Hey Product Hunt! 👋
I built BlackScreen.page out of frustration with existing fullscreen color tools. Whenever I needed a black screen for OLED cleaning, ambient sleep lighting, or a white screen to light up a webcam call, every existing website was drowned in intrusive banner ads, slow popups, and battery-draining scripts.
BlackScreen.page is completely ad-free, open-source, and weighs under 15 kB. It also implements the native Web Screen Wake Lock API—so your monitor won't shut off after 3 minutes while you're cleaning it or using it for ambient light.
Hope you find it useful! Feedback and feature requests are very welcome.
