Night Shift Pro
Extension Actions
Auto dark theme for every website with one toggle, freemium controls, custom themes, and hybrid schedule mode.
Night Shift Pro brings automatic dark mode to every website with a single toggle. No more blinding white pages at midnight, no more squinting at bright dashboard — just readable, comfortable dark themes everywhere.
WHAT IT DOES
One toggle flips every website you visit into a dark theme, instantly. Your existing site preferences and layouts stay intact; only the colors change. Pages that already ship a dark theme are detected automatically so Night Shift stays out of the way.
KEY FEATURES
• One-click global dark mode for every site
• 4 premium themes: Default, Warm, Blue, and AMOLED (true black for OLED screens)
• Brightness, contrast, sepia, and font color sliders for personal tuning
• Per-site rules: always-on, never-on, or custom appearance per domain
• Hybrid schedule: manual start/end times or automatic sunrise/sunset (computed locally from your device location — no server calls)
• Site management dashboard to review, search, and organize every configured domain
• Anti-flash preload shield so dark pages load dark, not white-then-dark
• Built on Manifest V3 for modern Chrome
HOW IT WORKS
Under the hood, Night Shift uses a modern dark-mode engine to recolor CSS in real time. For sites that already implement a native dark theme (like GitHub, Twitter/X, YouTube), it detects the existing dark surface and stays out of the way instead of double-darkening.
