Mise

Mise is a polyglot tool version manager and task runner. It manages dev tools, environment variables, and tasks for projects.

Core Concepts

Configuration: mise.toml in project root (or .mise.toml, .config/mise/config.toml). Config is hierarchical - child directories override parent settings.

Tools: Defined in [tools] section. Mise installs and activates correct versions per-directory.

Environment: Defined in [env] section. Set project-specific env vars that activate when entering directory.

Tasks: Defined in [tasks] section or as standalone scripts in mise-tasks/ directory.
