A software prototype costs between $5,000 and $40,000 depending on the type, complexity, and how close to "real" it needs to be. The right prototype saves you from building the wrong product. The wrong prototype wastes money telling you something you could have learned with a conversation.
Let us break down what each type of prototype costs and when each one makes sense.
Types of Prototypes and What They Cost
Design Prototype (Clickable Mockup), $5K to $10K
A visual representation of your product that looks real but has no backend functionality. Users can click through screens and experience the flow, but no data is saved, no accounts are created, and no business logic runs.
Timeline: 1 to 2 weeks.
Tools: Figma, Framer, or static HTML/CSS.
Best for: Validating user flows, testing navigation, getting feedback from potential customers, and pitching investors who need to see something visual.
This is the right starting point for most projects. You can test your core assumptions about user experience without writing a single line of application code. If users cannot figure out how to complete the primary action in your clickable mockup, the problem is your product design, not your technology.
Functional Prototype (Working MVP), $15K to $40K
A real application with actual functionality, but scoped to the absolute core feature set. Users can sign up, perform the primary action, and see results. The code is production quality but the feature set is deliberately minimal.
Timeline: 4 to 8 weeks.
Stack: Typically TypeScript, React/Next.js, Supabase, deployed to a real URL.
Best for: Validating that people will pay for your product, testing technical feasibility of your core feature, and generating real usage data.
This is what most people mean when they say "prototype" but it is really an MVP. The distinction matters because an MVP is designed to evolve into a real product, while a throwaway prototype is designed to be discarded. We build prototypes that become products because rewriting from scratch is almost always a waste of money.
Technical Proof of Concept, $10K to $25K
A prototype that proves a specific technical capability works. Not pretty, not user friendly, but functional. This is for projects where the core risk is technical, not market based.
Timeline: 2 to 4 weeks.
Best for: AI/ML integration feasibility, complex data processing pipelines, hardware/software integration, real time performance requirements, and third party API capabilities.
If your product depends on an AI integration that needs to process 10,000 documents per hour with 95% accuracy, you need to prove that works before building the full product around it. A technical proof of concept answers the question: "Can we actually build this?"
What Drives Prototype Cost
Fidelity. A rough wireframe prototype costs a fraction of a pixel perfect design with animations. Higher fidelity is more convincing for investor demos but more expensive and slower to iterate.
Number of user flows. A prototype that demonstrates one primary flow (sign up, do the thing, see the result) costs less than one that covers onboarding, core features, settings, admin panels, and edge cases. Resist the urge to prototype everything. Focus on the flow that proves your hypothesis.
Technical complexity. A prototype for a CRUD application is cheaper than one for a real time collaborative editor or an AI powered analytics tool. If the core feature requires complex backend logic, the prototype needs a real backend, which significantly increases cost.
Data requirements. Some prototypes need realistic data to be meaningful. A prototype for a financial dashboard with dummy data that shows the same three numbers on every screen does not actually test anything. If your product value depends on data, the prototype needs real or realistic data, and generating that data is a project in itself.
The Most Expensive Mistake: Building Too Much
The single most common mistake we see with prototypes is scope creep. A founder comes in wanting to validate their core idea, and by the end of the scoping call, they have described a full product with 40 features, three user roles, and an admin dashboard.
A prototype should answer exactly one question. Will users complete this core action? Can this technology handle our requirements? Will people pay for this specific feature? If your prototype tries to answer five questions simultaneously, it will take five times longer, cost five times more, and give you ambiguous answers to all of them.
Prototype vs MVP vs Full Product
Understanding the progression prevents overspending at each stage:
Prototype ($5K to $15K): Proves the concept works. Answers a specific question. May or may not use real code.
MVP ($15K to $40K): Smallest real product people will pay for. Production code, but minimal features. Designed to collect data about what to build next.
Full Product ($40K to $200K+): Everything the product needs to compete in the market. Multiple features, polished UX, integrations, and scalability. Read our full cost breakdown for this stage.
Spending $40K on a prototype when a $5K design mockup would have answered your question is waste. Spending $5K on a mockup when you need working code to test technical feasibility is also waste. Match the prototype type to the question you need answered.
When to Skip the Prototype Entirely
Sometimes prototyping is unnecessary:
You have deep domain expertise. If you have worked in the industry for 15 years and know exactly what the product should do, you might be better served going straight to an MVP. The risk is not "will people want this?" but "can we build it efficiently?"
The market is proven. If competitors exist and are making money, you do not need to validate the concept. You need to validate your differentiation, which often requires a functional product, not a prototype.
Time is the constraint. In a competitive market where three other teams are building the same thing, spending two months prototyping means arriving last. Sometimes the right move is to build the MVP directly and iterate based on real user feedback. We took this approach with GameLootBoxes, going straight to a functional product because the market window was narrow and the concept was already validated.
How We Handle Prototypes at Veld
We build prototypes that convert into products. Our full stack team uses production grade tools and architecture from day one, so the prototype code becomes the foundation of the real product instead of getting thrown away.
A typical prototype engagement starts with a 1 week discovery sprint where we define the hypothesis, scope the minimum viable test, and design the user flow. Then we build for 2 to 6 weeks depending on complexity.
