In plain English

Kap is a free, open-source screen recorder for Mac built with web technology (TypeScript and Electron, which lets web-based code run as a desktop app). It solves the simple but common need of capturing what is happening on your screen, whether that is a bug you want to report, a tutorial you are recording, or a quick demo to share with a colleague. Using it is straightforward: click the Kap icon in your Mac menu bar, select which part of the screen you want to capture, hit record, and click the icon again when you are done. It supports both Apple Silicon and Intel Macs and can be installed directly via Homebrew, a popular Mac package manager. The app also has a plugin system for extending its capabilities. You would use Kap any time you want a clean, no-cost screen recording tool on your Mac without the complexity of professional video software. It is aimed at everyday users who need to capture and share screen content quickly.
