Sketch is a design toolkit for digital products. Its core is a vector editor for macOS that also works offline, with stack layouts, nestable frames, templates and component libraries. It also offers prototyping with animations and interactions, an iOS app for viewing designs, prototypes that can be tested in a browser, and collaboration with shared workspaces, comments and co-editing. Developers can inspect files and export assets. The product combines an installed app with cloud services.
