Product decision

Prototype vs MVP: what you need at the current stage

A prototype tests flow and understanding cheaply. An MVP tests value through real use.

Short answer

Choose a prototype when the largest unknown is the solution or usability. Choose an MVP when the flow is understood but real use, retention or willingness to pay still needs testing.

Prototype

It can be a clickable mock-up or a manually operated service. It does not need a production backend. Its value is a fast answer to a design question.

MVP

It operates in a real context and delivers value to a selected group. It must be stable, secure and measurable enough for user behavior to be credible.

The common trap

Building a production system to answer a question that a two-day prototype could resolve. Match experiment cost to the value of the uncertainty.
