Custom web apps
Bespoke applications designed around your workflow, not forced into a template.
Web Application Development
Web applications built to run your business.
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
A web development partner that turns a rough idea into software you can run on.
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.
- Component-driven front ends with accessibility built in
- Typed, tested APIs that stay safe to change
- Deployed on infrastructure you actually control
What's included
Everything your web development engagement covers.
Speed & Core Web Vitals
Performance budgets and real-device testing so pages stay fast under load.
Integrations
Payment, CRM, ERP and analytics tools wired in cleanly and reliably.
Auth & security
Role-based access, SSO and sensible defaults that pass a security review.
Legacy modernisation
Rebuild or refactor an ageing app in stages, without a risky big-bang rewrite.
Support & iteration
Ongoing releases and monitoring once you're live. We don't disappear.
Process
How your web development project runs.
- 01
Discovery
We map your goals, users and constraints, then agree a scope and a fixed estimate.
- 02
Design
Wireframes, prototypes and a design system, validated with real users.
- 03
Build
Two-week sprints with a working demo at the end of every one.
- 04
Quality assurance
Automated and manual testing across devices before anything reaches users.
- 05
Launch
A rehearsed release with monitoring in place, not a fingers-crossed deploy.
- 06
Support
Ongoing iteration, maintenance and a real person to call when you need one.
Why Infyze
Why teams choose us for this.
A senior team, no hand-offs
The people who scope your project are the ones who build it, no junior bait-and-switch.
Fixed scope, honest estimates
Work is broken into two-week increments you can see and steer, priced before we build.
A working demo every Friday
You never wait months to see progress. Each week ends with something you can click.
You own everything
The repository, the pipeline and the documentation are yours. No lock-in, no dependency.
Results we can measure
We tie the work to numbers that matter to you and report against them honestly.
We stay after launch
Support and iteration are part of the relationship, not an upsell once real users arrive.
The stack
Technologies we use for this.
- React
- Next.js
- TypeScript
- Node.js
- PostgreSQL
- GraphQL
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
Common questions about web development.
How much does a custom web application cost?
It depends on scope, but we give you a fixed price in writing after a short discovery call, so there are no surprises. For a rough ballpark before we talk, try our free cost calculator. Work is billed in two-week increments you can see and steer.
How long until we have something usable?
You get a working demo at the end of every two-week sprint, and most web apps reach a usable first release within a couple of months, depending on scope. We build the core workflow first so value ships early rather than at the very end.
Do we own the code?
Yes, completely. You get the repository, the CI/CD pipeline and the documentation from day one. There is no lock-in and no proprietary layer you have to keep paying us for. You can take it anywhere.
Can you take over an existing app that has stalled?
Yes. We regularly pick up apps that have slowed down or lost their original team, stabilise them, and modernise in stages rather than attempting a risky big-bang rewrite.
