Can I use React + Capacitor to build Android, iOS, and Web apps from the same codebase?

I am planning to build an application using React (ReactJS for web).

I would like to:

Use the same React codebase for a web app

Convert the project into an Android app

Convert the same project into an iOS app

I came across Capacitor by Ionic, which seems to wrap a web app into native Android and iOS projects.

My questions are:

Can I use React + Capacitor to generate Android and iOS apps from the same codebase?

Will the same project still work as a normal web app?

Are there any major limitations when using Capacitor compared to React Native?

Do I need a Mac to build the iOS version?

I’m mainly trying to understand if this approach is production-ready and commonly used.

Any clarification would be appreciated.
