CBSplit does not run React applications natively like a full framework host (Next.js or Create React App). Instead, React code can be used inside CBSplit through embedded HTML/JS bundles.

• Direct React: There is no built-in React runtime inside CBSplit. React apps must be compiled and bundled before use.
• How to use: You can build your React components locally, then embed the compiled JavaScript (and any CSS) into CBSplit pages or layouts.
• Flexibility: This allows you to drop React widgets, interactive forms, or components into landing pages while still using CBSplit’s editor and split testing.
• Limitations: Features like server-side rendering (SSR) or static export from Next.js are not supported inside CBSplit. Only the client-side compiled output can be used.

In short: CBSplit does not host React directly, but you can embed React components by including their compiled HTML/JS bundles into CBSplit pages.
