Judgement

What it is

Developer tool

What it does

One CLI that installs per-project versions of language runtimes and tools, loads environment variables as you enter a directory, and runs tasks defined in a mise.toml file.

Adopt it when

Your team juggles nvm, pyenv, asdf, direnv and make-style scripts and wants one config file that works the same in the shell, the editor and CI.

Watch out

It changes fast with calendar-versioned releases and leans heavily on its lead maintainer, so pin a version in CI.
