Sketch

Sketch is a design platform that offers a native macOS app for design, prototyping, and illustration, complemented by a web app for collaboration, inspection, and asset export. It enables users to create and manage design systems through reusable components like Symbols, Text Styles, and Color Variables, which can be organized into shared Libraries for team-wide consistency and version control.

Sketch is primarily a design tool, not a dedicated brand guideline and asset management platform like ybrand. While it offers features for organizing design components (Symbols, Text Styles, Color Variables, Layer Styles) in Libraries and allows for sharing and version control, it doesn't explicitly provide a 'Brand Guideline Editor' or a 'Shareable Brand Guide URL' in the same way ybrand does. Its 'Libraries' function as a centralized asset storage and organization system, and it supports version control for these components. It also allows for collaboration and has integrations with other design and development tools. However, the core focus is on design creation and collaboration, with brand asset management being a secondary function through its component library system.
