The ''Choose your SitePlan'' pop-up will appear once you click "Publish" inside your project.
You are still able to publish to your custom domain or endpoint for free, with the Vev watermark.
If you wish to publish without the watermark, click "Add site plan", and follow the payment steps. The cost of adding a site plan to a project, to publish without a watermark, incurs a fee of 5$/month per LIVE project.
On the starter plan, you can have up to 3 Site Plans at any given time.
