About Wix Blocks in Wix Harmony and Wix Studio Two

Wix Harmony is Wix's AI-powered site editor. Wix Studio Two is built on the same architecture as Harmony and adds a coding environment for site developers. Studio Two is a separate editor from Wix Studio. Both editors use a technical architecture that's different from previous editors, and this new foundation changes how apps and extensions work.

Wix Blocks apps aren't compatible with sites built on Wix Harmony or Wix Studio Two. Your existing Blocks apps 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 and Studio Two mean for Blocks developers and walks you through your options for building and supporting apps across the different Wix editors.

Note: If you're extending Wix sites with Velo or the JavaScript SDK, see About Wix Harmony. For extending Studio Two sites, see About Extending Websites with Studio Two.

What this means for existing apps

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

Dashboard extensions only: Your app works in Harmony and Studio Two with no changes required. However, for new apps, we recommend using the Wix CLI or self-managing to build apps that work across all Wix editors.
Site widgets or site plugins: Your app works on Wix Editor and Wix Studio but not in Harmony or Studio Two. To support Harmony and Studio Two users, rebuild these extensions with the Wix CLI or self-managing.

Build site extensions for Wix Harmony and Wix Studio Two

To create site extensions that work in Harmony and Studio Two, use one of these approaches.

Wix CLI

Build app extensions using your preferred IDE, local development, and full control over your code. The CLI supports these site extensions:

Site widgets and embedded scripts, which work in all Wix editors.
Editor React Components, which work only in Harmony and Studio Two.

Learn more in the Wix CLI documentation.

Self-managed

Deploy your app on your own infrastructure and tech stack, and register its extensions in your app's dashboard. Self-managed apps support these site extensions, which work in all Wix editors:

For private app developers

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 or Studio Two, 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-managing.
