Every screen tool you need.
No download.
Colors, monitor tests, timers, fake updates, prank screens, and screensavers. Open the tab, press F, get to work.
One key to fullscreen
Press F or use the controls. ESC always brings the browser chrome back.
Keyboard-first controls
Switch colors, start timers, jump tools without leaving the keyboard.
Nothing leaves your tab
Everything runs locally. No accounts. No telemetry. Tools work offline once loaded.
Seven hubs. Ninety-six tools. Pick the one for your screen.
Each tool runs in its own route, opens fullscreen, and remembers nothing except your last brightness setting. Built to be linked, not bookmarked.

Use the keyboard
Every tool ships keyboard shortcuts. Space to pause, arrow keys to switch, R to reset.
Questions, before you press F.
The same eight questions land in our inbox every week. Here they are, answered.
Will any of this hurt my screen?
No. These tools draw pixels like any other web page. The OLED burn-in fixer and pixel-stuck cycler are designed to recover, not damage.
Are these really 100% free?
Yes. No accounts, no paywalls. Hosting and bandwidth are covered by tiny contextual ads at the bottom of articles, never inside the tools themselves.
Does fullscreen work on iOS Safari?
Mobile Safari does not expose true fullscreen, but you can hide the address bar by adding the page to your home screen. Every tool is built mobile-aware.
Can I use the green-screen page for OBS chroma key?
That is the point. The page renders a flat ITU-R BT.709 chroma green at 100% brightness. Brighten the surrounding room evenly and it keys cleanly.
Why a dark UI for a site about colors?
A dark chrome lets each tool's actual color reach the eye without surrounding bias. The chrome is the picture frame, not the picture.
Is there a mobile app?
Not yet. The whole point is that none of this needs an app. Add the homepage to your home screen and it launches like one.
The tab that does the boring thing perfectly.
Open a color. Run a test. Set a Pomodoro. Or just bounce the DVD logo and wait for the corner hit.
