Sketch

One platform with everything you need Sketch is a platform for the entire collaborative design process. With features like prototyping and developer handoff all built in, you won’t need to pay for additional apps or plugins.

With Sketch, you get:

• Best-in-class Mac app to create designs and build prototypes. With real-time collaboration, a full offline mode, an intuitive interface, and all the power of truly native macOS software.
• Set of web-based collaboration tools that help you share ideas, test prototypes, gather feedback and hand off designs to developers — in any web browser.
• Shared Workspace to store and organize all of your designs. With a version history for every document, and powerful permissions that make it easy to share work with the right people, at the right time

Features:

• Real-time collaboration: When it’s time to get on the same page, multiple designers can jump into the same document and work together, in real-time, right inside the Mac app.
• Components Management: Build scalable design systems with Symbols and Shared Styles, then manage them effortlessly from the Components View (on the Mac and in the browser).
• Shared Libraries: Every designer in your Workspace gets instant access to Shared Libraries of components, making it easy to set up, share and update your design systems.
• Workspaces: Shared Workspaces bring everyone together and put all of your work in one place. No email attachments or save conflicts, just a full version history and a single source of truth for every file.
