Custom Web Applications
Custom web application development
When a website is not enough, you need a web app - a CRM, a client or patient portal, a dashboard, or a booking system. Studio N builds custom web applications end-to-end, led by a senior full-stack developer with 13+ years of experience. No outsourcing.
Why a web app
A website shows information. A web application does the work.
Manual work that should be automated
If your team copies data between spreadsheets, chats, and email, a custom app turns that into one system that does it for you.
Off-the-shelf tools don't fit
Generic SaaS forces your process into its boxes. A custom web app fits your exact workflow, roles, and data.
You need accounts, roles, and data
Logins, dashboards, permissions, payments, integrations - these need an application, not a static site.

FAQ
Custom web app development - questions
What is the difference between a website and a web application?
A website mostly presents information. A web application lets users do things - log in, manage data, book, pay, and see dashboards. Studio N builds both, including custom web apps with user accounts, business logic, and APIs.
How much does a custom web app cost?
Custom web applications start from $5,000. The final price depends on features, user roles, integrations, and complexity. We give a fixed quote after a free consultation call.
Do you build CRMs and client portals?
Yes. We build CRMs, client and patient portals, admin dashboards, booking systems, and internal tools with role-based access, integrations, and APIs.
What technologies do you use for web apps?
React, Vue.js, Angular and Ionic on the front end; Node.js, Express, Fastify, PHP and Laravel on the back end; with MongoDB, PostgreSQL and Redis databases and REST APIs.
