I've found bin[0] to be great (and simple) to manage binaries released via github, specifically those tools not already available via macports and ones for which I'm too lazy to write a portfile for. Seems like kelp is attempting to replace this combination with one tool.
Looking at their about[0] page, it seems like Typogram is a company started by the person who also created Coding Font. That might explain the "by Typogram" label.
