Add-ons are customized applications that integrate with Google Workspace applications.

Build in any runtime

You can develop add-ons with your preferred hosting infrastructure, development tool chain, source control system, coding language, and code libraries.

Google Workspace Add-ons built in any runtime need to return properly formatted JSON for the interface to render as cards. Then you can use the Google Workspace Add-ons API to create and manage your add-on deployments.

Build in Apps Script

This documentation explains how to build and deploy a Google Workspace Add-on in any runtime. To build and deploy add-ons in Apps Script, see the Apps Script documentation.
