Thanks for the feedback @b-claeskens and @wmsagent .
Since Editor X and Wix are both cloud-based SaaS (Software as a Service), in order for it to work properly, it needs to be hosted and operated on Wix’s servers.

We have been working on opening our APIs and I’ll definitely forward being able to export the HTML, CSS, assets and Javascript or perhaps parts of it from Editor X to perhaps backup the code and project so thanks for the feedback.
