Divi 5 uses speculative prerendering to dramatically reduce - or eliminate - load times when navigating in and out of the builder. By predicting where you're headed and loading the destination in the background before you click, the builder feels instant. This article explains how it works, where it applies, and how to control it.
What Is Speculative Prerendering?
Speculative prerendering is a browser-level feature that loads a page in the background before you navigate to it. Divi 5 uses your mouse movement as a signal - when your cursor moves toward a navigation target, Divi starts prerendering that destination. By the time you click, the page is already loaded.
Divi only prerenders destinations within its own domain, so this applies specifically to the builder experience - not your visitors' front-end browsing.
โ ๏ธ Note: Browser support: The Speculation API is currently supported by Chromium-based browsers - Chrome, Edge, Opera, and others. Safari and Firefox have not implemented it yet. Users on those browsers won't see the benefit until support is added.
Where Speculative Prerendering Applies
Entering and exiting the builder
When you move your mouse toward the Edit with Divi button in the admin bar, Divi starts prerendering the builder immediately. Click the button, and the builder opens instantly. The same applies in reverse - exit destinations are prerendered as you leave, so bouncing between the builder, the WordPress Editor, and the front end happens without delay.
Navigating between pages via the Command Center
Prerendering is also built into the Command Center (Cmd+K / Ctrl+K). As soon as a navigation command becomes active - whether you're typing a page name or selecting a result - Divi starts prerendering that destination. Press Enter, and the page is already there.
Performance on Slower Hosting
Speculative prerendering doesn't require fast hosting to be useful. If your builder normally takes 5 seconds to load and Divi starts prerendering 1.5 seconds before you click, you're still shaving 1.5 seconds off that load time - a 30% improvement without any configuration.
Enabling and Disabling Prerendering
Speculative prerendering is enabled by default. Each prerender counts as a page request on your server. If server resource usage is a concern, you can turn it off in the builder settings. To disable it:
Open any page in the Divi 5 Visual Builder.
From the left sidebar, click on the Builder Settings icon

Toggle off Speculative Prerendering.
Disabling it restores standard load behavior with no other impact on builder functionality.
