Turn off the live preview

Turn off the live preview is Lovable's Editor feature: You can now turn off the live preview if it is slow for a big project.

You can now turn off the live preview if it is slow for a big project. In Project settings → General → Preview , switch off Live preview , and the preview panel shows the latest built version of your app instead of running it on a live dev server. It updates when Lovable finishes a change rather than while it works. Lovable still builds and tests your changes, and still sees runtime errors, console output, and network requests from the built preview. Holding Shift while selecting Refresh no longer restarts the preview environment. The setting applies to the whole project: everyone who opens it sees the built version, and project editors can turn it back on at any time.
