ScreenTools
90+ free browser tools for every screen. Zero install.
Millions search "white screen for video call" or "dead pixel test" and end up downloading sketchy apps. ScreenTools fixes that — 96 browser-native tools in one bookmark. Use your display as a video-call key light, monitor diagnostic, classroom timer, fake Windows update prank, DVD screensaver, or OLED sleep soundscape. Everything renders live in your tab. No install, no account, no ads. Open, press F, done. Built because I got tired of single-purpose apps for things a browser tab does better.
Hey Product Hunt! 👋
I'm the maker of ScreenTools. The idea came from a simple frustration: why do I need to download an app just to show a white screen for a video call, or test my monitor for dead pixels? A browser tab can do all of this — and better.
So I built 96 tools across 7 categories: colors & lighting, monitor diagnostics, timers, prank screens, screensavers, and ambient soundscapes. Every single one runs entirely in your browser — no install, no account, no tracking.
What's free: Everything. All 96 tools, no paywall, no premium tier.
I'd love your feedback:
Which tool do you find most useful?
What screen utility am I missing?
I'll be hanging out in the comments all day — ask me anything!
