Dim: Dark Mode for the Web
Night mode browser extension
Only for Mac
Free
Mac
Every website dark, instantly. One price, everything included — no subscription, no account, and not a single network request. Your browsing never leaves your Mac.
Dim is a browser extension for Mac that works with Safari. It makes every website dark — including the ones that never bothered to offer a dark theme.
ONE PRICE. THAT'S THE WHOLE PRODUCT.
You pay once. Everything is unlocked. There is no subscription, no free trial that quietly expires, no account to create, and nothing held back for a "pro" version. What you install is what you bought.
IT DOESN'T SLOW YOUR BROWSER.
Dim applies a single stylesheet, once, when a page loads. It doesn't watch the page or recalculate anything as you scroll or type. Measured on real sites in the browser's own engine: 8 milliseconds per page.
IT NEVER SENDS ANYTHING ANYWHERE.
Dim makes zero network requests. Not for analytics, not for updates, not for anything. There is no server on the other side because there is no other side. Open the Web Inspector and watch the Network tab stay empty.
IT RESPECTS SITES THAT ALREADY GOT IT RIGHT.
When a site already has a dark theme of its own, Dim uses that instead of overriding it. A theme designed by the people who built the site will always look better than one applied from the outside.
WHEN YOU WANT IT
• Always on
• Follow your Mac — switches automatically with light and dark appearance
• On a schedule — from sunset to morning, or any hours you choose
CONTROLS
• On or off per website, remembered
• Contrast and brightness
• Dim bright images so they don't glare on a dark page
• Settings sync across your Macs
HONEST ABOUT THE LIMITS
Dim inverts colors on sites that have no dark theme. That's a fast, predictable approach, and on a small number of pages it can look off. When that happens, switch Dim off for that site with one click and it stays off.
