FAQ
Questions about web development.
How much does a web app cost?
A web MVP usually costs $25,000–$60,000; SaaS platforms are built in phases. You get a detailed estimate after a free call.
Which stack do you recommend?
Usually React or Next.js with Node.js or Python, PostgreSQL and AWS — proven, fast and easy to hire for.
Can you take over an existing project?
Yes. We start with a code audit, fix the critical issues and then continue development.
Do you build the admin panel too?
Yes — admin panels, reports and roles are part of most projects we deliver.
Will it work on mobile?
Every web app we build is responsive, and we can turn it into a PWA or add native apps later.
What is custom web application development?
Custom web application development means building a web product around your users and processes — for example a SaaS platform, customer portal or dashboard — instead of adapting a ready-made template or CMS.
Why choose Perpetio for web development?
Perpetio builds web apps on a proven stack — React, Next.js, Node.js, PostgreSQL and AWS — with a demo every two weeks, automated testing and full code ownership for you.
