Proof of Concept FOR Web Apps

Proof of Concept FOR Web Apps

WWG’s application PoC for web apps is proof of concept development that tests the riskiest technical assumption behind your web application before you fund the build. It is for CTOs, founders and product owners who need a decision, not a demo. In two to four weeks you get a working prototype of the key functions, stakeholder testing and a report on feasibility, risks and next steps.

Definition

What is a web application PoC

A web application PoC, or proof of concept, is a short, narrowly scoped piece of engineering that shows whether the technical idea behind a web application works before the development budget is committed. It builds only the most uncertain part, such as an integration, a data flow or a performance limit, and ends in a written verdict on feasibility.

The engagement

A web PoC in concrete terms

Duration
Typically two to four weeks, depending on the complexity of the idea.
Start
After the idea evaluation: the assumptions to test and the success criteria agreed in writing.
Who does the work
WWG engineers specialised in web applications, with a named technical owner for the whole PoC.
What we need from you
A description of the idea and its constraints, access to the systems or APIs involved, one decision-maker, stakeholders available for feedback.
Output
A working prototype of the key functions, test results and a report on feasibility, risks and next steps.
Format
A fixed-scope engagement that closes with a session on the report. No obligation to continue with us.

The price is fixed before we start, based on the perimeter agreed in scoping. For a first development estimate, QuickQuote (https://www.app.qqai.wwg.it/en) gives an order of magnitude in three minutes.

Comparison

A web PoC and the alternatives

A web application can start from four different places, and each answers a different question. This table puts the web PoC next to the web MVP, the full-scale web product and a clickable mockup, so you choose by the risk you need to remove first.

Who it is forTeams with a technical doubt to settle before investing.Teams with proven technology who need to know whether users adopt the product.Companies with a validated product or clear processes to turn into a production system.Teams that need to show an idea and its flow without testing feasibility.
What it coversOnly the riskiest assumption: an integration, a flow, a technical limit.The essential features, in an application real users can use.Architecture, interface, integrations, security, deployment and support.Screens and navigation, with no logic or real data.
DurationTypically two to four weeks.Typically six to ten weeks.Typically four to eight months.Short, because no production code is written.
What you getA working prototype and a report on feasibility, risks and next steps.A first version in use, with KPIs and feedback to decide what to build next.A custom web application in production, with post-launch support.A visual representation to discuss.
When it makes senseWhen you do not yet know whether the idea can be built.When feasibility is known and the open question is the market.When you know what to build and need a system that handles growth.When the doubt is about experience, not technology.

The web MVP and the full-scale web product are separate services in the same web app development area; a web PoC is often the first step towards both.

FAQ

Frequently Asked Questions

An application PoC for a web app is a proof of concept: a small, working piece of software that shows whether the idea behind the application is technically feasible before you invest in full development. WWG engineers build only the uncertain part, such as an integration, a data flow or a performance constraint, test it with your stakeholders and write up the result. It is not a product for end users. It is a documented answer to the question: can this be built, and on what terms?
A web PoC asks whether something can be built; a web MVP asks whether people will use it. The PoC tests technical feasibility in two to four weeks and ends with a report; it does not go to production. The MVP is the first usable version of the web application, with only the essential features, put in front of real users to measure what they do. Start with a PoC when the main risk is technical. Go straight to an MVP when the technology is proven and the open question is the market.
A typical web application proof of concept checks one thing that could sink the project. Examples: whether a browser-based configurator can render product options fast enough to be usable, whether an existing ERP or CRM exposes the data a new portal needs through its API, or whether a real-time dashboard holds up with the data volumes you actually have. Each one is small, built in working code and judged against criteria agreed before the work starts.
A web app proof of concept typically takes two to four weeks, depending on the complexity of the idea and how many assumptions need testing. The exact duration is fixed in the initial evaluation, when we agree what the PoC has to prove and which criteria decide whether it succeeded. A tight perimeter is what keeps a PoC short: anything that does not help answer the technical question stays out.
For web app PoCs WWG engineers use modern frameworks such as React, Angular and Node.js, chosen for the assumption under test. Where possible the PoC uses the stack planned for the real product, so its result also says something reliable about later development. When the question is the stack itself, the PoC can compare two options and the report states which one holds up better in your case.
Yes. A web PoC includes basic UX/UI design, enough to show the functionality and the user flow to the stakeholders who have to judge it. It is not the final design of the application: its job is to make the proof understandable and the feedback meaningful. Full design work, with visual identity and edge cases, belongs to the later stages, the web MVP or the full-scale web product.
The final web PoC report covers the feasibility result, an assessment of the risks found and recommendations for moving forward. It states plainly whether the assumption is confirmed, confirmed under conditions or disproved, and which parts of the work can be reused. It is written for the person who decides on the investment, not only for engineers, and we walk through it with you in a dedicated session.
The price of a web PoC is set before work starts, based on the agreed perimeter: which assumptions to test, which integrations to touch, how complete the prototype needs to be. Scope, duration and price are fixed in writing, so nothing changes halfway through. We do not publish a price list because two PoCs with the same label can need very different work. For a first development estimate, QuickQuote gives you an order of magnitude in three minutes.
A web PoC is run by WWG engineers experienced in web application development, led by a named technical owner who stays your contact from kickoff to the final report. It takes little of your team’s time: a description of the idea and its constraints, access to the systems or APIs involved, one person who can take decisions, and a few sessions where stakeholders try the prototype and give feedback.
A successful web PoC is the foundation for what comes next, usually a web MVP and then a full-scale web product. The report says which components can be carried forward and which should be rewritten to production standards, because PoC code is written to answer a question quickly. The decision is yours: continue with WWG, with another supplier or in-house. If the PoC disproves the idea, you have avoided investing in something that could not work.
A web application PoC is for companies and startups with an idea for a web application that has one uncertain technical point, and no wish to fund a whole build to find out. It is typically requested by a CTO who has to convince a board, a founder who needs something verified before meeting investors, or a product owner choosing between two technical approaches.
