TLDR

A command-line tool that automatically installs and switches between the right versions of dev tools, manages environment variables, and runs project tasks, all configured in one file.

Things people build with this

USE CASE 1

Set up a project so new team members get the exact same tool versions and environment variables by running one command.

USE CASE 2

Switch between Node.js 18 for one project and Node.js 26 for another automatically when you change directories.

USE CASE 3

Define and run common tasks like 'build', 'test', or 'deploy' from a single configuration file instead of remembering shell commands.

USE CASE 4

Ensure CI/CD pipelines use the same tool versions and settings as your local development environment.

In plain English

Mise (short for "mise-en-place," the chef's term for having everything ready before cooking) is a command-line tool that solves a common developer headache: keeping the right versions of programming tools and settings consistent across projects. When you work on multiple projects, each might need a different version of Node.js, Python, or other tools, and manually switching between them is tedious and error-prone. Mise handles three things in one tool. First, it installs and switches between dev tools, you can specify that one project needs Node version 26 and another needs Python 3, and mise automatically activates the right version when you enter each project's folder. Second, it manages environment variables (settings and secrets that programs read at startup) per project, so you never accidentally use the wrong database or API key. Third, it works as a task runner, letting you define commands like "build," "test," or "deploy" in a simple configuration file, then run them with a single command. Everything is stored in a single mise.toml file per project. New team members or CI/CD pipelines (automated build systems) just run mise install and they get the exact same setup. Mise is built in Rust, which makes it fast, and it works on any shell environment.
