About Wix Harmony and Apps

Wix Harmony is Wix's new AI-powered site editor. With Harmony, the way apps and extensions work across Wix is evolving. This overview explains app compatibility in Harmony, what's changing, and your options for supporting users across all Wix editors and frameworks.

Note: For information about site development with Wix Harmony, see About Wix Harmony. For Blocks-specific information, see About Wix Harmony and Blocks.

App compatibility at a glance

Apps can be installed in Harmony, though the UI and App Market experience differs from other editors. Due to architectural and technology updates, some app types are only available in certain editors.

What this means for existing apps

Your app's availability in Harmony depends on the types of extensions it includes:

  • Supported extensions: Your app works in Harmony with no changes required.
  • Unsupported extensions: Your app works on Wix Editor and Wix Studio, but can't be installed by Harmony users. To reach Harmony users, rebuild unsupported extensions using the Wix CLI for Apps or self-hosting.
  • Partial support (iFrames): If your app uses legacy iFrame widgets or pages, test your app thoroughly in Harmony. If you encounter issues, reach out to us for help.

Recommendations for new apps

When building a new app, use frameworks supported in Harmony:

  • Wix CLI: Build app extensions using your preferred IDE, with local development, testing tools, and full control over your code. Learn more in the Wix CLI documentation.
  • Self-hosting: Use your own infrastructure for backend, site, or dashboard extensions. Learn more about self-hosted extensions.

Test your app

We recommend testing your app in Harmony to ensure it works as expected. Create a Harmony development site to test your app's functionality and user experience.

To learn more, see Test Your App on a Free Premium Site.
