What is web application development?
Web application development is the building of software that runs in a browser and does real work — a customer portal, an internal dashboard, a marketplace, a SaaS product. It differs from a website in that people log in and change things, so it needs accounts, permissions, state and a database behind it.
The part that decides whether it succeeds is rarely the feature list. It is whether the app loads quickly on an ordinary phone on an ordinary connection, whether the sign-up survives a bad network, and whether the second screen is as considered as the landing page. Those are engineering decisions made early, and they are expensive to retrofit.
We build on React and Next.js because they are widely known, so your team or your next agency can maintain what we hand over. Nothing here is a framework only we understand.
— What we build —
Four kinds of web application.
Different shapes, one engineering standard. Each is scoped and priced before a line of code is written.
Every release is checked on a real phone before it reaches production, not only in a desktop browser.
— What you get —
Engineering standards, not optional extras.
These four are in every build. They are the difference between an app that launches and an app that lasts.
01
Performance budget
We set a load-time target on a mid-range Android phone and hold the build to it. Most web apps are tested only on the developer’s own machine, which is why they feel slow to everyone else.
02
Accessibility as a baseline
Keyboard navigation, focus states, colour contrast and real form labels. Cheap to do while building, expensive to add later, and it makes the app better for everyone.
03
Tests where it matters
Automated coverage on sign-up, checkout, permissions and anything touching money. Not a coverage percentage for its own sake — the paths whose failure you would hear about.
04
Deployment and monitoring
Continuous deployment, error tracking and uptime alerts wired in before launch, so a broken release is something you learn from a dashboard rather than from a customer.
— How we work —
Six to fourteen weeks, start to launch.
The range is scope, not uncertainty. Your number is fixed once discovery is done.
01 · Discover
Flows and constraints
1 week
Who logs in, what they need to accomplish, and what has to integrate. We map the screens before designing any of them.
02 · Design
Interface and data model
1–2 weeks
Key screens designed and the schema agreed. Design is part of the build here, not a separate engagement you commission twice.
03 · Build
Two-week sprints
4–10 weeks
A working, deployed environment at the end of each sprint, on a URL you can open and send to a colleague.
04 · Harden
Performance and testing
1 week
Load times measured on real devices, accessibility pass, security review, and the automated test suite finished.
05 · Launch
Production and handover
~1 week
Go-live, monitoring, documentation and a walkthrough for whoever maintains it next.
— Honest qualification —
Who this is for.
Saying no early is cheaper for both of us than discovering the mismatch in week three.
A good fit
- People log in and change things — it is an application, not a brochure site
- You want it maintainable by any competent React team afterwards
- Speed and mobile experience matter, because your users are not on office broadband
- Someone on your side can answer product questions quickly
Not a fit
- A marketing site or blog — a CMS will serve you better and cost far less
- A no-code tool already does the job; we will tell you when one does
- You want a fixed price on requirements that are still being discovered
- The plan is to take whichever quote is lowest and assume quality
Have a spec, or just a problem?
Either is fine. Send the spec if you have one, or describe what people need to do and we will shape it into something you can price and schedule.
Real questions
Common Questions
The questions we get asked most, answered directly.
How much does web application development cost?+
We price per project rather than per hour, with the figure agreed in writing before work starts. Scope is what moves it: the number of distinct user roles, whether payments are involved, how many external systems it integrates with, and whether it needs to be multi-tenant. A single-role internal dashboard is the smallest engagement; a two-sided marketplace with payments and payouts sits considerably higher. A scoping call and a written proposal cost you nothing.
How long does it take to build a web application?+
Six to fourteen weeks for most projects, measured from signed scope to production. A focused internal dashboard lands near the bottom of that range. A marketplace or SaaS product with billing, multiple roles and third-party integrations lands near the top. Discovery and design add one to three weeks before the build clock starts, and we would rather spend that time than discover in week eight that the wrong thing was built.
Which technology stack do you use?+
React with Next.js on the front end, Node.js or NestJS on the back end, PostgreSQL for data, deployed on AWS or Vercel. We choose these because they are mainstream: you can hire for them anywhere, and any competent agency can take over the codebase. We do not build on a proprietary framework, and we will use something different when your existing team already runs a different stack well.
What is the difference between a website and a web application?+
A website presents information; a web application lets people do things. The moment users sign in, submit data, see something personalised, or change a record, you have an application — which means accounts, permissions, a database, validation and a security model. That distinction matters commercially, because an application costs several times what a comparable-looking website costs, and a CMS that renders a beautiful site will not carry an application safely.
Will it work properly on mobile?+
Yes, and we test on real devices rather than a resized desktop browser. We set a load-time target on a mid-range Android phone at the start and hold the build to it. This matters more in India than most vendors admit: a large share of traffic arrives on mid-tier phones over variable connections, and an app tuned only on a developer’s laptop will feel broken to those users while looking perfect in the demo.
Can you take over an existing web application?+
Often, yes. We start with a short paid audit of the codebase, the infrastructure and the test coverage, and report back on what is salvageable and what is not. Sometimes the honest answer is that a rewrite costs less than continuing, and we will show the reasoning rather than assert it. Taking over someone else’s code is normal work; inheriting it without an audit is how estimates go wrong.
