Wix Harmony is Wix's new AI-powered site editor, built on a technical architecture that's different from previous editors. While Harmony introduces powerful new AI-driven features for site creation, its new foundation also changes how apps and extensions work.
Wix Blocks apps aren't compatible with sites built on Wix Harmony. Your existing Blocks apps will continue to work and remain available for purchase on the Wix App Market for Wix Editor and Wix Studio sites.
This article explains what Harmony means for Blocks developers and walks you through your options for building and supporting apps across the different Wix editors.
Note: If you're developing Wix sites with Velo or the JavaScript SDK, see About Wix Harmony.
The following table shows which Blocks extensions work in each editor.
Note: App discovery in Harmony works differently than in other editors.
| Extension type | Wix Harmony | Wix Editor & Wix Studio |
|---|---|---|
| Dashboard pages | ✓ | ✓ |
| Dashboard plugins | ✓ | ✓ |
| Dashboard modals | ✓ | ✓ |
| Site widgets | — | ✓ |
| Site plugins | — | ✓ |
Your app's availability in Harmony depends on the types of extensions it includes:
To create site extensions that work across all Wix editors, including Harmony, use one of these approaches:
If you've built a private app with Blocks for specific Wix sites, the same compatibility rules apply. Your app continues to work on sites built with Wix Editor and Wix Studio. However, if your client creates a new site using Harmony, your app won't be available on that site.
To ensure your app works across all editors, consider rebuilding site extensions with the Wix CLI or self-hosting.
