Wideawake: Auto-detect agents and prevent your Mac from sleeping (github.com)

WideAwake is a new macOS menu bar application designed to enhance productivity for developers by preventing their Mac from sleeping while AI coding agents like Claude Code and Codex are in use. By monitoring these agents, it ensures that long-running tasks remain uninterrupted, automatically re-enabling sleep when work is complete. This functionality is especially crucial for developers who rely on AI for coding assistance, as interruptions can lead to loss of progress and unintentional errors. The app also offers additional features, such as preventing lid-close sleep, which allows users to close their laptops without stopping ongoing processes. It includes hourly check-ins to confirm that users wish to keep their machines awake, and starts automatically upon login, facilitating seamless usage right from the outset. WideAwake requires macOS 13 or higher and the Xcode Command Line Tools, enabling easy installation through a straightforward command line process. This utility addresses a common challenge in development workflows, enhancing the efficiency and reliability of AI-assisted coding tasks.
