Sub Luna - Safari Dark Mode

Sub Luna brings instant, zero-flash dark mode to every website in Safari.

Unlike other dark mode tools, Sub Luna injects styles before the first paint — so you never see a white flash when loading pages. It just works.

FEATURES

• Zero-Flash Technology — Dark mode is applied at document_start, before the page renders. No flicker, no white flash, ever.

• 10 Beautiful Themes — Pure Dark, Dark Gray, Warm Gray, Night Blue, Sepia Dark, Violet Night, Frost Blue, Mocha, Forest, and Slate. Find the perfect look for your eyes.

• Per-Site Customization — Set different themes, brightness levels, or disable dark mode entirely for specific websites. Your rules, your control.

• Smart Detection — Automatically skips websites that already have their own dark theme (like YouTube or Twitter), so native dark modes stay untouched.

• Floating Toggle — Optional draggable button on every page for instant on/off control without leaving Safari.

• Schedule Mode — Set dark mode to activate automatically between specific hours (e.g., sunset to sunrise).

• Home Screen Widget — Toggle dark mode with one tap, right from your Home Screen.

• iCloud Sync — Your themes, settings, and per-site rules sync seamlessly across all your Apple devices.

• Privacy First — No analytics, no tracking, no ads, no account required. All data stays on your device. Period.

BUILT FOR SAFARI

Sub Luna is a native Safari Web Extension, built with Swift and optimized for iOS. It integrates deeply with Safari and iOS — not a web wrapper, not a VPN, not a proxy. Just clean, fast, private dark mode.

CUSTOMIZABLE FOR 135+ POPULAR SITES

Hand-tuned CSS fixes for Google, GitHub, Reddit, Wikipedia, Stack Overflow, and 130+ other popular websites ensure dark mode looks great everywhere — not just "good enough."
