Alacritty
GPU-accelerated terminal emulator
Open-source Mac apps make the software running on your computer inspectable. That matters most for utilities with broad permissions—clipboard managers, transcription tools, firewalls, automation apps, and menu bar agents—because anyone can examine what data the app reads and where it sends it.
Open source does not automatically guarantee security or long-term maintenance, but it gives users and contributors a way to verify claims, report problems precisely, and keep useful software alive. The apps below span media, development, productivity, system utilities, and privacy tools built specifically for macOS.

Usually, but not always. The source code may be available while the developer charges for a signed build, automatic updates, cloud services, or support. The listing's pricing label describes the distributed app rather than the source license alone.
Check whether the repository is active, review recent releases and issues, download from the official project, and prefer signed or notarized builds. Public source makes review possible, but it is still important to verify that the binary came from the expected developer.
