You Decide: Dark or Light Dark Light is a lightweight browser extension where you decide how each website looks. Control your web! Dark Light isn't just another dark mode. It elegantly forces any website into dark or light mode. Set global defaults or customize rules per site. Unlike typical dark-mode extensions, Dark Light also gives you a reliable light mode. Darken bright sites, or turn dark sites back to light when you need it. Control Appearance Per Domain Set a global default, then give any website its own rule. Four Modes Follow System, Preserve Site Design, Force Dark, and Force Light are available as global defaults and per-site overrides. Domain Rules Give each website its own appearance mode, including optional subdomain matching. Not Just Dark Mode Most extensions stop at dark mode. Dark Light also includes Force Light, so dark websites can be switched back to light.
