Somewhat similar but many differences, with my project:

- The goal is to be able to install it once and never worry again, you can simply re-run the install to update if you want

- My project doesn't have/need the ability to manage existing installs and keep track of them

- Doesn't have weird binary names or things you have to add to your `.[shell]rc`

- My project should be able to install from many sources. The main goal is to get you up and running asap

With that being said I did not know that `bin` existed. It seems more along the lines of mise or asdf
