Web App Development Agency London

A website is usually focused on presenting and publishing information, while a web application allows users to perform tasks, work with data or interact with personalised functionality through a browser.

The line can overlap, but web apps typically include features such as accounts, permissions, dashboards, workflows, transactions, data processing, and integrations. If your requirement is primarily content and marketing, a conventional website or CMS may be the better solution.

That depends on how closely an existing product matches the way your organisation needs to work. Off-the-shelf software can be faster and more cost-effective when your requirements are standard. Bespoke development makes more sense when the process itself is distinctive, integrations are central or adapting an existing product would create ongoing limitations.

We assess the business case before recommending custom development. If established software already solves the problem well, there is little value in rebuilding it unnecessarily.

Timelines depend on the complexity of the product, integrations, design requirements and how much functionality is included in the first release. A focused MVP can move considerably faster than a large platform with multiple user types and interconnected systems.

We define the delivery approach during planning and, where appropriate, break larger products into phases so useful functionality can be released earlier rather than waiting for every future feature.

There is no single price for a bespoke web app because the scope can range from a focused MVP to a large, business-critical platform. Cost is shaped by the number and complexity of workflows, user roles, integrations, data requirements, UX and interface design, infrastructure and the level of testing required.

We start by defining what the application needs to achieve and which functionality creates the most value. You’ll then receive a clear proposal covering the agreed scope, approach and priorities. Where a phased release or MVP would reduce risk and get the product into users’ hands sooner, we’ll recommend it.

Yes. Bespoke web apps are often at their most valuable when they connect systems that would otherwise operate separately. We can integrate CRMs, payment gateways, ERP and stock systems, eCommerce platforms, marketing tools, external databases, AI services and other third-party platforms through APIs.

We map out how data needs to move between services, consider authentication and permissions, and design the integration so the application becomes part of your wider technology stack rather than another isolated tool.

We use cloud infrastructure suited to the application’s traffic, data, availability and scaling requirements. Depending on the product, that can include managed deployments, backups, monitoring, caching, queues and load balancing.

Hosting is considered as part of the application architecture from the beginning. We can also manage and support the environment after launch, giving the same development team visibility across the application and the infrastructure it depends on.

Yes. We work with clients in the UK and internationally, using video calls and collaborative project tools to keep planning, design, development and feedback moving wherever your team is based.

For UK clients, you can also meet us at our London studio at 107–111 Fleet Street, Ludgate House, London, EC4A 2AB, or with our team in Salisbury. We’re equally happy to run discovery sessions and project reviews remotely.
