Overview
Sketch is a native macOS design application for creating interfaces, prototypes, illustrations, and reusable libraries. Its web app supports sharing, comments, permissions, browser-based inspection, and developer handoff, while teams can collaborate in shared Workspaces. It runs natively on macOS and offline. Sketch also documents an official MCP server that lets compatible AI clients inspect design files and use frames, styles, colors, and components as context for implementation work. Sketch is proprietary software with free viewing and handoff options alongside paid editing plans.
