The web at night.
Done right.
Cinematic dark mode for every website — with per-site control,
real-time tuning, and deep optimization for Google Docs and Sheets.
ON
Everything you need.
Nothing you don't.
Built for Safari. Designed to disappear into your workflow.
Your rules, per site.
Dark mode where you want it, off where you don't. Nightfall remembers every site individually. One toggle — no global settings to fight with.
Tuned to your eyes.
Adjust brightness, contrast, and color temperature in real time — no reload, no delay. Fine-tune once per site, and Nightfall holds those settings across every visit.
Inversion that looks good.
Nightfall applies CSS filter inversion with hue correction, then counter-inverts images and video so they stay true. The dark web, the way it should look.
Follow the system. Or don't.
Enable "Match System Dark Mode" and Nightfall only activates when macOS switches to dark appearance. Or take full manual control — it's up to you.
⌘⇧E. Done.
Toggle dark mode for the current site without touching the mouse. Fully customizable from the settings page. Works even when the popup is closed.
Zero bloat.
No frameworks. No trackers. No external servers. Pure JavaScript and CSS, requesting only storage and activeTab permissions. It stays out of your way.
Where it matters most.
Some sites need more than a filter. Nightfall goes deeper.
Google Docs renders pages onto canvas tiles — a naive inversion breaks the whole thing. Nightfall's dedicated engine handles each canvas layer individually, counter-inverts embedded images with surgical precision, and preserves cursor colors. Your documents look exactly right, just darker.
Frozen rows, column headers, charts, embedded images — Sheets is complex. Nightfall's Sheets engine handles each element correctly so your spreadsheets are legible, comfortable, and visually consistent in the dark.
Built and improved,
one version at a time.
The web looks better in the dark.
$1, one time. No subscription. No data collected. Just dark mode that works.
