What is it?

• Like asdf (or nvm or pyenv but for any language) it manages dev tools like node, python, cmake, terraform, and hundreds more.
• Like direnv it manages environment variables for different project directories.
• Like make it manages tasks used to build and test projects.

Demo

The following demo shows how to install and use mise to manage multiple versions of node on the same system. Note that calling which node gives us a real path to node, not a shim.

It also shows that you can use mise to install and many other tools such as jq, terraform, or go.

See demo transcript.

Quickstart

Install mise

See Getting started for more options.

$ curl https://mise.run | sh
$ ~/.local/bin/mise --version
2025.5.16 macos-arm64 (a1b2d3e 2025-05-29)

Hook mise into your shell (pick the right one for your shell):

# note this assumes mise is located at ~/.local/bin/mise
# which is what https://mise.run does by default
echo 'eval "$(~/.local/bin/mise activate bash)"' >> ~/.bashrc
echo 'eval "$(~/.local/bin/mise activate zsh)"' >> ~/.zshrc
echo '~/.local/bin/mise activate fish | source' >> ~/.config/fish/config.fish
echo '~/.local/bin/mise activate mise activate pwsh | Out-String | Invoke-Expression' >> ~/.config/powershell/Microsoft.PowerShell_profile.ps1

Execute commands with specific tools

$ mise exec node@22 -- node -v
mise node@22.x.x ✓ installed
v22.x.x

Install tools

$ mise use --global node@22 go@1
$ node -v
v22.x.x
$ go version
go version go1.x.x macos/arm64

See dev tools for more examples.

Manage environment variables

# mise.toml
[env]
SOME_VAR = "foo"

$ mise set SOME_VAR=bar
$ echo $SOME_VAR
bar

Note that mise can also load .env files.

Run tasks

# mise.toml
[tasks.build]
description = "build the project"
run = "echo building..."

$ mise run build
building...

See tasks for more information.

Example mise project

Here is a combined example to give you an idea of how you can use mise to manage your a project’s tools, environment, and tasks.

# mise.toml
[tools]
terraform = "1"
aws-cli = "2"

[env]
TF_WORKSPACE = "development"
AWS_REGION = "us-west-2"
AWS_PROFILE = "dev"

[tasks.plan]
description = "Run terraform plan with configured workspace"
run = """
terraform init
terraform workspace select $TF_WORKSPACE
terraform plan
"""

[tasks.validate]
description = "Validate AWS credentials and terraform config"
run = """
aws sts get-caller-identity
terraform validate
"""

[tasks.deploy]
description = "Deploy infrastructure after validation"
depends = ["validate", "plan"]
run = "terraform apply -auto-approve"

Run it with:

mise install # install tools specified in mise.toml
mise run deploy
