What keeps most people where they are is rarely the $16 a month — it is the thought of typing everything in again on a Tuesday night. So paste the address you have now, and your brief comes back filled in. You correct it instead of writing it.
Every line above is a guess read off your page — the brief opens with them filled in and you change whatever we got wrong. Nothing is saved until you submit it.
Nothing, until you say so. Yours keeps running while we build the new one, and you see it finished on a private link before anything points anywhere. When you press go, we move the domain — or you keep it where it is and just repoint it, whichever is less frightening. If you decide against it, you have lost ten minutes and paid nothing.
This is not all-or-nothing, and we would rather say so than lose you on a false choice.
Only one reason, and it is not the design: on a builder, every future change is yours. New hours in March, a price rise, the photo from last week — each one is you, at a laptop, at ten at night. Here it is an email, two a month included, and $10 rather than $16 to $25. If you enjoy building websites, genuinely stay where you are — you will miss the control. The honest comparisons say where each of them beats us.
