Sketch

Sketch provides a design application and collaboration tools used for interfaces, prototypes, and related visual projects. Its website explains the Mac-based creation experience and supported web-based review or team features.

The product, device, account, workspace, and subscription determine available tools. Web viewing and review are different from installing the main design application. Designers should check file compatibility, sharing permissions, and actual export requirements for the workflow they plan to use.

For related tasks, Sketch can be considered alongside GitHub for code repositories, issues and change reviews and MDN Web Docs for web platform documentation, html css and javascript references. These resources cover adjoining parts of the subject; each publishes its own information and handles its own service, access arrangements or applications.
