RV (something like Python's UV, but for #Ruby) looks pretty cool https://andre.arko.net/2025/08/25/rv-a-new-kind-of-ruby-management-tool/

I liked using UV with Python and I'm guessing the experience with RV would be similar as well. It's a bit said that all such tools have to be rewritten in #Rust (or similar), but nothing's perfect. On the bright side - perhaps that would encourage me to do something meaningful with Rust… (RuboCop in Rust anyone? :D)
