UX/UI Design: Foundations to Practice · Wireframing and Prototyping
Prototyping Without Code
A meaningful prototype does not require writing production code, and understanding what a no-code or low-code prototype can and cannot substitute for helps a founder move quickly without either over-investing early or under-testing a genuinely risky assumption.
Building a prototype directly in production code, rather than a dedicated, faster prototyping approach, tends to slow down exactly the rapid iteration a prototype is meant to enable, since real code carries genuine technical constraints and a natural reluctance to discard work that a quick, disposable prototype specifically avoids; a prototype is meant to be cheap enough to throw away entirely if it reveals the underlying idea does not work, a property real production code structurally resists.
- A prototype should not start as real production code, since real code resists the disposability a prototype needs and slows down rapid iteration.
- Linked static screens with tappable hotspots are a legitimate technique for testing an entire flow's navigation logic without any real functionality behind individual screens.
- The Wizard of Oz technique has a real person manually perform complex functionality behind the scenes, testing user reaction before investing in actual development.
- A no-code prototype eventually reaches a genuine limit once the open question requires testing something only a real, working implementation could actually reveal.
