Nightfall — Premium Dark Mode

About

Nightfall turns any website into a beautiful dark mode — without breaking sites that already have one.

🌙 EIGHT CURATED THEMES
Not just "dark" — pick the mood:
• Midnight — pure neutral dark
• Charcoal — soft warm gray
• Sepia Night — warm reading light, easy on the eyes for long sessions
• Tokyo Night — cool blue-purple shimmer
• Rose Pine — subtle rose tint
• Forest — earthy green-tinged shadows
• Carbon — high contrast, sharp text
• Twilight — soft purple dusk

✨ SMART AUTO-DETECT
Nightfall recognizes 1,300+ sites that already render dark by default — Discord, Twitch,  and many more. On those sites, the extension steps aside automatically. No more inverting an already-dark page into something weird.

⚙️ FOUR RENDERING MODES
• Filter — fast, broad-brush CSS filter (works on 90% of sites)
• Static — gentle CSS overrides (better for sites with canvas, maps, or games)
• Dynamic — analyzes the page's own CSS and generates a per-element dark equivalent (best visual quality on supported sites)
• Off — disable for this site

Switch modes globally or per-site. Right-click anywhere on the mode tabs in the popup to set per-site.

🎯 PER-SITE CONTROL
• Toggle dark mode on/off for any site with one click
• Save a different theme for specific sites (e.g. Sepia Night for Medium, Tokyo Night for everything else)
• Write custom CSS that applies only to one site, right from the popup
• Built-in fixes for 60+ tricky sites (Stack Overflow code blocks, Wikipedia thumbnails, Amazon search bar, etc.)

⚡ ZERO FLASH ON LOAD
Nightfall injects a baseline filter the moment a page starts loading, so you never get hit with a white flash before the dark theme kicks in.

🎨 EYE COMFORT SLIDERS
Brightness, contrast, and warmth (sepia) sliders for fine-tuning. Each theme starts with sensible defaults; tweak only what you want.

⏰ SMART SCHEDULING
• Always on
• Sunset to sunrise (auto-calculated for your time zone)
• Custom hours
• Off

🔤 FONT CUSTOMIZATION
Override page fonts site-wide with a built-in pick list (Inter, Georgia, JetBrains Mono, Atkinson Hyperlegible, OpenDyslexic, and more). Adjust text size from 80% to 140%.

⌨️ KEYBOARD SHORTCUTS
• Alt+Shift+N — open the menu
• Alt+Shift+D — toggle dark mode on the current site

🌍 LOCALIZED
English and Turkish out of the box. More languages contributable.

🔒 PRIVACY-FIRST
• Zero data collection
• Zero analytics, zero telemetry
• All your settings stay in your browser (synced via your Chrome account if you're signed in)
• Open source
• Single purpose: dark mode styling

WHY ANOTHER DARK MODE EXTENSION?

Most dark mode extensions are utilitarian — they work but the UI feels like it's from 2014. Nightfall is built with a premium feel: glass-morphism popup, smooth animations, beautiful theme cards with live previews, custom toggle switches.

Built on top of the same techniques the giants use, plus:
• Curated theme presets (most extensions only have plain "dark")
• Better detection of already-dark sites (no double-darkening)
• Cleaner per-site control workflow
• Modern, lightweight UI
