When a web app is the right call

We are an app studio, and we will tell you honestly when your product belongs in someone\'s pocket as a mobile app. But a web app — built in React and Next.js — is often the smarter first move. We recommend going web when:

Your users are on desktop. Dashboards, admin panels, and B2B SaaS where people work on a laptop are a natural fit for the web.
You need to be found on Google. Content- and marketing-driven products live or die by search, and a Next.js web app can actually rank.

You want to validate fast. Ship to a URL today, with no app-store review, and iterate the same day you have feedback.
Reach without install friction. Anyone with a link can use it — no download, no store account, works on every device.

And here is when we will steer you to mobile instead: if your value depends on push notifications, the camera, offline-first behaviour, or being in the App Store and Google Play, you want a real mobile app — see our iOS, Android, and Flutter work. Plenty of products are both: a web app plus a mobile companion sharing one backend, which our full-stack team builds together.

What we build with React & Next.js

We build production web apps in modern React — Next.js for routing and server rendering, TypeScript for a codebase that holds up, and a clean component architecture you can hand to any React developer later. The products we ship most often:

SaaS dashboards & admin

Data-dense dashboards, admin panels, and back-offices with roles, billing, and real-time updates.

Customer & client portals

Secure portals where your customers or clients log in to manage accounts, orders, and documents.

Installable PWAs

App-like Progressive Web Apps that install to the home screen, work offline, and send web push.

The stack we reach for: React and Next.js, TypeScript, Tailwind CSS, a Node.js or Laravel API, Postgres or MySQL, Stripe for billing, and authentication done properly — deployed on Vercel or your own cloud. When the web app needs a shared backend or a mobile companion, our full-stack team builds the whole thing as one system.

Web apps that load fast and get found

A lot of web apps are a blank page until the JavaScript loads — slow for users and invisible to search engines and AI assistants. We build the opposite:

Server-rendered for SEO. Next.js renders the pages that need to rank on the server, so Google and AI search read real content, not an empty shell.
Built for Core Web Vitals. Fast loads, stable layout, and snappy interaction — the speed signals that affect both ranking and conversion.

Installable & offline-capable. PWA support so users can add the app to their home screen and keep working without a connection.
Responsive everywhere. One app that works on a 27-inch monitor and a phone browser, without a separate mobile site.

What is included in every web build

Discovery Sprint. We scope the app, design a clickable Figma prototype, and hand you a fixed-bid statement of work before any code is written.
Product & UX design. Interfaces designed for real workflows, not just screens that look nice in a deck.
React & Next.js development. Built in weekly milestones with a live preview URL you can click through any time.

Backend & APIs. Auth, payments, notifications, and an admin layer, built to share data cleanly with any future mobile app.
Deployment & launch. Hosting on Vercel or your cloud, domains, and SSL — and because there is no app store, you ship the day it is ready.
Post-launch support. Dependency updates, bug fixes, and performance and uptime monitoring after you go live.

What we don\'t build

We say no to work we are not the right team for, on the first call — never after taking your money. We don\'t build games, HIPAA-regulated clinical systems, blockchain or Web3 products, or heavy machine-learning platforms. If that is your project, we will tell you up front and point you toward a team that is a better fit.

FAQ’s

Web App Development FAQs

This page is about React.js and Next.js web apps — software that runs in the browser at your own URL. That is different from React Native, which we use to build native mobile apps for the App Store and Google Play. If you need a phone app, see our React Native or Flutter pages; if you need a web app, dashboard, or portal, you are in the right place.

It depends on where your users are and what they need. If your users are on desktop, your product is dashboard- or content-heavy, or you need to be found on Google, a web app is usually right. If your value lives in someone's pocket — push notifications, camera, offline-first, app-store presence — you want a mobile app. Many products are both: a web app plus a mobile companion sharing one backend. We help you decide on the Discovery Sprint.

Our fixed-bid tiers run from a $7,997 Starter build to a $59,997 Scale build, with most funded-startup web apps landing in the $14,997 to $29,997 range. We start with a $1,997 Discovery Sprint that scopes the app, delivers a clickable Figma prototype, and gives you a fixed bid before you commit.

Most web-app MVPs ship in about six weeks from the end of the Discovery Sprint. Larger products with custom backends, billing, and multiple roles take eight to twelve weeks. Because there is no app-store review, we can deploy updates the same day they are ready.

Yes. We build PWAs that users can install to their home screen, that work offline for the parts that make sense, and that receive web push — all without an app store. It is often the fastest way to get an app-like experience in front of users on every device.

It can, and that is a real advantage of building on Next.js. We server-render the pages that need to be found, so search engines and AI assistants read your content instead of a blank JavaScript shell. We build for Core Web Vitals and clean, crawlable markup from the start — the same discipline behind this site.
