# wax

wax allows running any command available in wapm, directy in your shell, without global installations that pollute your directory.

{% hint style="success" %}
wax is automatically available when you [install Wasmer](../wasmer/getting-started).
{% endhint %}

wax is a tool intended to ease the use of command-line WebAssembly applications on your system. Similarly to `wapm`, that allows the installation and usage of packages and commands, wax enables use of CLI tools without installing them globally or changing your `PATH`.

## Technical details

To improve the developer experience, wax will automatically preopen the current directory by default (passing the `--dir=.` argument to the corresponding WASI runtime).

Signed packages are automatically trusted (if seen for the first time).

Packages are installed in a temporary folder in your system, so it doesn't pollute your environment
