## What is it?
- Like [asdf](https://asdf-vm.com) (or [nvm](https://github.com/nvm-sh/nvm) or [pyenv](https://github.com/pyenv/pyenv) but for any language) it manages [dev tools](https://mise.jdx.dev/dev-tools/) like node, python, cmake, terraform, and [hundreds more](https://mise.jdx.dev/registry.html).
- Like [direnv](https://github.com/direnv/direnv) it manages [environment variables](https://mise.jdx.dev/environments/) for different project directories.
- Like [make](https://www.gnu.org/software/make/manual/make.html) it manages [tasks](https://mise.jdx.dev/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`.
[](https://mise.jdx.dev/demo.html)
See [demo transcript](https://mise.jdx.dev/demo.html).
## Quickstart
### Install mise
See [Getting started](https://mise.jdx.dev/getting-started.html) for more options.
```sh-session
2025.12.13 macos-arm64 (a1b2d3e 2025-12-19)
```
Hook mise into your shell (pick the right one for your shell):
```sh-session
# 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
```
### Execute commands with specific tools
```sh-session
$ mise exec node@24 -- node -v
mise node@24.x.x ✓ installed
v24.x.x
```
### Install tools
```sh-session
$ mise use --global node@24 go@1
$ node -v
v24.x.x
$ go version
go version go1.x.x macos/arm64
```
See [dev tools](https://mise.jdx.dev/dev-tools/) for more examples.
### Manage environment variables
```toml
# mise.toml
[env]
SOME_VAR = "foo"
```
```sh-session
$ mise set SOME_VAR=bar
$ echo $SOME_VAR
bar
```
Note that `mise` can also [load `.env` files](https://mise.jdx.dev/environments/#env-directives).
### Run tasks
```toml
# mise.toml
[tasks.build]
description = "build the project"
run = "echo building..."
```
```sh-session
$ mise run build
building...
```
See [tasks](https://mise.jdx.dev/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.
```toml
# 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:
```sh-session
mise install # install tools specified in mise.toml
mise run deploy
```

## GitHub Issues & Discussions
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](https://github.com/jdx/mise/discussions/categories/announcements)
- [Ideas](https://github.com/jdx/mise/discussions/categories/ideas): for feature requests, etc.
- [Troubleshooting & Bug Reports](https://github.com/jdx/mise/discussions/categories/troubleshooting-and-bug-reports)
