Order is by GitHub stars among apps that install as a ready-made Mac app. Descriptions are the developers' own; versions and star counts are refreshed with the catalog.

Command-line tools are usually installed with Homebrew rather than as an app. OpenDMG covers the apps: the things with a window, a menu bar icon or a place in your Applications folder.
