Criteria to consider when evaluating a React.js company

There is a vast market of React.js development companies. It’s vital to choose the best firm so you don’t waste your time and money. If you don’t know how to hire a skilled React.js developer, check out our criteria.

React.js companies choice criteria

Company’s reputation

There are many sites where clients can share honest feedback about companies. Don’t hesitate to explore these sites, and check out a company’s rating on Clutch, one of the most popular feedback platforms. 

However, there are plenty of other reliable platforms that score web app development platforms, including:

Read reviews submitted by real people. They can be full of helpful insights about the development workflow and other aspects of a company. 

It's vital to become a meticulous reviewer. For starters, pay close attention to a firm’s main focus. Some firms prefer working with small startups, while others prefer enterprises. 

Most review sites publish detailed ratings with various criteria. Here are the ones you should focus on to find a top-tier firm:

  • Quality. This criterion describes a product’s or service’s quality. Pay close attention to the quality rating because it evaluates a company’s professional approach and expertise. 
  • Scheduling. This criterion describes the company’s ability to deliver products on time and to meet scheduling deadlines. Searching for a high scheduling score will help you find a dependable firm.
  • Cost. This factor describes the affordability of a company's services. The cost rating can help you understand if other people find the price of the services reasonable.

Many top React.js development companies deliver outstanding quality products. Unfortunately, it’s a challenging task to find a firm that provides affordable and top-tier products quickly. Try to find the optimal balance between price, quality, and speed.

Cheap, fast, good rule

If you run a startup, there are many other factors that may affect your decision to hire a React.js development company. Let’s examine the most important criteria to consider.

Clearly defined workflow

When exploring React.js agencies, take a close look at their workflow. The React.js web application development workflow should have specific well-defined steps. Having well-polished and outlined software development processes allows a company to build high-quality products faster than its counterparts.

Pre-made components and design systems

While the React.js library offers access to ready-to-use components, standardized style guides and pre-made components help make the web application development process consistent. Software engineers should follow reliable instructions and use pre-built items.

We recommend checking if a firm has pre-made components and a pre-made design system. They help agencies deliver top-quality products fast, save money, reduce stress, and make it easy to scale existing products.

Company’s portfolio 

A company’s website can be a source of helpful information. It’s always a good idea to inspect a company’s completed projects to learn about the company’s abilities to fulfill your needs. Most companies share case studies to show potential clients their React frontend development qualifications. 

Browse case studies to learn more about the complexity of firms' projects and engineering solutions. Look for projects similar to yours, and evaluate them. This will help you understand if a company can fulfill your React.js needs.

Social involvement

Social media is a powerful instrument that helps companies stay in touch with their clients. Also, social media can help you assess a company's React.js expertise. Check if a company publishes content about technologies, design, or business. If a company shares its expertise in different niches online, it likely has a team of skilled professionals who can build top-tier products. 

However, if most of a company’s social media publications are about popular subjects, that's a red flag. It can signify that a company lacks specialists to share expert content. Don’t hesitate to check if a company publishes professional articles on their website or on social media. 

Open source software development

We recommend analyzing a company’s commitment to the React.js community. Niche-leading companies constantly contribute to the industry by sharing open source projects.

If a company creates and shares open source software for free, they can showcase its technology expertise while helping the community develop. One popular way to examine a company’s commitment to the community is to check their GitHub profile.
