What is prototype development?

Prototype development creates a limited artefact to test a specific product, interaction, workflow, or technical assumption before production. The work includes the question, prototype boundary, test method, evidence, limitations, and decision. Its value comes from changing a decision, not from looking like finished software.

What is the difference between a clickable and functional prototype?

A clickable prototype simulates screens, states, and navigation, usually without durable backend behaviour. A functional prototype runs enough real logic, data, or integration to test a bounded workflow or feasibility question. Both omit production security, scale, reliability, operations, and support unless explicitly scoped for the test.

How is a prototype different from a proof of concept or MVP?

A prototype usually tests an experience or workflow. A proof of concept tests whether a technical approach can work under stated conditions. An MVP is production software used by real users to create value and learning. The labels overlap in casual use, so we define the decision, evidence, and operating boundary before choosing one.

What does prototype development cost?

A focused clickable prototype starts around $5,000. A functional prototype starts around $10000 when it needs limited logic, data, or an integration. Several concepts, external participant recruitment, complex hardware or AI evaluation, high-fidelity content, or production-quality foundations add scope. Final price follows a defined question and method.

What happens after the prototype is tested?

The evidence may support production discovery, an MVP, a changed concept, another targeted test, an existing product, deferral, or stopping. You own the prototype and findings. If production is justified, it is scoped separately because a test artefact should not silently become a live system handling real users and data.

Prototype Development Services

Prototype development that answers one expensive question before production.

Build a clickable or functional test artefact for a specific user, workflow, concept, or feasibility question. RaftLabs defines what the prototype must prove, how it will be tested, and what evidence supports the next decision. A prototype is deliberately not production software, an MVP, or a promise of demand.

The brief

Start with what is not working.

Good software decisions begin with the constraint, not a list of features or a preferred technology.

Are you about to fund production software before a user, stakeholder, or technical dependency has tested the riskiest assumption?

Is an impressive demo being treated as evidence without a defined question, representative participants, or decision threshold?

Plain answer

Prototype development creates a disposable or limited-life artefact to test one product, workflow, interface, or technical question before production. RaftLabs defines the hypothesis, builds a clickable or functional prototype, tests it with agreed evidence, and records the decision. Clickable prototypes start around $5,000; functional prototypes start around $10000. Neither is production software.

A prototype is useful only if it can change the decision.

A polished walkthrough can win agreement without testing comprehension, behaviour, operational fit, or technical feasibility. That is theatre, not evidence. Before building, decide what would make the team proceed, revise, or stop, and who or what can provide credible evidence.

Then build only enough artefact to expose that assumption. Everything else is detail the test does not need.

Engagement facts

starting point for a clickable prototype: $5K; One defined product or workflow question

starting point for a functional prototype: $10K; Limited logic, data, or integration

typical question-to-decision window: 2-6 weeks; Method and participant access affect timing

RaftLabs has shipped more than 100 software products since 2015, which helps us recognise where test artefacts differ from production systems. That company-wide record does not prove a prototype will create demand, persuade an investor, or predict product success. We report what the chosen method and participants support, plus the limitations that remain.

A prototype needs one decision, not a backlog

A fit

One user flow, interaction, stakeholder concern, or technical path could materially change whether or what you build.

You can identify representative participants, data, systems, or conditions and agree what evidence would change the decision.

The team accepts that prototype code and infrastructure may be disposable after the test.

Not a fit

The problem, user, and product boundary are broadly uncertain and need product discovery before a targeted test.

You already have validated scope and need production software for real users, real data, and ongoing operations.

You have an existing AI-built or no-code prototype and need an audit-led path to production rather than another test artefact.

Clickable, functional, proof of concept, or MVP

The right format follows the uncertainty. Testing whether users understand a navigation model rarely needs backend logic. A clickable screen cannot prove that an integration or model will work. Real customers and sensitive data belong in a service with production controls, not an unsupported prototype.

Decision guide

Match the artefact to the evidence

Artefact	Use it to test	Do not infer
Clickable prototype	Concept, content, interaction, navigation, and workflow comprehension	Technical feasibility, security, reliability, or operational readiness
Functional prototype or PoC	Bounded logic, integration, model, data, or end-to-end feasibility	Production scale, maintainability, compliance, or market demand
Minimum viable product	Value and behaviour with real users in a supported production service	Guaranteed retention, scale, or product-market fit
Production hardening	Whether an existing working build can safely support real operation	That every prototype should be preserved or rewritten

What a credible prototype includes

The artefact is only one deliverable. A future reviewer should be able to understand the assumption, who or what was tested, what was simulated, what happened, and why the team made the resulting decision.

Deliverables

A bounded prototype engagement

01
Decision and hypothesis
The specific question, current belief, target user or technical condition, available evidence, success and stop signals, decision owner, time limit, and non-goals.
02
Representative test path
Critical screens, states, content, scenarios, sample data, role or participant context, accessibility needs, and only the branches required to expose the assumption.
03
Appropriate fidelity
Clickable interface for experience questions, or limited backend, model, device, and integration behaviour for feasibility questions, with simulated and real parts labelled clearly.
04
Test method and evidence
Recruitment criteria or technical conditions, facilitation guide, tasks, observations, measurements, failures, counter-evidence, limitations, privacy boundaries, and consent for any participant research.
05
Decision handover
Prototype source, assets, method, findings, unresolved risks, recommendation, and the implications for discovery, production scope, procurement, another test, or stopping.

Build just enough to learn honestly

From risky assumption to recorded decision

Phase 1
01
Define the question
Name the decision, hypothesis, audience, current evidence, prototype type, fidelity, test method, success and stop signals, constraints, non-goals, owners, and deadline.
Phase 2
02
Design the test path
Map only the screens, states, data, integration, scenario, accessibility, facilitation, and instrumentation needed to expose the assumption without implying production readiness.
Phase 3
03
Build and test the prototype
Create the bounded clickable or functional artefact, rehearse the method, observe representative sessions or feasibility cases, capture evidence, and correct test-blocking defects.
Phase 4
04
Record the decision
Hand over the prototype, source, method, observations, limitations, findings, unresolved risks, and recommendation to proceed, revise, test again, buy, defer, or stop.

Risk

What a prototype must not pretend to prove

Five positive reactions prove demand: Participant context and method matter. Separate comprehension, preference, stated intent, observed behaviour, willingness to pay, and broader market evidence.
A working integration proves production feasibility: Record data, environment, load, error, security, cost, licensing, vendor, and operational limits. A successful test under narrow conditions stays narrow evidence.
Prototype code is almost production code: Label disposable architecture, hard-coded data, incomplete access control, missing tests, limited observability, manual steps, and unsupported dependencies before handover.
High fidelity means high certainty: Visual polish can make assumptions feel resolved. Keep the question, method, counter-evidence, uncertainty, and next decision visible alongside the artefact.

Scope and price

A focused clickable prototype starts at $5,000.

Start with one decision, hypothesis, representative path, appropriate fidelity, test method, evidence, limitations, and a recorded recommendation.

These are indicative starting points, not quotes or guarantees of demand, investment, feasibility, compliance, production readiness, or product success. Scope is fixed after the question and method are agreed.

Starting investment

Starts at $5,000

Functional prototypes start around $10000. Most focused engagements take 2 to 6 weeks; participant recruitment, several concepts, hardware, AI evaluation, or complex integrations add work.

The prototype is labelled honestly

Simulated, disposable, limited, and untested parts stay explicit in the artefact and handover.

The evidence remains portable

You own the source, assets, method, findings, limitations, and recommendation whether RaftLabs builds the next phase or not.
