ScreenTools
90+ free browser tools for every screen. Zero install.
What it does
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.

- H6Homebrew 6.0.0▲1,481
Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
