Step 3
Skip custom domains
Your public URL is https://yaff.io/yourname. There is no settings field, DNS flow or Pro-only domain mapping in the app.
What Pro actually changes
Pro is $99/mo with a 0% platform fee and a 1,000-supporter cap. It does not gate branding, video, chat or ebooks. Those are available on Starter.
