App Framework

This document helps you understand what the Hygraph App Framework is and what you can do with it. With the App Framework, you can extend the core capabilities that Hygraph offers. It gives you the possibility to create your own custom apps, and (optionally) share them with other users.

The App Framework is a toolset that allows you to build apps easily. You can use it to build apps that integrate Hygraph with third-party services, or build custom integrations tailored to your specific needs.

#What are apps?

Apps are packages that extend Hygraph in various ways. Apps allow for simpler customization and integration of your project with other tools, products and services. With apps, you can adapt Hygraph to your individual or business needs.

#What can apps do?

With apps, you can extend the out-of-the-box Hygraph functionality and User Interface in various ways. From small custom field extensions to full fledged product integrations, with the App Framework & your custom apps it becomes super easy to extend Hygraph to meet your needs.

Some common use cases are:

  • Adding custom fields to your models
  • Customizing the content editing sidebar to improve the editor experience
  • Triggering actions such as CI builds in third-party systems

For inspiration on what's possible with the App Framework, check out the publicly available apps in our Marketplace.

#Why apps?

Apps offer an improvement over the UI Extensions feature, which will eventually be deprecated. We encourage all users to migrate from UIX to apps.

Why migrate from UIX to the App Framework?

The App Framework offers more flexibility and greater security features:


Creating your own app to be used in the Hygraph platform allows you to have custom fields on your setup, as well as custom functionality on your CMS. You can even group up all your custom elements under one app and install them at once, which greatly simplifies the installation process compared to UI Extensions.

It also makes it possible for you to create custom page views, which was not possible before.


Certain resources are critical for an app to work, and should therefore be hidden from users to prevent accidental removal. Our App Framework offers a permissions system, which allows better control over resources visibility as well as over creating resources on behalf of the user.

With this new permissions system you can create the app establishing which resources should be hidden from users, and also which resources are critical and can't be removed once the app is uninstalled.
