Custom web apps
Bespoke applications designed around your workflow, not forced into a template.
Web Application Development
Custom dashboards, customer portals and internal tools on React, Next.js and Node. Fast, tested and built to scale with real traffic.

Why it matters
Your web app is where the actual work happens, so it has to be quick, reliable and easy to change. We build production applications from an empty repository, or take an existing one that's slowing you down and get it back on track.


What's included
Bespoke applications designed around your workflow, not forced into a template.
Performance budgets and real-device testing so pages stay fast under load.
Payment, CRM, ERP and analytics tools wired in cleanly and reliably.
Role-based access, SSO and sensible defaults that pass a security review.
Rebuild or refactor an ageing app in stages, without a risky big-bang rewrite.
Ongoing releases and monitoring once you're live. We don't disappear.
Web apps that install to the home screen, work offline and send notifications, with no app-store download.
WordPress or a headless CMS set up around your workflow, so your team edits content without touching code.
High-traffic platforms with custom architecture, caching and system integrations built for performance and growth.
Process
We map your goals, users and constraints, then agree a scope and a fixed estimate.
Wireframes, prototypes and a design system, validated with real users.
Two-week sprints with a working demo at the end of every one.
Automated and manual testing across devices before anything reaches users.
A rehearsed release with monitoring in place, not a fingers-crossed deploy.
Ongoing iteration, maintenance and a real person to call when you need one.
Why Infyze
The people who scope your project are the ones who build it, no junior bait-and-switch.
Work is broken into two-week increments you can see and steer, priced before we build.
You never wait months to see progress. Each week ends with something you can click.
The repository, the pipeline and the documentation are yours. No lock-in, no dependency.
We tie the work to numbers that matter to you and report against them honestly.
Support and iteration are part of the relationship, not an upsell once real users arrive.
The stack
We pick tools to fit your product and team, not by fashion, and we document why, so the choice still makes sense a year from now.

FAQ
It depends on scope, but you are not left guessing. After a short discovery call, usually under an hour, we give you a fixed price in writing.
Work is billed in two-week increments you can see and steer. If scope changes partway through, you hear about the cost before we build it, not after.
For a rough ballpark first, try our free cost calculator. It gives you an instant price range and timeline.
As a general shape, a standard custom web app with authentication, a database and a few core workflows lands in the low-to-mid five figures and takes eight to twelve weeks. Simpler internal tools can be faster. Complex platforms with heavy integrations take longer. The discovery call turns that range into a real number.
You get a working demo at the end of every two-week sprint, not a status report. Most web applications reach a usable first release within a couple of months.
We build the core workflow first, the thing your users actually need to do. Real value ships early instead of waiting for everything to be polished. By sprint two or three you are usually clicking through something that resembles the finished product.
A simple internal tool can be usable in four to six weeks. A customer-facing platform with several user roles and integrations takes closer to ten to fourteen weeks.
Either way, you never go more than two weeks without seeing progress you can test yourself. That is how we catch misunderstandings early instead of at the end.
Yes, completely, with nothing held back. You get the repository, the CI/CD pipeline, the hosting configuration and the documentation from day one, all in accounts you control.
There is no lock-in and no proprietary framework that only we can maintain. You can move the project in-house, hire a different agency or commission an independent code audit without our sign-off and without an exit fee.
This matters more than it sounds. Some agencies keep just enough control, such as an account only they can access, that switching away becomes painful on purpose. We do the opposite. We would rather earn a long relationship on the quality of the work than on how expensive it is to leave.
Yes, and this is a substantial part of what we do. We regularly pick up applications that have slowed down, lost their original team or simply stopped moving.
The first step is a short technical audit, usually a few days. We read the codebase, check test coverage and the deployment setup, and tell you honestly what state it is in before proposing anything.
From there we stabilise what is fragile, fix the most urgent bugs and modernise in stages. We avoid a risky big-bang rewrite that pauses feature work for months.
Your product keeps shipping while this happens. If priorities change halfway through, you are never left with a half-finished rewrite and no working product.
Yes. Everything we build is responsive from the first sprint. We design for small screens first and scale up, instead of squeezing a desktop layout down at the end.
We test on real phones, tablets and older browsers. We also set performance budgets, so pages stay quick on a mid-range device over a slow connection, which is where many of your visitors will be.
A progressive web app is a website that behaves like an installed app. It can be added to the home screen, work offline and send notifications, all without an app-store download.
It suits mobile-first users when you want better engagement without store approval or a second codebase. Some things, such as deep hardware access, still need a native app, so we tell you honestly which side of that line your idea falls on.
If it does need a store app, see our mobile app development service.
Yes. We set up a content management system that fits how your team works. That might be WordPress, or a headless CMS paired with a custom front end. Editors can add pages, change copy and publish without waiting for a developer.
We train your team and leave short written guides.
A headless setup gives you faster pages and more design freedom. WordPress is quicker and cheaper to start. We will recommend the one that suits your situation.
Security is built in from the start. We use modern frameworks that handle common attacks by default. We add role-based access and sensible authentication, keep dependencies patched, and review the app for common vulnerabilities before launch.
No honest team promises a system can never be breached. So we document what is protected and what to watch, and we can keep monitoring and patching it after launch.
Yes. For larger platforms we plan the architecture around the expected load from the beginning. That means caching, background queues and a database design that scales. We then load-test before launch so we know where it strains.
Enterprise work also usually means integrating with existing systems, single sign-on and stricter access control. We scope all of that openly up front.
Yes. After launch we keep monitoring, patching and improving the app. You can have anything from occasional fixes to a full support agreement with agreed response times.
