SteamCMD is a command-line interface designed for automated, command-line interaction with the Steam client.
It is primarily used to download and update Steam games, as well as dedicated servers, through scripts or command lines. It's particularly useful for server administrators, mod developers, and anyone needing to automate the process of obtaining and managing Steam content without a graphical user interface. SteamCMD provides a streamlined and efficient method for these tasks.
It is available for Windows, Linux and MacOS.

SteamCMD requires a Steam account to download most content. Ensure you have the necessary permissions for the apps you are trying to access. Be mindful of Steam's usage policies when automating downloads to avoid potential account restrictions.

SteamCMD scripts allow you to automate sequences of commands. This is useful for tasks such as updating multiple game servers simultaneously. Scripts are simple text files containing SteamCMD commands, executed sequentially.

While anonymous login is possible for some public content, most operations require authentication with a valid Steam account. Ensure that you are using a secure method for storing and managing your Steam credentials when using SteamCMD in automated environments.

SteamCMD was developed by Valve Corporation to provide a command-line interface for managing Steam content, primarily for server administrators and developers. It became popular due to its ease of use for automating downloads and updates of Steam games and dedicated servers. It has been continuously updated to support new Steam features and improve performance.
