What is custom web application development?

It is building browser-based software around your own process instead of adapting your process to a packaged product. Examples are customer portals, booking and approval systems, internal dashboards and SaaS products. A custom build covers the interface, APIs, database, user roles, integrations and hosting, and the finished code belongs to you so it can be extended later.

How much does it cost to build a custom web application?

The price depends on the number of user roles and screens, the integrations, data migration and how much design work is needed. For a defined first release we quote a fixed price after discovery, split into milestones. For products with a changing roadmap we propose a dedicated team at a monthly fee. Send us your requirements and we reply within one business day.

How long does it take to build a web application?

It depends on scope, and we give a timeline in the proposal rather than a guess on the first call. We work in two-week increments, so you see working screens on staging early. A focused first release with the essential workflows is usually the fastest route, with further features added once real users have tried it.

Should we build custom or buy an off-the-shelf tool?

Buy when a packaged product covers your process with only configuration and the licence cost stays reasonable as you grow. Build when the workflow is what sets your business apart, when you need several tools to talk to one data model, or when per-user fees grow faster than the value. We will tell you if buying is the better option.

Which technology stack will you use?

Usually Angular, React or Next.js for the interface, FastAPI, Django or Node.js for the backend, and PostgreSQL or MongoDB for data, all in TypeScript or Python. We pick based on what your team can maintain, what already exists and what the application needs, and we explain the choice in writing in the proposal.

Who owns the source code and the hosting?

You do. The repositories live in your GitHub, GitLab or Azure DevOps organisation, and the application runs in your AWS, Azure or server accounts from the start. Documentation and runbooks are stored with the code. If you later move development in-house or to another supplier, there is nothing to transfer back from us.

Can you take over or rebuild an existing web application?

Yes. We start with a review of the code, database and hosting, then recommend whether to stabilise and extend it, rebuild it module by module alongside the old system, or replace it. Gradual replacement keeps the business running, and data migration is planned and tested on staging before cut-over.

What happens after the application goes live?

On a support retainer we handle bug fixes, dependency and security updates, backups, monitoring and small features, with response times agreed in the retainer. If you prefer to run it yourselves, we hand over the code, runbooks and an admin guide, and run a session with your team so they can deploy and maintain it.
