What we do
React development services
What we do with React, from a new app or a takeover to the APIs and support behind it.
Book a free React consultation
-
New web apps, portals and customer areas built in React, from the first screen to launch.
-
Tables, filters, charts and forms for the people who use and run your product every day.
-
API and backend integration
React front ends wired to your Laravel or Node.js backend and to outside APIs, with loading and error states.
-
UI component libraries
Reusable components built from your designs, so new screens look and behave the same way.
-
Moving to React
Old jQuery or server-rendered screens rebuilt in React one part at a time, while the current app stays live.
-
Fixes, library updates and new features after launch, tested on staging before they go live.
Choosing a framework
React, Vue or Angular?
We work with all three, so we have no reason to push you either way. This is how we help clients choose.
-
React fits when
- Your app is interactive: dashboards, catalogs, editors, live data
- You want the largest choice of libraries and developers who know it
- You may add a phone app later and want to share skills with React Native
-
Vue fits when
- Your team already runs Vue, often alongside Laravel
- You want templates close to plain HTML and a gentle learning curve
- You are adding interactive parts to an existing server-rendered site
-
Angular fits when
- A large team wants one framework with routing, forms and HTTP built in
- Your company already standardises on Angular and TypeScript
- You are building a long-lived internal app with many forms
-
When to add Next.js
Next.js is a framework on top of React. Add it when public pages must be found in search, load already rendered, or share one codebase with your marketing site. A dashboard behind a login usually needs React alone.
See our Next.js development → -
Need phone apps too?
React Native builds phone apps with the same way of thinking in components, so a React web app and its phone app can share a team and patterns.

How we work
From first call to a live React app
Six steps, and the same way of working on every project.
React development
What we build with React
The kinds of screens React is good at. Where a project in our case studies shows it, the card links to it.
-
Catalogs people browse
A streaming-style catalog where buyers browse every 3D property project, each keeping its own look.
Hauzd → -
Live data from APIs
Prices and availability come in through real-estate data APIs, so what buyers see updates without anyone retyping it.
Hauzd → -
Interactive media
Popups at a chosen point in a lesson video, notes in its corner, and a layout beside the video the school can change.
Xpectum → -
Data-heavy public sites
Weekly charts with movement, weeks on the list and peak on every row, plus search and downloads in four formats.
OLiS → -
Dashboards and admin panels
Tables, filters, charts and forms for the people who run your product, with roles so each person sees what they need.
-
Component libraries
Buttons, forms and layouts built once and documented, so your team adds new screens the same way.

Speed, security and care
Fast, safe and kept up to date
A React app is only as good as its first load and its next update. We look after both, before launch and after it.
-
Fast first loads
Code split by route, heavy parts loaded only when needed, and images sized for each screen.
-
Tested updates
React and library upgrades tried on staging first, then released once the checks pass.
-
Secrets kept safe
API keys stay on the server, input is checked on the backend, and access is kept tight.
-
Watched after launch
Errors reported as they happen, with fixes and new features once the app is live.
Cost
What does a React project cost?
Every app is different, so we quote after a short call, not from a price list. Within two working days you get an approach, a rough timeline and a rough cost range. No charge, no commitment.
What changes the price
-
Features
How many screens, user roles and features, and how interactive they are.
-
Design
Your own designs or a component library, or screens designed from scratch.
-
Integrations
Which services and data sources the app talks to, and how clean their data is.
-
The backend
Connecting to a backend you already run, or building one with the app.
-
Existing code
Starting fresh, or taking over and moving an existing app to React.
-
Aftercare
Monitoring, updates, fixes and new features once the app is live.
FAQ
React development questions
Straight answers, with the project behind each one where there is one.
How much does React development cost?
It depends on the screens and features, the design, the APIs and backend the app connects to, and whether you are starting fresh or moving existing code. We do not sell fixed packages. After a short call, we send an approach, a rough timeline and a rough cost range within two working days, with no charge and no commitment.
How long does it take to build a React app?
A focused app with a few screens on an existing API takes far less time than a full product with its own backend and many integrations. We give you a realistic timeline after the first call, and you see the work on a staging link every week.
What is React used for?
React is a JavaScript library for building user interfaces from components. It suits interactive web apps: dashboards, customer portals, catalogs, editors and screens that show live data. We used it for the catalog web app Hauzd buyers browse to find 3D property projects.
Should I use React, Vue or Angular?
We work with all three, so the answer depends on your app and your team. React suits interactive apps and has the largest choice of libraries; Vue suits teams already on Vue or Laravel and sites that need interactive parts; Angular suits large teams that want one framework with everything built in. For Xpectum's video tool, versions were built in both React and Vue.
Do I need Next.js, or is React enough?
React alone is usually enough for an app behind a login, such as a dashboard or an internal tool. Add Next.js when public pages need to be found in search, load already rendered, or share a codebase with your marketing site. We tell you which fits after the first call.
Can you take over or modernise an existing React app?
Yes. We read the code first, then fix what is unsafe, update React and its libraries on staging, and add features once the app is safe to change. Older jQuery or server-rendered screens can move to React one part at a time while the current app stays live.
Can you connect a React front end to our APIs and backend?
Yes. Our React front ends talk to Laravel and Node.js backends and to outside APIs. For Hauzd, prices and availability come in through real-estate data APIs; for OLiS, the platform pulls Spotify, YouTube and Apple Music data directly.
Who owns the code?
You do. The code goes into your own repository from the start, with hosting and domains in your company's name. When the work is done, you can keep us on or take it over, as OLiS's team did with documentation for setup, deployment and the API connections.
Do you work with companies outside India?
Yes. Our team is in Jaipur on IST, 4.5 to 5.5 hours ahead of London and 9.5 to 10.5 ahead of New York. The React projects on this page are for clients in Poland, the US and Sweden. Our UK company, Provis Global Ltd, is registered in the United Kingdom.
