At Config 2025, Figma launched several new features, one of those being Figma Sites. The idea behind this feature is to be able to design, build, and publish everything within Figma. Here are some of the main features they shared for Figma Sites.
Responsive Design
Pages are built responsively for desktop, tablet, and mobile with the option to add custom breakpoints as needed. This allows for more customization and fine tuning at each screen size. There is also a multi-edit tool that allows changes to cascade from desktop to mobile, so edits only need to be made in one place. In the demo, they also showed that you can copy over a design from another file, and then generate screens for tablet and mobile.
