No, you do not need to upgrade or purchase an additional plan in order to use your own URL and free hosting with your old website in Webflow. Webflow offers free hosting on their subdomain (yoursite.webflow.io), which you can use to host your old website or any new websites you create.
To use your own domain name with Webflow, you will need to upgrade to a paid plan. The two plans that offer custom domain hosting are the Lite plan and the Pro plan. The Lite plan allows you to connect up to 10 custom domains, while the Pro plan allows for an unlimited number of custom domains.
By upgrading to one of these plans, you'll be able to host your old website on your own URL. Additionally, if you plan to create additional sites in the future, you can use the same plan to host those sites as well. This makes it cost-effective and convenient, especially if you are managing multiple websites.
It's worth noting that while the hosting is free, there may be additional costs associated with registering a domain name from a domain registrar. These costs vary depending on the domain registrar and the specific domain name you choose.
In summary, to use your own URL and free hosting with your old website in Webflow, you'll need to upgrade to a paid plan (Lite or Pro). Upgrading to a plan also allows you to host multiple sites in the future, making it a great option for managing multiple websites.
