3 points

a year ago

Keep-Alive is a lightweight, cross-platform utility designed to prevent your system from going to sleep. It’s perfect for maintaining active connections, downloads, or any long-running process.

Features:

- Configurable keep-alive durations.

- Cross-platform support: macOS, Windows, and Linux.

- Lightweight, efficient, and easy to use.

- Uses native APIs for reliability:

  - macOS: caffeinate

  - Windows: SetThreadExecutionState

  - Linux: systemd-inhibit.

Why I Built It: I created Keep-Alive after struggling with systems going idle during tasks like large downloads or remote connections. I wanted a simple, intuitive solution that required no setup.
