Note (September 2026): This guide has been corrected: ReactJS (React) is a JavaScript library for building user interfaces, mainly on the web; native Android and iOS apps are built with its sister framework, React Native. The conclusion also mentioned only offshore companies in India, although the advice applies to any React development company.
To choose the right ReactJS app development company, confirm whether you need React (web interfaces) or React Native (native mobile apps), then check the company’s shipped React projects, its use of current tooling such as React 19 and a framework like Next.js or Expo, its code-review and testing practices, clear communication, and a contract that gives you the source code and intellectual property.
Key Takeaways
- React (also called ReactJS or React.js) is an open-source JavaScript library for user interfaces; React Native uses the same model to build native Android and iOS apps.
- As of September 2026 the latest React release is 19.3.0 (September 9, 2026) and the latest React Native version is 0.87, according to the official React and React Native documentation.
- Create React App was deprecated for new apps on February 14, 2025; a company still starting new projects with it is not following the official recommendations.
- Ask for live projects, code samples, a named team, a testing process and a written statement that you own the code.
- Start with a small paid discovery phase or pilot before committing to a full build.
Hiring one of the best ReactJS development company is similar to hiring any other professional service who you want to help you with the growth of your business. It is not only about the best ReactJS development company but also one that fits your project’s requirements, budget and timeline.

The popularity of React (ReactJS) for web interfaces, and of its sister framework React Native for mobile apps has increased demand for React app development services. Strictly speaking, ReactJS is a JavaScript library for building user interfaces, while native Android and iOS apps are built with React Native, so first decide which one your project needs.
And if you think that finding the right development company or developer is an easy task, then think again. You can’t hire just anyone to build apps for you. The market reputation of the company and how successfully it helps businesses scale their growth with the right mobile apps are things that also matter a lot.
This is an investment that you need to give ample time for it to pay dividends. There is a lot that you need to look into when it comes to the company that you are going to work with before you make the final call of hiring them.
What to look for in a ReactJS app development company?
Does the app development company have the desired domain expertise? There are so many technology frameworks available out there for building mobile apps. But few app development companies have genuine experts in every one of those technologies, so check that the company has shipped real projects with React (for the web) or React Native (for mobile).
Finding a company that comes with expertise in multiple domains is a good way to start. Look for companies that employ full stack developers. These developers are skilled enough to utilize different technologies for building mobile apps. But make sure that the company you choose delivers quality work.
Is the app development company flexible enough? Is it open enough to accommodate different needs? You should look for a company that doesn’t mind taking inputs and incorporating them in the middle of the project.
If the development company is flexible, you won’t have any problems in working with them. Also, ask them whether or not they charge for incorporating inputs during the project. It is always better to clear all the doubts right at the start.
There is no alternative to experience. Make sure that the company that you are going to work with employs experienced ReactJS developers, and ask which of them will actually work on your project.
You need to understand that developers that are new to the industry and are not aware of how things work here are more likely to make mistakes that can be detrimental for your project. Make sure you interview developers and check for yourself if they are good enough for the job.
Ask them about the different projects that they successfully completed over the years. Make sure you have all the details of those projects. This will help you understand the way that the company approaches different projects. This will help you in setting your expectations right.
It is also important that you work with a company that follows clean coding standards. The coding standard ensures that developers working on a particular project follow specific guidelines while creating and working on the code.
This helps all the developers to maintain code consistency. If developers follow clean coding standards, it is easier for making changes to the code later.
Does your app development company keep its developers up-to-date with the latest technology trends? Does it organize sessions to learn new concepts?
If it does all this, its developers would be better equipped to innovate for different projects. They will be able to smartly handle challenges and make the most of the resources and tools available to them.
The development methodology that a company follows directly impacts the outcome of the project. The first step should always be a discovery phase in which the company gathers your requirements, target users and success criteria.
If the company hasn’t really bothered discussing any details with you after you outsourced the project to them, it indicates that they aren’t going to listen to you too much during the project.
For a project to be successful, proper communication between the two parties is very important. Make sure they listen to you and suggest things depending on their experience. If there is any gap in communication, the project will not reach its desired end.
Conclusion
These are some of the important things to keep in mind when choosing a ReactJS app development company, whether it is local, remote or offshore (for example, in India). Check its React experience, tooling, process and contract terms, and start with a small pilot before committing to the full project.
ReactJS vs React Native: Which Does Your Project Need?
React is a free and open-source front-end JavaScript library for building user interfaces from reusable components. React was created by Jordan Walke at Facebook, first used on Facebook’s News Feed in 2011 and open-sourced in May 2013. React Native, announced in February 2015 and open-sourced in March 2015, applies the same component model to native apps for Android, iOS and other platforms.
In October 2025 Meta announced that it would donate React, React Native and JSX to a new React Foundation, part of the Linux Foundation, so the technology is no longer governed by a single company.
| Question | React (ReactJS) | React Native |
|---|---|---|
| What it builds | Web user interfaces: single-page apps, websites, dashboards, server-rendered apps | Native apps for Android and iOS, plus other platforms such as Windows and macOS |
| Renders to | The browser DOM | Native platform views (no HTML or CSS) |
| Officially recommended starting point | A framework such as Next.js or React Router | A framework such as Expo |
| Latest version (September 2026) | 19.3.0, released September 9, 2026 | 0.87 |
| Skills to look for | JavaScript or TypeScript, React hooks, a React framework, web performance and SEO | JavaScript or TypeScript, React, native build tools (Android Studio, Xcode), app store publishing |
If you need both a website and mobile apps, ask whether the company can share code and design components between its React and React Native teams.
