What is mise?

mise (pronounced "meez", short for mise-en-place) manages a project's dev tools, environment variables, and tasks from one mise.toml that works across your shell, editor, and CI:

[tools]
node = "24"
python = "3.14"
rust = "stable"
"cargo:cargo-nextest" = "0.9"
"github:BurntSushi/ripgrep" = "15"
"npm:prettier" = "3"

[env]
NODE_ENV = "development"
_.file = ".env"
_.path = "./node_modules/.bin"

[tasks.build]
description = "Build the application"
run = "npm run build"

[tasks.test]
description = "Run the test suite"
depends = ["build"]
run = "pytest && npm test"

• Install dev tools such as Node.js, Python, Go, Rust, and Terraform from a registry of 1,000+ tools or directly from backends like GitHub releases, Aqua, Cargo, npm, and PyPI, with separate versions per project.
• Load environment variables, .env files, PATH entries, virtualenvs, and secrets automatically as you enter a directory.
• Run tasks defined in mise.toml or as scripts in mise-tasks/, with dependencies, parallel execution, file watching, and the project's tools and environment already configured.
• Set up a machine with mise bootstrap and mise dot apply to apply system packages, dotfiles, Git repositories, macOS defaults, and background services.

Adopt only the parts you need. Start with a single tool or task, and keep any existing .tool-versions files as they are; mise also reads .nvmrc, .python-version, and other idiomatic version files once enabled.

See the demo transcript for the commands shown above.

Quickstart

1. Install mise

On macOS or Linux:

curl -fsSL https://mise.run | sh
~/.local/bin/mise --version

On Windows, run winget install jdx.mise. For Homebrew, apt, dnf, Scoop, and other package managers, see Installing mise.

The installer places the binary at ~/.local/bin/mise. If ~/.local/bin is not on your PATH yet, run ~/.local/bin/mise in place of mise until you activate mise in step 4.

2. Run a tool without changing your shell

mise exec node@24 -- node --version
# v24.x.x

mise exec downloads Node.js 24 if needed and runs the command after -- with that version on PATH. Your shell and config files stay untouched.

3. Configure a project

Create a project directory, select Node.js 24, set an environment variable, and add a task:

mkdir my-project && cd my-project
mise use node@24
mise set NODE_ENV=development
mise tasks add hello -- node -e "console.log(process.version, process.env.NODE_ENV)"

These commands install Node.js 24 and write mise.toml:

[tools]
node = "24"

[env]
NODE_ENV = "development"

[tasks.hello]
run = 'node -e "console.log(process.version, process.env.NODE_ENV)"'

Run the task with mise run:

mise run hello
# [hello] $ node -e "console.log(process.version, process.env.NODE_ENV)"
# v24.x.x development

Commit mise.toml so teammates and CI get the same setup when they run mise install or mise run. "24" requests the latest release in the Node.js 24 series; run mise lock to record exact versions and checksums in a lockfile, or mise use --global node@24 to set a personal default in ~/.config/mise/config.toml.

4. Activate mise in your shell (optional)

Shell activation updates PATH and project environment variables whenever you change directories, so you can invoke node directly without mise exec. If you installed with mise.run, run the command for your shell once, then open a new terminal:

# bash
echo 'eval "$(~/.local/bin/mise activate bash)"' >> ~/.bashrc

# zsh
echo 'eval "$(~/.local/bin/mise activate zsh)"' >> "${ZDOTDIR:-$HOME}/.zshrc"

# fish
mkdir -p ~/.config/fish
echo '~/.local/bin/mise activate fish | source' >> ~/.config/fish/config.fish

If a package manager installed mise, use mise in place of ~/.local/bin/mise. With Homebrew, fish activates mise without this step.

For PowerShell, Nushell, Elvish, Xonsh, and IDE or CI shims, see Shell setup and Shims.

Everyday commands

Command	Action
mise use node@24	Install a tool and record it in the current project's mise.toml
mise use --global node@24	Install a tool and set it as your global default
mise install	Install all tools declared in the active config files
mise exec -- <command>	Run a command with the project's tools and environment
mise run <task>	Run a project task with its dependencies, tools, and environment
mise set KEY=value	Set an environment variable in mise.toml
mise env	Print the resolved environment variables and PATH changes
mise ls --current	List the tool versions active in the current directory
mise outdated	List tools with newer releases than the installed version
mise upgrade	Install those newer releases
mise lock	Write exact tool versions and checksums to mise.lock
mise config ls	Show the config files loaded for the current directory
mise doctor	Check your mise installation, shell activation, and configuration

Set up a machine with mise bootstrap

Beyond project directories, ~/.config/mise/config.toml can declare the state of your machine:

[bootstrap.packages]
"apt:build-essential" = "latest"
"brew:jq" = "latest"

[bootstrap.repos]
"~/src/app" = { url = "https://github.com/you/app.git" }

[dotfiles]
"~/.zshrc" = { mode = "track" }

Preview and apply the configuration, or bootstrap a new machine directly from a Git repository:

mise bootstrap --dry-run
mise bootstrap
mise bootstrap --adopt you/dotfiles

See Bootstrap and Dotfiles for supported package managers, dotfile tracking and templating, services, and remote SSH targets.
