The Real Math Behind Buy-Once vs. Subscription for Builders

Subscriptions are a great way to ship a prototype on day one

Lovable, Bolt, and v0 collapsed the distance between an idea and a running URL. That is a real enable: in an afternoon you go from a Notion doc to a deployed app with auth, a database, and a Stripe webhook. For the first thirty days of any product — when the question is "does anyone want this" rather than "does this scale" — a metered sandbox is the fastest tool we have. I am not going to pretend otherwise.

The math starts to bend when the prototype is no longer a prototype.
