Sketch

Sketch is a digital design toolkit built for creating user interfaces, websites, and icons, primarily used by product designers and UX/UI teams. It offers a native macOS app alongside a browser-based web app, allowing collaboration across platforms without requiring all users to be on Mac. The tool centers on vector editing, reusable components, and symbols that help maintain design consistency across large projects. It supports collaborative features such as shared libraries, cloud document storage, and developer handoff tools that generate specs and assets directly from design files. Sketch integrates with plugins and third-party services to extend functionality for prototyping, version control, and workflow management within design teams.
