Arch does much better, but a quick search of ones I guessed might be missing turned up the following missing, from what I have installed on my Mac:

- rolldice

- android studio (package name android-studio in homebrew)

- tealdeer

- heroku (these are the Heroku command line tools)

- sublime text (package name: sublime)

- postman

- slack

Maybe you can add other repos to get them on there, but I usually just guess the package name and get what I want. I don't think I have a single thing on my Mac, as far as software I directly use (not project dependencies), that I didn't install with Homebrew, aside from first-party Apple software (Pages, Numbers, Safari, Xcode, Mail, and so on). And that's not bringing up all the Mac-only software I've installed with it, which obviously wouldn't be fair.

I haven't added a single extra repo. That's just with the defaults. You used to have to do a one-time invocation to enable binary-only packages (mostly closed-source stuff) and then use a different keyword for operating with them, but that's no longer the case and hasn't been for IIRC at least a year—it's all transparent. "brew install [guess at package name]" works almost every time I need it, and a "brew search" finds the rare failures. I basically never need to open a browser to find & download software, and it's all up-to-date, and it's all totally separate from my base system so is extremely unlikely to ruin my morning because I ran a blanket update-everything-to-latest and didn't pay enough attention.
