Chromeless Frames

Chromeless Frames is a Figma library of browser windows for presenting web work: 30 variants covering light and dark themes, three operating-system styles, a minimal frame with only traffic lights, and tablet and phone browser chrome. Tabs, address bars and toolbars use auto-layout, so you can type a URL and add tabs without breaking anything.

It's a staple for case studies, documentation screenshots and marketing pages that show a web app. It's released under the MIT license with the source file public. The caveat: the frames are vector and flat, so for perspective or photographic scenes you'll still need a separate mockup pack.
