Should I build a prototype or an MVP first?

Usually a prototype first — it settles the design cheaply — then an MVP built from that blueprint, which carries less rework than designing while building.

Where does Koryvant fit?

Koryvant is the prototype stage: the design-complete blueprint before the MVP build. Koryvant is the design-complete blueprint layer, not a full-app builder. There is no backend, no database, and no running full-stack app.

Prototype vs MVP: what each one is for

A prototype and an MVP are often used interchangeably, but they answer different questions. A prototype tests whether the design and flow are right; an MVP is a real, minimal product that tests whether the market wants it. Knowing which you need saves building the wrong thing.

What a prototype is for

A prototype validates the design: the screens, the flow, the feel. It is cheap to make and cheap to change, because it has no real backend and no real data — it models the product rather than running it.

You reach for a prototype to answer "is this the right product to build," to align a team, to test with users, or to show investors, all before committing to a build.

What an MVP is for

An MVP — a minimum viable product — is a real, working product with the smallest scope that delivers value. It has a backend, real data, and real users, because its job is to test demand in the market, not just the design.

An MVP costs more than a prototype because it actually runs. That cost is worth paying once the design is settled, and wasteful before it is.

Prototype first, then MVP

The two are stages, not rivals. Settle the design in a prototype, then build the MVP from that decided blueprint, and the build carries far less improvisation and rework.

Koryvant sits at the first stage: it generates the design-complete prototype so the MVP that follows is built from a decided design rather than designed while it runs.
