Mise

Overview

Mise is a polyglot development tool manager that handles tool versions, environment variables, and task running in a single CLI. It replaces asdf, nvm, pyenv, direnv, and Makefiles with a unified mise.toml configuration per project.

When to use: Managing multiple language runtimes per project, defining reproducible dev environments, running project tasks with dependencies, replacing scattered .nvmrc/.python-version/.tool-versions files, automating CI pipelines.

When NOT to use: Container-only workflows where all tools live in Docker images, single-language projects already well-served by their native version manager, production runtime management (mise is a dev tool).
