Night Owl

A cross-browser dark-mode extension that makes bright sites easier on the eyes without distorting media or brand colours.

Project visual coming soon

A project image, interface screenshot, or architecture visual can be added here later without changing this page layout.

Overview

Night Owl detects bright document canvases, prefers a site’s own clear dark-mode control where possible, and otherwise applies a layered dark palette. It protects photos, video, gradients, and vivid branded areas while keeping preferences private and local.

What it does

  • Darkens only pages that need it in Auto mode
  • Preserves media, background imagery, gradients, and brand-colour blocks
  • Lets users permanently exclude individual sites
  • Builds separately for Firefox and Chromium from the same source
