To install the wmill CLI, follow these steps:

  1. Make sure you have Deno installed. If not, you can install it by following the instructions here.

Please note that your version of Deno should be recent (greater than 1.32). If not, you can update Deno by running deno upgrade.

  1. Install wmill CLI using the following command in your terminal:
deno install -q -A

Your terminal might also ask you to update your PATH environment variable to include the newly installed executable wmill. Example:


export PATH="$HOME/.deno/bin:$PATH"


export PATH="/Users/<username>/.deno/bin:$PATH"

In an enterprise setting with custom certificates, you can set the following env variable to use system certificate store:

export DENO_TLS_CA_STORE=system

Alternatively, you can edit the wmill binary to ignore CA issues:

sed -i 's/deno run/deno run --unsafely-ignore-certificate-errors/' ~/.deno/bin/wmill

Also, to punch through some networking layers like Cloudflare Tunnel, you might need some custom headers. You just need to use the HEADERS env variable:

export HEADERS=header_key:header_value,header_key2:header_value2
  1. Verify that the installation was successful by running the following command:
wmill --version

If the installation was successful, you should see the version of wmill that you just installed.

Upgrade wmill

To upgrade your wmill installation to the latest version, run the following command:

wmill upgrade
