FAQ
Frequently Asked Questions
What is the difference between a website and a web application?
A website primarily presents information (brochure site, blog, portfolio). A web application is interactive software that runs in a browser, users log in, enter data, and the system responds dynamically. Examples include customer portals, booking systems, inventory management tools, and SaaS products. We build both, often combining them.
What tech stack do you use for web applications?
We primarily build with Next.js (React) on the frontend and Node.js, Python (FastAPI/Django), or Go on the backend. For databases we use PostgreSQL, MongoDB, and Redis. We choose the stack that best fits your requirements, team capabilities, and long-term maintenance needs, not just what we prefer to code in.
How do you handle security in web applications?
Security is built in from day one: OWASP Top 10 compliance, parameterised queries to prevent SQL injection, CSRF protection, rate limiting, input validation, Content Security Policy headers, and regular dependency auditing. We are ISO 27001 certified and can work to specific security requirements for regulated industries.
Can you build a web application that works offline?
Yes. Progressive Web Apps (PWAs) can cache data locally and continue working without an internet connection, syncing when connectivity is restored. This is common for field service applications, inspection tools, and apps used in warehouses or remote locations.
How do you price web application development?
We price based on scope: complexity of features, number of integrations, user roles, data volume, and performance requirements. Most web applications fall in the £20,000–£150,000 range. We work in fixed-price sprints so you always know what you are getting and what it costs.
