Download and install

Scarb is a native command line application that is available for Linux, macOS and Windows on all common CPU architectures.

Scarb follows a biweekly release schedule. Each release may include new features, enhancements, bug fixes, deprecations and breaking changes. For detailed information about each release, consult the release notes.

If you are not sure if you have Scarb installed or not, you can run scarb --version in your terminal.


To download Git dependencies, Scarb requires a Git executable to be available in the PATH environment variable.

Install via installation script

Installing via installation script is the fastest way to get Scarb up and running. This method only works on macOS and Linux.

Run the following in your terminal, then follow the onscreen instructions. This will install the latest stable release.

curl --proto '=https' --tlsv1.2 -sSf | sh

Run following command if you want to install the latest nightly release.

curl --proto '=https' --tlsv1.2 -sSf | sh -s -- -v nightly

If you want to install a specific version of Scarb (such as a preview or nightly version), run the following with the desired version number.

curl --proto '=https' --tlsv1.2 -sSf | sh -s -- -v 2.6.5


The installation script does not have uninstalling logic built-in. It tries to minimize changes performed to the system, though, to keep the number of manual steps to remove Scarb low.

  1. Remove the $XDG_DATA_HOME/scarb-install directory, usually this is ~/.local/share/scarb-install.
  2. Remove ~/.local/bin/scarb symbolic link.

The installation script might have added path to ~/.local/bin to $PATH, by adding appropriate lines to .bashrc, .zshrc or others, depending on the shell running in the system. If you wish, you can remove these lines, but often this is not desirable.

On top of that, Scarb creates several files (like data files or caches) in standard system paths. These have to be removed manually. The list of all global paths written to by Scarb is listed in here.

Install via asdf

asdf is a CLI tool that can manage multiple language runtime versions on a per-project basis. Scarb team maintains an official plugin for asdf which manages multiple Scarb installations. Mind that asdf works on macOS and Linux only. This plugin needs bash, curl, tar and other generic POSIX utilities. Everything should be included by default on your system.

First install asdf by following the official installation guide. Make sure to complete all installation instructions from the guide, in particular add asdf to your local shell's configuration. Then run the following command to add the scarb plugin:

asdf plugin add scarb

Show all installable versions:

asdf list-all scarb

Install latest version:

asdf install scarb latest

Install specific version:

asdf install scarb 2.6.5

Set a version globally (in your ~/.tool-versions file):

asdf global scarb latest

Check asdf guide for more instructions on how to install & manage versions.

By operating system

Choose your operating system and tool.


As for now, Scarb on Windows needs manual installation, but necessary steps are kept to minimum:

  1. Download the release archive matching your CPU architecture.
  2. Extract it to a location where you would like to have Scarb installed. A folder named scarb in your %LOCALAPPDATA%\Programs directory will suffice:
  3. Add path to the scarb\bin directory to your PATH environment variable.
  4. Verify installation by running the following command in new terminal session, it should print Scarb and Cairo language versions:
    scarb --version


Simply undo steps done to manually install Scarb:

  1. Remove extracted archive files.
  2. Remove the path to the scarb\bin directory from PATH.

On top of that, Scarb creates several files (like data files or caches) in standard system paths. These have to be removed manually. The list of all global paths written to by Scarb is listed in here.


The community-maintained Cairo Nix overlay provides a ready-to-use Cairo development environment, which includes Scarb.

Consult release notes for exact commit hashes and more information. Each build is identified by calendar day it was produced, and are tagged in the following pattern: nightly-YYYY-MM-DD, for example: nightly-2023-08-03.

These builds are created automatically, unattended. Use at your own risk.
