Figma

Figma is an online tool for designing user interfaces and collaborating as a team. It grew into the designer's standard for building screens for websites, mobile apps and digital products, and today it's used by everyone from solo freelancers and startups to large product teams. It suits anyone who needs to visually design how their app or website should look and share it with others.

You work directly in the browser — nothing to install, and the file always lives in the cloud. You create a canvas, draw screens from shapes, text and images, and connect them into a clickable prototype that shows how the app will behave. Multiple people can edit the same file at once, see each other's cursors and changes, and add comments right on the design.
