Web Application Development

Most web apps do not fail because a feature was missing. They fail because the architecture stopped holding somewhere between the first hundred users and the first ten thousand. We build for the second number from the start.

What's included

How we help

Product web apps

Customer-facing applications where responsiveness and reliability are the product — dashboards, portals, booking flows, and multi-tenant platforms.

Internal tools and admin systems

The operations software your team lives in. Role-based access, audit trails, and interfaces designed around the actual workflow rather than the database schema.

API design and integration

REST and GraphQL APIs with real documentation and authentication, plus integration work against payment, CRM, and third-party systems you already depend on.

Legacy modernization

Incremental migration of applications that outgrew their original stack, without a rewrite-everything gamble that stalls the roadmap for a year.

How we work

Our approach

Discovery maps the real constraints — traffic patterns, integrations, compliance, and who maintains this after launch. Design validates the interface before production code exists. Build runs in agile sprints with weekly demos. Launch & Grow covers deployment, monitoring, and the iteration cycle after go-live.

In practice

What actually matters here

01

Choosing the architecture

The first real decision is rendering strategy, and it is usually made badly. A logged-in dashboard should be a single-page app; a marketing site or a catalogue that needs to rank should be server-rendered or static. Getting this wrong is expensive later — we rebuilt our own site for exactly this reason. We settle it in Discovery against how the application will actually be found and used, not by defaulting to whatever the team used last.

02

Designing for the second year

Most applications do not break under load. They break under change — when the fifth developer joins, when a feature cuts across three modules that assumed they were independent, when a schema decision made for the first release blocks the tenth. We keep boundaries explicit, migrations reversible, and the data model shaped around access patterns rather than the first screen that needed it.

03

Integrations are someone else's uptime

Every third-party system you depend on is an API you do not control, with rate limits, breaking changes, and outages on someone else's schedule. We put integrations behind a boundary in our own code, so a provider changing its response shape is a contained fix rather than a rewrite, and an outage degrades one feature instead of the whole application.

04

Handing it over properly

A project is not finished when it deploys. We hand over documented environments, reproducible infrastructure, a deployment path your team can run, and monitoring that pages on real problems. If you have an in-house team, we work so they can take it forward without us. That is the intended outcome, not a fallback.

Web Development FAQ

Common questions

How much does a custom web application cost?

It depends mainly on the number of distinct user roles, how many systems you integrate with, and whether compliance requirements apply — a focused internal tool and a multi-tenant customer-facing platform are very different projects. We scope properly before quoting rather than publishing a figure that would be wrong for most people. Get in touch and we will give you a real range in the first conversation.

How long does it take to build a web application?

A focused application typically ships in 8–12 weeks from kickoff. Larger platforms with multiple user types and heavy integrations run 4–6 months. The timeline comes out of Discovery once scope is fixed, and we plan in sprints with weekly demos so progress is visible throughout.

Should we build a single-page app or a server-rendered site?

It depends on whether the content needs to be found by search engines. Anything behind a login is a fine candidate for a SPA. Anything public that should rank — marketing pages, catalogues, listings — should be server-rendered or static, because search and AI crawlers see the initial HTML response. Many products correctly use both.

Can you work with our existing codebase?

Yes. We regularly extend existing applications, take over from a previous agency, or embed alongside an in-house team. Discovery includes auditing what is already there before we change anything, so the plan accounts for the code as it is rather than as we would have written it.

Who owns the code?

You do. Source code, infrastructure configuration and documentation are yours, in your repositories and your cloud accounts wherever possible. We are not interested in engagements that depend on holding your code hostage.
