Sketch

The original modern UI design tool — a native macOS app that pioneered the design system era. 2026 updates include a local MCP server (connect Claude or Codex directly to your documents), a new eyedropper with colour variable support, selection colours, independent borders, and a revamped fonts panel with In Use / All Fonts tabs. Loyal community, faces headwinds from Figma, but keeps investing in craft and AI integration on its own terms.
