Noctis — Dark Mode
View on Chrome Web StoreChrome will indicate if you already have this installed.
Overview
Noctis turns the bright web dark - on any site, instantly.
Most pages are still built light-first. Noctis rewrites them into a comfortable
dark theme so late-night reading, low-light rooms, and long screen sessions stop
straining your eyes. One click (or Alt+Shift+D) toggles it everywhere.
━━ THREE WAYS TO GO DARK ━━
• Dynamic (default) - The smart engine reads each site's own stylesheets and
recolors backgrounds, text, borders, and icons toward a dark palette using
real luminance + HSL math. It never edits the site's CSS, so layouts stay
intact. Handles cross-origin styles, @media/@supports blocks, content that
loads after the page, and even Shadow DOM / web components.
• Simple - A fast, clean blanket dark theme from your chosen palette. Great when
you want speed over per-element fidelity.
• Filter - A universal invert + hue-rotate that works on absolutely anything,
with photos and videos re-inverted so they still look right.
━━ BUILT TO FEEL RIGHT ━━
• No white flash - pages are darkened before they paint, so you never get
blinded on load.
• Already-dark detection - sites that already ship their own dark theme are left
alone automatically.
• Tells you why - if a page is skipped, Noctis shows a small note explaining why
(already dark, or on your site list) with a one-click "Darken anyway."
• Per-site control - keep dark mode off on chosen sites (exclude list) or run it
ONLY on sites you pick (include list). Toggle from the toolbar or right-click.
• Scheduling - go dark and light automatically at the times you set.
• Color temperature - an optional warm overlay cuts blue light for night use.
• Your palette - customize background, text, link, visited, and border colors.
━━ FAST & PRIVATE ━━
• No accounts, no sign-in, no tracking, no ads.
• Noctis does not collect, store, or transmit any personal data. Your settings
live only in your browser.
• Works offline.
━━ HOW TO USE ━━
1. Click the moon icon to open the popup — toggle dark mode, switch styles, or
turn it off for just the current site. (Alt+Shift+D toggles instantly.)
2. Open "All settings" for the full controls: mode, custom colors, per-site
lists, schedule, and night-light warmth.
Note: browsers don't allow extensions to run on internal pages like chrome:// or
the Chrome Web Store. On those pages the popup simply tells you it can't run
there.
Love it or hit a site that doesn't look right? Use the right-click menu to
exclude it, or switch that tab to Filter mode for guaranteed coverage.
