adamchainz, 
I moved from #pyenv to #mise last week, managing both my #Python and #Node versions with it. Maybe other languages soon.
It was really smooth and it installs fast. It definitely has a better UX, especially around pulling the latest versions.
Mise: https://mise.jdx.dev/
Here’s what my Ansible-powered installation steps look like now:
