Custom Web Applications

Web apps built around the way you actually work.

Polished, fast applications tailored to your workflow — from a single focused tool to a complex multi-role workspace. Designed in detail, engineered to last, accessible by default.

React / Next.js / SvelteKit / TypeScript / green Core Web Vitals

Real interfaces, in real hands.

01The idea

Off-the-shelf software bends your process to its shape. A custom application bends to yours.

That difference compounds. Every workaround you don't have to invent, every export to a spreadsheet you never make, every screen that does exactly one job well — it adds up to a team that moves faster and a product people are glad to open. We build the version of your software that fits like it was made for you, because it was.

02What we build

One craft, many shapes.

A web app can be a single screen or a sprawling workspace. The discipline is the same; the form follows your need.

Internal tools
01

Internal tools

The operational app your team lives in all day — fast, exact, and theirs.

Customer portals
02

Customer portals

A polished front door where clients see their data, files, and status.

Dashboards & analytics
03

Dashboards & analytics

The numbers that matter, legible at a glance and quick to drill into.

Workflow apps
04

Workflow apps

Reviews, approvals, and hand-offs modelled to how the work really flows.

Data & admin tools
05

Data & admin tools

Manage records, content, and settings without touching the database.

Client-facing products
06

Client-facing products

The thing you sell — designed to convert, built to scale with you.

03Tailored, not templated

The same building blocks. A result that's unmistakably yours.

Tailored interface design
Off-the-shelf & no-code

You adapt to the tool's idea of your business. The fields it allows, the roles it imagines, the limits it imposes. It's quick to start and slow to live with — and the day you need the thing it can't do, you're stuck exporting to a spreadsheet and paying per seat for the privilege.

Custom-built

The app adapts to you — the exact data, states, roles, and rules your work actually has. No per-seat tax, no ceiling you'll hit next quarter, no feature you have to fake. It costs more to make and far less to live with, and it keeps fitting as you grow.

04Built to feel fast

Speed isn't a setting. It's a budget we hold.

We design against a performance budget and measure it on real devices and real networks — not just a fast laptop on office wifi. The result is an app that responds the instant a person touches it, and keeps doing so as it fills with data.

Core Web Vitals, green — and kept that way with monitoring after launch.

Fast, responsive interface
05Accessible by default

WCAG 2.2 AA, from the first component.

Accessibility built in is invisible and effortless. Bolted on at the end, it's a scramble that never quite works. We choose the first — better for every user, and the right side of procurement and the law.

  • 01Operable with the keyboard alone, in a sensible order
  • 02Colour contrast that passes — every state, everywhere
  • 03Labelled and announced correctly for screen readers
  • 04Focus you can always see, never lost or trapped
  • 05Motion that respects a reduced-motion preference
  • 06Verified with real assistive technology, not just a linter
Design system
06A system, not just screens

The tenth screen in a fraction of the first.

We build a design system, not a pile of one-off pages — a shared set of components and tokens the whole app is made from. It's why the product stays consistent as it grows, ships faster the bigger it gets, and welcomes a new developer instead of confusing one.

  • Type, colour & spacing tokens
  • A real component library
  • Forms, tables & data views
  • States, empty & loading
  • Light/dark and density
  • Documented usage
07In motion

Software you want to reach for.

The proof of a good web app isn't a screenshot — it's the way it feels under your hands. Quick, certain, quiet.

08Under the hood

A polished surface needs solid foundations.

The parts no user sees are the parts that decide whether the app is a pleasure or a liability in a year.

  • 01

    Backend API & data model

    The logic and the data behind the interface, designed as one coherent system.

  • 02

    Auth & role-based permissions

    Who can see and do what — modelled correctly and enforced on the server.

  • 03

    Instrumentation from day one

    Analytics, logging, and error tracking wired in before launch, not after a fire.

  • 04

    Tests where they earn their keep

    Confidence to change things without breaking the things that matter.

  • 05

    CI/CD & previews

    Every change deploys to a preview you can click — and to production safely.

  • 06

    Documented for the next engineer

    So the app outlives the people who first wrote it.

09How we work

Working software early, and the whole way through.

01

Discovery

We learn the work — the people, the steps, the edge cases — and agree what the first version has to prove.

02

Design system & prototype

We design the components and a clickable prototype of the core flow, so the shape is right before we build it.

03

Build

Frontend, API, data, and auth, shipping to a live preview you use as it grows — short cycles, no big reveal.

04

Harden

We hold the performance budget green, pass the accessibility bar, and test the paths that matter.

05

Launch & hand over

We deploy, watch the numbers, and leave you with a documented, maintainable app your team owns.

10Right when

You know it's time.

  • You've outgrown a no-code tool

    It got you started and now it's in the way. Time for something shaped to you.

  • Your current app is slow or fragile

    Every change is scary and every page drags. A clean rebuild pays for itself.

  • No off-the-shelf product fits

    Your workflow is your edge — it deserves software that matches it exactly.

12Questions

The things teams ask us first.

The tool stops dictating your process. No-code platforms are wonderful until your workflow needs something the platform can't express — then you spend your days fighting its limits and exporting to spreadsheets. A custom app is shaped to the way your team actually works: the exact fields, states, roles, and rules you need, with no per-seat tax and no ceiling you'll hit again next quarter.

Let's build the app that fits.

Tell us about the workflow you want to make effortless — the tool you've outgrown, the app that's slowing you down, or the product you haven't built yet. We'll shape a custom web application around it.
