Alternate runtimes makes it easier to build Google Workspace Add-ons, now generally available

What’s changing 

We’re launching a new way to create Google Workspace Add-ons. With alternative runtimes, developers can write Add-ons in any language and on any infrastructure, and then publish them to the Google Workspace Marketplace. Alternate runtimes was previously available in beta. 

Who’s impacted 

Admins and developers 

Why it’s important 

Google Workspace Add-ons allow you to use third-party applications within Google Workspace. These integrations between Google Workspace and other productivity applications allow work to happen more seamlessly across platforms, helping you get work done faster without switching from one app to another. 

Previously, developers had to write Add-ons in Apps Script. With this launch, developers can write them in whatever language, and on whatever infrastructure, they want. This change enables developers to use the tools and systems they’re used to, making it quicker and easier to create and publish high-quality Add-ons.
