs.

Sketch offers subscriptions for collaboration-focused teams, as well as a Mac-only license for users who want to work offline with the native app through a one-time purchase.
