Sketch

What it does

Sketch is a design tool for screens, prototypes and design systems. The native Mac app is the main workspace. A web app lets teammates view, comment and collaborate in the browser, and an iPhone and iPad app previews designs and prototypes. Documents live in a shared Workspace with version history.

Why you would need it

You feel the need when design work moves from one person's laptop to a team. Files are copied, libraries drift, and developers ask which version is final. A shared Workspace with libraries, symbols and styles keeps one source for buttons, colours and type. Free viewers let clients, developers and managers look at the work without paying for a seat.

Where it fits

Sketch sits between product thinking and code. Briefs from a tracker such as Linear or Jira go in, a design comes out, and developers use the handoff view and the shared libraries to build it. It competes mainly with Figma, and with the open-source Penpot. Sketch is Mac-first, so check how your team's non-Mac users will work with it.

Who it suits

Standard is aimed at individuals and small teams, Professional at growing teams and agencies, and Enterprise at medium and large organisations. Because viewers are free, three designers can share work with twenty reviewers without adding paid seats. Developers get handoff without a seat too, which is where design tool costs usually grow.

What stands out

• A native Mac app with real-time collaboration through Workspaces.
• Unlimited free viewers and free developer handoff on subscriptions.
• A developer toolkit: a JavaScript API, plugins, a command line tool called sketchtool, and a documented JSON file format.
• An official MCP server that lets an AI client read and change the open document.
• A one-time Mac-only licence for people who work alone and offline.

My take

I would pick Sketch when the team already works on Macs, values a fast native app and wants a calm tool for interface and design system work. The extension model is a real advantage if you want to script your design workflow.

I would not pick it when your team is mixed across operating systems and most work happens in the browser. A browser-first tool is simpler there.

Verdict

Pick it when your designers are on Macs and you want native speed, shared libraries and free viewers. Skip it when everybody needs full editing in the browser, or when the rest of your company already works in another design tool.
