AwakeMode is a lightweight browser utility that prevents your computer from sleeping or locking during long downloads, live presentations, dashboard monitoring, screen sharing, or deep work sessions. You can start an indefinite wake session or set a timer, all without installing anything or creating an account. The tool runs entirely in-browser and is designed with clean, stable UI selectors and machine-readable metadata, making it unusually well-suited for browser automation, AI agents, and QA testing workflows that need predictable app state.
