macOS

You can install Cecil on macOS with 🍺Homebrew:

brew install cecilapp/tap/cecil

Windows

You can install Cecil on Windows with 🍨Scoop:

scoop install https://cecil.app/scoop/cecil.json

Before 22 mai 2025, the manifest was available at https://cecil.app/cecil.json, so if you have installed it before, you need to uninstall it and install it again with the new URL:

scoop uninstall cecil
scoop install https://cecil.app/scoop/cecil.json

Or manually:

Move cecil.phar in a dedicated directory, like C:\bin
Rename it from cecil.phar to cecil
Append ;C:\bin to your PATH environment variable
Create a wrapping batch script

PHIVE

Cecil is available through PHIVE (The PHAR Installation and Verification Environment):

phive install cecil

Linux

mv cecil.phar /usr/local/bin/cecil
chmod +x /usr/local/bin/cecil

Update

The easiest way to update Cecil to the last version is to use the dedicated command:

cecil self-update

Download a specific version

If you want to download a specific version you can specify it in the URL path.
For instance, if you want to install the 8.0.0 version you need to put download/8.0.0/ in the URL:

curl -LO https://cecil.app/download/8.0.0/cecil.phar

Download the preview version

The preview version is the not yet deployed version, but ready for test.
