Alpha Page Builder
We have released an alpha version of our new Page Builder. The new Page Builder completely reimagines the page-building experience and adds live-rendered preview thumbnails.
Eventually, the Alpha Page Builder will replace the current editor. In the meantime, if you switch to the Alpha Page Builder, you can easily revert to the Legacy Editor.
The Alpha Page Builder only works with Slice Machine projects, which means that it is compatible with Next.js and Nuxt.
Some features are not yet supported in the new Page Builder. We're working towards adding the following features:
- Adding to a release
- Scheduling
- Revision history
- Integrations
- User roles
- Links to media within rich text
- Links to media using link fields
We are currently inviting users to sign up for the waitlist. We will let you know we have enabled the new Page Builder for your repository.
Once you have access to the Alpha Page Builder, your documents will automatically be opened with it.

In order to enable this feature for your content team you will need to do three things:
To enable live previews, first ensure that you have the slice simulator installed: check the slicemachine.config.json
file at the root of your project. The file should include a "localSliceSimulatorURL"
property like "https://localhost:3000/slice-simulator"
. Your project should include a corresponding page component.
Your project must be deployed. Once deployed, you can check to ensure that the slice simulator is working by visiting your-site.com/slice-simulator
. You should see a page like this:

Copy–paste the URL for that page into the configuration for the Page Builder. Now you should have live previews working.
Rest assured, you won’t lose any of your current work when you upgrade to the new Page Builder. Your existing documents will be available for you to edit in the new Page Builder. Any changes you make in the new Page Builder will persist if you ever revert to the Legacy Editor.
As our first release is an alpha we do not support all the features of the current Page Builder. So, if there is something you want to do using the Legacy Editor you can easily switch back.
