In the light of the recent banning of Stacket I asked the Webflow support about the method mentioned above:
Any service that uses a “page scraping” technology is against our Terms of Service. I would not recommend using any service that is “page-scraping” or sometimes called “website-scraping”.
Also…these services are probably not using official Webflow APIs to transfer your data. As such, we cannot vouch for your data’s security/privacy/authenticity and your site may be exploited or compromised. Further, we cannot guarantee that their service will continue to operate without interruption.
