About this extension
Turn GitHub into a true Pitch Black theme — with zero slowdown.
Most themes work by running extra code in your browser every time a page loads, which can slow things down or cause a flash of the wrong colors first. This one works differently: it's pure styling, with no code running at all, so the black theme is just there — instantly, every time.
FEATURES:
🌑 True Pitch Black — swaps GitHub's dark gray background for pure black.
⚡ Instant — no delay, no flicker, no lag.
🎨 Clean, Neutral Look — softer grays instead of harsh blue tints.
🔋 Battery Friendly — pure black uses less power on OLED phone and laptop screens.
Note: your GitHub account also needs to be set to Dark mode — this extension recolors the dark theme, it doesn't turn dark mode on for you.
PRIVACY, GUARANTEED:
🔒 No code runs in your browser at all — just colors. There's nothing that could track you, collect your data, or send anything anywhere, even by accident.
🔒 No analytics, no trackers, no background activity of any kind.
🔒 100% open source — anyone can read every line of it, nothing hidden.
UNDER THE HOOD:
No JavaScript, no background service worker — just a static CSS file declared in
