When your React app needs work

If your app was built on Create React App, an older Next.js or unpatched Server Components, it's time to bring it up to date. We'll fix it or rebuild it properly.

  • Your app was built on Create React App, which was deprecated in 2025.

  • You haven't patched the Server Components vulnerabilities disclosed in December 2025.

  • Your pages are slow, and it shows in your search rankings.

  • You need a new React front end on an existing back end.

An open-source JavaScript library for building user interfaces, now looked after by the React Foundation.

Product and development teams building web apps, from start-ups to the largest platforms.

  1. React

    The interface library at the centre of it all.

  2. Next.js

    A React framework for server rendering, routing and search-friendly pages.

  3. Server Components

    Parts of the page rendered on the server, so less code reaches the browser.

  4. React Compiler

    Automatic performance tuning, with fewer manual fixes.

  5. React Native

    React for iOS and Android apps.

  6. Vite

    A fast build tool, and the usual replacement for Create React App.

  1. Front ends and web apps

    React front ends on any back end, like Leafletdrop's map-based ordering on Symfony.

  2. Upgrades and security

    Moves off Create React App, Next.js upgrades and security patches.

  3. Performance

    Faster pages and better Core Web Vitals, measured before and after.

  4. Support

    Regular updates and fixes, so you don't fall behind again.

The things people usually ask

Plain answers on how React works, what it costs and what we need from you. Anything else, just ask.

Are we affected by the Server Components vulnerabilities?

Check if your app uses React Server Components or a framework built on them, such as recent versions of Next.js. Critical fixes came out in December 2025. We can check your versions and patch them.

Create React App is deprecated. Do we need to rebuild?

Not usually. Most apps can move to Vite or a framework like Next.js and keep their components. We'll plan the move so nothing breaks.

Can React help our SEO?

Yes, if pages are rendered on the server. A React app that only renders in the browser is harder for search engines and AI tools to read.

React or Vue?

Both are good choices. React has a bigger ecosystem, and React Native for mobile. Vue is often quicker to work with alongside Laravel. We'll recommend one based on your team and what's already built.
