From our own work: We built Pulse, a fitness membership and coaching platform concept with member accounts, programs and a progress dashboard, to show how app products should look and behave. Read the Pulse case study.
When off-the-shelf software stops fitting
Spreadsheets, shared inboxes and five SaaS tools that don't talk to each other work until they don't. A custom web application replaces them with one system built around how your team actually works — customer portals, booking systems, dashboards and internal tools.
Engineered to last
We build with React, Next.js, Node.js and Python on PostgreSQL, with authentication, roles and audit logging designed in from the start. Every project ships with automated tests, documentation and deployment pipelines, so another developer could pick it up tomorrow.
What's included
- Product UX and interface design
- Full-stack development (React, Next.js, Node, Python)
- Authentication, roles and permissions
- Database architecture
- API design and third-party integrations
- Deployment, handover docs and full source code

Frequently asked questions
Do we own the software you build?
Yes. The code, repositories and cloud accounts are yours, with no licence fees.
Can you start with a smaller first version?
Yes. We usually scope a focused first release that solves the most expensive problem, then extend it in phases.
How much does it cost?
Every Custom Web Applications project is different, so we don't publish a price list. Answer a few questions in our quote builder and you'll get a personalised plan and estimate — compared with market prices and designed around your budget — in about 3 minutes.
Do I own what you build?
Yes. The code, content, accounts and data are yours. No lock-in — leave any time and we'll help you move.
