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.
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.
See Getting started for more options.
$ curl https://mise.run | sh
$ ~/.local/bin/mise --version

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 pwsh | Out-String | Invoke-Expression' >> ~/.config/powershell/Microsoft.PowerShell_profile.ps1
$ mise exec node@26 -- node -v
mise node@26.x.x ✓ installed
v26.x.x
$ mise use --global node@26 go@1
$ node -v
v26.x.x
$ go version
go version go1.x.x macos/arm64
See dev tools for more examples.

mise.toml

[env]
SOME_VAR = "foo"
$ mise set SOME_VAR=bar
$ echo $SOME_VAR
bar
Note that mise
can also load .env
files.

mise.toml

[tasks.build]
description = "build the project"
run = "echo building..."
$ mise run build
building...
See tasks for more information.
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
Find more examples in the mise cookbook.
See mise.jdx.dev
Due to the volume of issue submissions mise received, using GitHub Issues became unsustainable for the project. Instead, mise uses GitHub Discussions which provide a more community-centric platform for communication and require less management on the part of the maintainers.
Please note the following discussion categories, which match how issues are often used:

• Announcements
• Ideas: for feature requests, etc.
• Troubleshooting & Bug Reports
