Google Apps Script is a free, cloud-based JavaScript platform enabling users to automate tasks and extend functionalities across Google Workspace apps. Ideal for marketers, designers, and developers, it empowers custom integrations for Sheets, Docs, and Gmail. It excels in ease of use and cost-effectiveness but may lack advanced features compared to alternatives like FlutterFlow or Code Blocks. Support can be limited, but its seamless integration into Google Workspace ensures high efficiency at no additional cost.
