FAQ

How much does a web app cost in 2026?

A simple MVP starts at €3,000–€8,000. A full SaaS platform with auth, billing, and admin typically runs €15,000–€40,000. Enterprise projects with complex integrations can exceed €100,000.

How long does it take to build a web app?

MVPs ship in 2–6 weeks. Production-ready SaaS platforms take 6–12 weeks. The biggest variable is feature scope, not the agency itself.

Should I hire an agency or freelancers?

Agencies offer project management, design, QA, and devops as a package. Freelancers are cheaper but require you to manage coordination. For first-time founders, agencies reduce risk.

What tech stack should I choose?

For most startups in 2026: React + Next.js frontend, Firebase or Supabase backend, Stripe for billing. This stack has the largest talent pool and fastest development speed.
