Web Application Development Services
Web application development is building software that runs in the browser, such as dashboards, booking systems, portals and marketplaces. Nexdevix builds web apps with React, Next.js and Node.js that load fast, rank in search where needed, and scale from the first hundred users to the first hundred thousand.

Performance and SEO rebuilds
Move slow sites to a modern stack with better Core Web Vitals.
Web apps that are fast, secure and easy to change
A web application is only useful if people enjoy using it and your team can keep improving it. We focus on three things: page speed, clean architecture and automated testing, so the app stays quick and changes stay cheap as it grows.
Our default web stack
- Front end: React and Next.js for interactive interfaces that can also be server-rendered for SEO.
- Back end: Node.js and Express APIs with MongoDB, all in TypeScript.
- Hosting: Vercel or Cloudflare with automatic deploys and preview links.
From first version to scale
Most clients start with a focused first release, measure how people use it, then add features in priorities you set. If you are still validating the idea, start with an MVP. If you plan to charge subscriptions, see SaaS development.

FAQ
Web App Development FAQs
Which framework do you use for web apps?
Our default is React with Next.js on the front end and Node.js with Express and MongoDB on the back end, all in TypeScript. We choose based on your team, hosting and hiring plans, and explain the trade-offs before we start.
How much does a web application cost?
Most web apps we build cost between $12,000 and $120,000, depending on the number of features, roles and integrations. A focused first version is often under $30,000.
Can a web app work on mobile?
Yes. Every web app we build is responsive, and we can make it a progressive web app that users install on their phone's home screen.
Do you host the application?
We set up hosting on your own Vercel or Cloudflare account, so you keep control and pay the provider directly.
