KeepingYouAwake is a small menu bar utility for macOS (Version 10.12 and newer) that can prevent your Mac from entering sleep mode for a predefined duration or as long as it is activated. The app is a small wrapper around Apple's caffeinate command line utility. All current versions of macOS ship with this tool by default. On a MacBook this only works as long as the lid is open. This utility will not harm your Mac because it is based on an official command line tool by Apple. Version 1.5.2 is the latest release that supports macOS Yosemite and El Capitan. KeepingYouAwake uses Sparkle's ui-separation-and-xpc branch to deliver updates. You can build and sign Sparkle with make Vendor. To build a release version of the app just run make dist.
