DriftLess is an AI app builder for founders, indie hackers, agencies, and small teams that want AI speed without losing control of the product scope. It turns a user request into a scoped build, runs the implementation in a real workspace, keeps the preview visible, and uses the Drift Engine to check whether the work still follows the user's latest instruction.

The key difference is scope obedience. A user can expand the plan at any time, and DriftLess treats that as the new boundary. But if the agent invents expansion on its own, DriftLess catches it. For example, a landing page request should not quietly become dedicated menu, gallery, booking, auth, database, or payment-clone routes. A full website can include public informational pages, but not a Calendly clone or Stripe clone unless the user explicitly asks for that.
