## What it is
mise is a Rust CLI that manages dev tool versions, project environment variables, and task running from a single mise.toml file. It replaces tools like asdf, direnv, and make by preparing the full development environment before each command runs.

## Use cases
- install and pin multiple versions of node, python, and other dev tools per project
- load project-specific environment variables from .env files automatically
- define and run build, test, and lint tasks in one config file
- replace asdf for managing polyglot tool versions
- replace direnv for per-directory environment variables
- ensure CI jobs and new checkouts get identical tool setups
- automatically switch tool versions when changing directories

## When to choose
- you work across multiple languages and need per-project tool versions
- you want asdf, direnv, and a task runner combined into one fast tool
- you want a single checked-in config so every machine and CI gets the same environment

## When to avoid
- you only need a single-language version manager with deep ecosystem integration (e.g., nvm, pyenv)
- you need complex make-style dependency graphs in your task runner
- your team is not willing to adopt a shared mise.toml convention
