A QUICK SUMMARY – FOR THE BUSY ONES
TABLE OF CONTENTS
These are the top 20 React development companies in the world. Plus, fun fact, no one paid us to be included here, there are no marketing agreements. They simply proven best based on the research and analysis.
Choose the top provider of React development services for your specific case by analyzing the diagrams below and reading detailed descriptions of companies.
Let’s start with the comparison of three basic characteristics of each company: years on the market, team size, and tech stack. Each one is carefully explained, so you can assess what kind of company will be good for you, and easily compare the ones that meet your requirements next to each other, on a graph.
Is an older company always a better choice?
Companies that operate for some time now, have most likely achieved high maturity in their processes. Age translates into their experience, and they probably have high expertise with a few chosen industries.
On the other hand, a company grows over time. The more leaders, the more decision-makers, and, as a consequence, more bureaucracy, and stiff procedures. However, it all depends on the company’s culture, so you may want to check if the vendor seems like a fit.
What about younger companies?
Younger companies often have a fresh look at things, are less opinionated, and have more flexible procedures. They can also have senior engineers on board.
However, in terms of a young company, experience is something you definitely need to check. Do it by looking through their portfolio and talking to previous clients. (Companies from this toplist have documented experience in various projects and industries.)
We’ve already lifted the veil of secrecy in the previous section, but a few more important details are needed.
A big company may be a good choice when you need a lot of developers for your project. So your demand is one thing. The second is, how quickly you need them - because you won’t necessarily get them as fast as you’d like.
You shouldn’t identify the high number of developers with the fact that a company can start the cooperation quickly. To be able to do that, a company needs to purposely manage its people and resources to maintain a sufficient buffer.
Plus, as we’ve said before, in the case of big companies, there are often many formalities to go through before the project can start. That slows down the start.
Is choosing a smaller company a more viable option then? When your demand isn't very high, then most likely yes.
Most often a small company will speed up the formalities.
Plus, small players are also more flexible and able to approach the partnership in a more personalized way, especially when it comes to building a team.
Last but not least, it’s no secret that small companies often care more because they want to prove their abilities and expertise.
Here we don’t assess the specific technologies, but their range in a tech stack.
Why?
If you’re not sure which technology will be best for your product, only assume React, or have no idea for the backend, a company with a broad tech stack may have a lot of expertise and help you choose.
However, in our opinion, when you’re an expert at everything, you’re actually an expert at nothing.
A very broad tech stack may be justified in the case of a big company, with hundreds of developers on board.
Smaller companies with a narrower tech stack are more likely to actually be experts in their fields. Plus, top vendors won’t persuade you to develop a product in their technologies of expertise if it won’t fit. So if React is not the right choice for you, they will tell you.
What exactly do we mean by approach?
It’s a way a company engages in cooperation. It’s how they perceive their clients, how they deliver business value and value in general.
We assess 6 aspects here:
As it was before, details are below. Each section has a description to help you grasp crucial aspects and make a conscious decision.
How did we assess that?
A company’s approach is visible:
Remember: we have great players here. The fact that the company is more to the left, doesn’t mean they don’t provide anything at all. It just means someone puts more attention to that.
And the final question will be which aspects are most important to you.
The goal here is to deliver the best business results possible. The bigger attention a company pays to achieving your business goals and not just delivering a set of features, the better chance for that success to happen.
How does it manifest?
Consultancy attitude is all about sharing knowledge. It can be consulting as a service, but even better if a team shares knowledge with yours simply while collaborating.
It brings great value when a vendor's team mentors and supports your developers. It may concern technical knowledge, but also project management or design.
That’s not a typical approach to outsourcing.
You may associate DevOps with Cloud and CI/CD, but that’s only one side of it. Here we assess the DevOps culture, which presupposes tearing down the boundaries between developers and operations. No boundaries mean close cooperation and an undisturbed flow of knowledge.
That kind of attitude increases transparency, improves communication, and leads to more flawless collaboration. The team is happier and more productive, which leads to a better product.
With time to impact we try to assess how fast a company can make an actual influence on your product or service.
Tech advisors in a team or offering workshops help to start the cooperation quickly and make an impact right away.
Time to impact is highly influenced by the company’s processes:
When we talk about ownership, responsibility is one thing, and the other is accepting the possibility of making mistakes and knowing how to deal with them.
The team with a high sense of ownership works more transparently and takes better care of communication. They have nothing to hide because they own their mistakes.
Ownership can also manifest in a team being able to work independently, not babysitted by a client.
Seems like the ability to make decisions and high transparency is the needed mix here.
The partnership means sinking into your team and working towards your business success with high engagement. It means a friendly, but professional relationship.
The vendor’s team is professional and fun to work with at the same time. They are committed, dedicated, and proactive.
There’s nothing to think about here - the more engaged the team is, the better. Unless you want to work quietly and independently - that’s closer to traditional outsourcing, but in this toplist we included companies that prefer different types of collaboration.
Time for a set of information about each company.
Check the scope of services offered by each vendor, read more about their skills and what kinds of talents they have on board, get familiar with their culture and aspects clients appreciate in their work.
