It looks cool but I feel this kind of tool is only useful if Ruby is the only language you use. I have to manage several runtimes for most projects. I've used asdf for years and recently switched to mise: these tools already download pre compiled binaries for Ruby, plus pretty much any other language runtime.

It's likely that you get better per language features for something specific to the language though. We end up in exactly the same kind of frustration, that for some random project you need this specific tool that does dependency management of the specific runtime. asdf and mise both respect a .tool-versions file, I'd rather see things go more in that direction with some kind of standard.

Wait, how do you get precompiled Rubies with mise? I still have to compile with default settings, and the docs only mention that it uses ruby-build behind the scenes: https://mise.jdx.dev/lang/ruby.html

I don't think you can. I also don't know why people care so much about it - I work full time with ruby and compiling a new version, which maybe takes 10 minutes, a couple times a year is no big deal.

I think it comes mostly from CI environments that start entirely clean before every run. 10 minutes every time a commit is pushed is not pleasant. That's not how I'd like CI to work, but sadly it seems to be the current state of things.

I've only used circleci and github actions for this, but in both cases precompiled rubies are available. On circleci you run your tests on a ruby docker image with the right version of ruby installed. On Github Actions I use https://github.com/ruby/setup-ruby, which installs an compiled ruby in a second or two, and also properly caches your gems. I think if someone's CI environment is building ruby from source they are doing it wrong.
