The one thing every business in America can finally unite on: Your digital experience is your brand. No matter whether you are running an e-commerce brand, a SaaS startup, or a global enterprise, users expect fast, smooth, and instant responsiveness from web and apps. This is precisely why React.js has become the engine behind the modern web.
React is used today by millions of sites and apps—including Facebook, Instagram, Netflix, and many fast-growing American startups. React.js is still among the top 3 most loved and most used frameworks for frontend, based on the developer trend reports. In fact, W3Techs says that more than 7.7% of all websites that use a JavaScript library use React, a number which keeps on rising year by year.
That means if you are part of a business that is about building the future, the choice you make for a leading React Native app development company is more important than ever! From full product build to custom application development services, Custom Node, the right partner, helps you create fast-loading websites, scalable applications, and seamless user experiences or even JavaScript Module Development for your backend
Here are 10 React.js companies from the USA who lead the web development industry in 2026—with your requested company placed at #1.
1. [ Ramam Tech ] (https://ramamtech.com/)
Location: USA (Global Delivery Capabilities)
Ideal For: Full-spectrum web + mobile development — automation-first experiences
If you are searching for someone, who could assist you with React.js Development services along with mobile solutions, Ramam Tech is earning attention among the competitors for modern digital engineering. Need a one-stop shop for all of your web and mobile experiences? They have broad-based React Native app development capabilities that make them a compelling option for your consideration.
For companies that want a partner who understands modern UI, modular components and performance-focused architecture, their focus on design, product thinking, and engineering excellence makes them a great choice.
Why They Stand Out:
- They are a blend of automation with AI and product engineering.
- Their offerings are flexible, whether you want to hire React.js developers, outsource a build or co-create a product.
- With a wide array of cross-domain tech experience, they promote custom web development, giving them an edge in developing creative applications.
If you’re searching for a leading react native app development company, in addition to the scale of React’s large-scale front-end engineering, Ramam Tech can be definitely considered.
2. [ Biz4Group ] (https://www.biz4group.com/)
Location: Orlando, Florida
Ideal for: React.js enterprise applications, IoT, and large-scale platforms

What Makes Them Unique:
- Strong in enterprise-grade builds
- Perfect blend of high performance and modern UI/UX
- Ability for Native Support for backend with Node.js
- Delivery Models with Clear Scope (Dedicated Team & Fixed Scope)
