Pricing

What should an MVP prototype cost in 2026?

Short answer: a validation prototype should cost hundreds, not tens of thousands. The confusion comes from mixing up a prototype that proves demand with a production app that serves customers.

If you ask three agencies to quote an "MVP," you will get three wildly different numbers — often $15,000 to $80,000 and timelines of two to four months. That is because most of them quote a small production system, not a test. Before you sign anything, separate the two jobs.

Two very different things get called an "MVP"

• A validation prototype: a clickable version of the core workflow built to learn whether the idea is worth real money. Days to build. Hundreds of dollars.
• A production MVP: a deployable app with real accounts, payments, data, and security. Weeks to months. Tens of thousands of dollars.

Paying production prices to answer a validation question is the most common early mistake founders make. You can answer "should this exist" long before you pay to build the thing that exists.

Why agency quotes balloon

• Open scope: "we will figure it out as we go" is billed by the hour, and hours multiply.
• Production concerns too early: auth, billing, and infrastructure that a test does not need.
• Revisions with no boundary: endless feedback loops that have nothing to do with the core question.

What a validation prototype actually needs

To get real signal you need a believable, clickable core workflow, realistic copy, mocked data, and a clear read on what is weak. That is it. Everything else is decoration until the idea earns a real build. This is the same reasoning behind choosing a clickable prototype over a static mockup.

A sane fixed-scope benchmark

A focused, fixed-scope prototype with an honest evaluation should land around a few hundred dollars and a week of calendar time. That is exactly how Promptlaiy is priced: a flat $499 for one clickable workflow, a blunt evaluation, a test plan, one revision, the source ZIP, and a 60-day hosted preview. Optional add-ons — a $250 domain launch and $49/month managed hosting — exist only if you decide to go further.

When to spend the bigger budget

Spend production money after a prototype gives you a clear pass. If you have not yet validated the idea with real users, a $40,000 build is just an expensive way to find out you were wrong.
