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.
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 so there are no surprises once work is underway. Work is billed in two-week increments you can see and steer, and if scope needs to change partway through, you hear about the cost before we build it, not after. For a rough ballpark before we even talk, try our free cost calculator: it walks you through project type, complexity and features and gives you an instant price range and timeline. As a general shape, a standard custom web application with authentication, a database and a handful of core workflows typically lands in the low-to-mid five figures and takes eight to twelve weeks, though simpler internal tools can be faster and more 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, and most web applications reach a usable first release within a couple of months depending on scope. We deliberately build the core workflow first, the thing your users actually need to do, so real value ships early rather than being held back until everything is polished. By sprint two or three you are typically clicking through something that resembles the finished product, even if secondary features are still coming. For a simple internal tool this can mean a usable version in four to six weeks; for a more complex customer-facing platform with several user roles and integrations, expect closer to ten to fourteen weeks. Either way, you never go more than two weeks without seeing tangible progress you can test yourself, which is what lets us 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 rather than ours. There is no lock-in and no proprietary layer or framework you are quietly dependent on that only we can maintain. If you want to move the project to an in-house team, hire a different agency, or just want an independent audit of the code, you are free to do any of those without needing our sign-off or paying anything extra to leave. This matters more than it sounds: plenty of agencies keep just enough control, an account only they can access, a deploy process only they understand, that switching away becomes painful on purpose. We do the opposite deliberately, because we would rather earn a long relationship on the quality of the work than on how expensive it is to walk away.
Yes, and this is a substantial part of what we do. We regularly pick up applications that have slowed down, lost their original development team, or simply stopped moving forward, and get them back on track. The first step is always a short technical audit, usually a few days, where we read the existing codebase, check test coverage and deployment setup, and tell you honestly what state it is actually in before proposing anything. From there we stabilise what is fragile, fix the most urgent bugs, and then modernise in stages rather than attempting a risky big-bang rewrite that pauses feature work for months. This staged approach means your product keeps shipping and users see continuous improvement, rather than silence while we rebuild everything behind the scenes. If priorities change halfway through, you are never left with a half-finished rewrite and no working product.
