Keep Screen On

Display sleep interruption affects workers across industries, from someone presenting to a boardroom to developers monitoring overnight builds. Keeping a display awake without installing software has historically required either system tweaks, third-party applications, or sacrificing device settings entirely.

Keep Screen On solves this friction point by delivering wake-lock functionality directly through a browser. The product leverages the W3C Screen Wake Lock API—a web standard most modern browsers support—to prevent display sleep without requiring downloads, extensions, or administrator privileges.

The core experience is deliberately minimal. Users select a duration from preset intervals (15 minutes, 30 minutes, one hour, two hours) or set a custom timer, then activate a single button. A visual indicator confirms the wake lock is active. The browser tab remains open in the foreground or background while the display stays illuminated until the timer expires or the user manually disables it.

What distinguishes this product is its commitment to simplicity and privacy. The entire tool operates locally on the user's device with zero data collection, no tracking cookies, and no analytics. There are no telemetry concerns or privacy trade-offs to weigh. The lightweight implementation means negligible CPU and memory overhead, a consideration for users on battery power or older hardware.

Compatibility spans major operating systems and browsers: Windows, macOS, Linux, iOS, iPadOS, Android, and devices running Chrome, Safari, Microsoft Edge, and Brave. Platform-specific documentation addresses quirks—such as iOS requiring foreground tab visibility and Android supporting Chrome or Samsung Internet—that reflect real differences in how each system handles wake locks.

The product targets professionals working from home on managed IT infrastructure who need screen-awake functionality without circumventing security policies. It also serves anyone performing extended tasks—file downloads, render jobs, presentations—who would otherwise lose productivity to display timeouts.

Keep Screen On is completely free with no premium tiers or hidden revenue model mentioned. The business model remains unstated, which is unusual for a startup directory submission, though the product's simplicity and browser-based delivery suggest minimal operational costs.
