Frequently asked questions
How much does a custom web application cost?
It depends on scope, integrations and timeline. After a short discovery call we share a detailed, itemised estimate. For larger builds we recommend a fixed-price MVP phase so you can launch quickly, then expand.
How long does it take to build a web app?
A focused MVP typically takes 8 to 14 weeks, and a marketing website 3 to 6 weeks. You get a sprint-by-sprint plan before development starts.
Which framework will you use?
We choose the stack for your requirements, team and budget, most often React or Next.js with Node.js or Python, and explain the trade-offs in plain language.
Will my website be SEO friendly?
Yes. Semantic HTML, server-side rendering or static generation, structured data, sitemaps and Core Web Vitals optimisation are part of every build.
