Frequently asked questions
Your question is not listed? Drop us a line.
What separates a web app from a standard website?
A website primarily shares information. A web app provides interactive functionality: users log in, manage data, schedule bookings, or run custom workflows directly in the browser.
Do users need to install anything from an app store?
No. Web apps run directly inside any modern browser on mobile, tablet, and desktop. No installation required and zero app store fees.
How is pricing calculated for a web app?
After our first scoping session, we define the exact feature set and prepare a binding fixed-price proposal before work begins.
Which tech stack does Prephacy use for web apps?
We rely on clean, modern web standards including Astro, Next.js, TypeScript, and Supabase (PostgreSQL), avoiding brittle no-code workarounds.