How Popular Is React?
React is one of the most widely used web technologies. According to the 2025 Stack Overflow Developer Survey, 44.7% of all respondents (46.9% of professional developers) said they had worked with React in the past year, second only to Node.js among web frameworks and technologies. That popularity makes React developers comparatively easy to find, but it also means a large pool of companies with very different levels of skill.
Is the Company Using Current React Tooling?
A good React company follows the official recommendations rather than setups that have been retired. As of September 2026, the React documentation recommends starting a new app with a framework. It names Next.js (App Router), maintained by Vercel, and React Router (v7), maintained by Shopify, for web apps, and Expo for native apps.
The React team deprecated Create React App for new apps on February 14, 2025, citing that it had no active maintainers, and advised existing apps to move to a framework or to a build tool such as Vite, Parcel or Rsbuild. Other current topics to ask about include:
- Function components and Hooks: React has recommended function components since version 16.8 (February 2019); new code written mainly as class components is a warning sign.
- Server Components: React Server Components became stable in React 19 and are most readily used through Next.js.
- React Compiler: the React team has released React Compiler 1.0, which optimizes components automatically; ask whether the company has evaluated it.
- TypeScript: TypeScript is often used over JavaScript in modern React Native apps for its type safety, and many web teams use it as well.
Step-by-Step: How to Hire a ReactJS Development Company
- Write a short brief. Describe the problem, target users, must-have features, platforms (web, Android, iOS), deadline and budget range.
- Build a shortlist of three to five companies. Prefer companies with live React or React Native products you can open and use yourself.
- Check their work. Ask for two or three case studies similar to your project, and ask to speak with past clients.
- Run a technical interview. Meet the developers who would work on your project, not only the sales team, and ask them to explain one of their past architectural decisions.
- Review a code sample. If you are not technical, ask an independent developer to review it for structure, tests and readability.
- Compare proposals. Look at scope, milestones, team size, assumptions and what is excluded, not just the total price.
- Agree on the contract. Confirm who owns the code and intellectual property, where the source code lives, the warranty or bug-fix period, and how change requests are priced.
- Start with a pilot. A paid discovery phase or a small first milestone shows how the team communicates before you commit to the full build.
Questions to Ask a ReactJS Development Company
- Which React or React Native apps have you shipped that are live today?
- Which framework and React version would you use for this project, and why?
- How do you handle state management, routing and data fetching?
- What automated tests do you write, and how is code reviewed before it is merged?
- How do you measure and improve performance and accessibility?
- Will we have access to the code repository, task tracker and staging builds from day one?
- Who will be our day-to-day contact, and how often will we have progress calls?
- What happens after launch: maintenance, updates for new React versions and app store changes?
Common Engagement Models Compared
| Model | How you pay | Best for | Main risk |
|---|---|---|---|
| Fixed price | An agreed total for an agreed scope | Small, well-defined projects | Every change request costs extra; scope disputes |
| Time and materials | Hours or days actually worked, at agreed rates | Projects whose requirements will change | The total cost is less predictable |
| Dedicated team | A monthly fee for developers working only on your product | Long-term products with continuous development | You must manage priorities closely |
Rates vary widely by country, seniority and project size, so compare several written quotes for the same brief rather than relying on published averages.
Red Flags to Watch For
- No live React or React Native projects you can check yourself.
- A quote given before anyone has asked about your users, features or deadline.
- Refusal to let you meet the developers or see any code.
- New projects still started with Create React App or written mainly with class components.
- No written answer on who owns the source code and intellectual property.
- No testing, code review or staging environment in the proposal.

Frequently Asked Questions
Is ReactJS the same as React?
Yes. ReactJS, React.js and React are names for the same open-source JavaScript library for building user interfaces. It is now governed by the React Foundation, part of the Linux Foundation, after Meta announced the donation in October 2025.
Can ReactJS be used to build mobile apps?
React itself renders web interfaces, which can run in a mobile browser. Native Android and iOS apps are built with React Native, which uses the same component model; the React Native documentation recommends starting with a framework such as Expo.
What is the latest version of React?
As of September 2026 the latest React version is 19.3.0, released on September 9, 2026, according to the official React versions page. The latest React Native version is 0.87.
Should a React company still use Create React App?
No, not for new apps. The React team deprecated Create React App on February 14, 2025 and recommends a framework such as Next.js or React Router, or a build tool such as Vite, Parcel or Rsbuild.
How do I check a React developer’s skills if I am not technical?
Ask for live projects you can use, speak with past clients, and pay an independent developer to review a code sample and join the technical interview. A short paid pilot also shows the quality of the work before a larger commitment.
Who should own the code of my React app?
You should, in most cases. Make sure the contract states that the source code and intellectual property transfer to you, and that you have access to the code repository throughout the project.
