Web Components vs React – When to Choose Which?

Hi everyone, 

We’re starting a new front-end project and trying to decide between Web Components vs React. Our team has experience with React, but we’re also considering Web Components because of their framework-agnostic nature and potential for reuse across different apps in the future. 

A few things we’re trying to evaluate: 

• performance differences in real-world apps 

• ease of integration in an existing react project 

• long-term maintainability 

• learning curve for the team 

• any limitations compared to the react version 

Has anyone worked with both? In what scenarios would you recommend Web Components vs React components? Thanks! 

Hello Alex,

If you’re trying to decide between Web Components and React, the first thing to understand is that they’re not really competing technologies in the way people often think. 

React is a framework (or library) for building entire applications. It gives you structure, rendering logic, state management patterns, and a huge ecosystem around routing, tooling, SSR, and more. 

Web Components, on the other hand, are a browser standard. They’re a way to create reusable custom elements that work anywhere – in React, Angular, Vue, or plain JavaScript. They’re not an application framework. They’re more like portable UI building blocks. 

When people ask about performance, the honest answer is that both can be extremely fast. React is highly optimized and mature. Well-built Web Components can be just as efficient because they interact directly with the DOM and encapsulate their own logic. In data-heavy scenarios like grids and dashboards, performance usually depends much more on virtualization and rendering strategy than whether you’re using React components or Web Components. 

If you’re building a React application and your whole team works in React, using React components makes perfect sense. You’ll get tight integration with the ecosystem and a familiar development model. 

But if you need framework flexibility (for example, if you’re building a design system, working in a micro-frontend architecture, or want the option to reuse components across different frameworks), Web Components can give you long-term portability that React-only components don’t. 

From the Ignite UI perspective, this is exactly why we support both. It’s not an either/or decision. Ignite UI for React gives you React-native components that feel natural inside a React app. Ignite UI for Web Components gives you standard-based components that can run inside React but also Angular, Blazor, or other environments. 

That means you could build your app in React today, use Web Components for your UI layer, and still have flexibility later if your architecture changes. Or you can stay fully in React and use the React-specific components. The choice depends on your goals around portability and long-term maintainability. 

In modern front-end architectures, it’s actually common to combine them – React for application composition, Web Components for reusable, framework-agnostic UI.
