In July 2025, is there a way to build once for Web, iOS and Android or do I need to build separate apps? + Do I need Mac for builds?

Certainly! Here’s a professional, well-structured WordPress blog article based on your original Reddit post:

Streamlining Mobile and Web App Development in 2025: Is Cross-Platform Building a Reality?

In the rapidly evolving landscape of software development, entrepreneurs and developers alike are constantly seeking ways to optimize their workflow, reduce costs, and accelerate time-to-market. As of mid-2025, a common question arises: Is it possible to build a single codebase that supports web, iOS, and Android platforms, or do developers still need to create separate applications? Additionally, what are the current requirements regarding development hardware, such as the need for a Mac to build iOS apps?

The Challenge of Cross-Platform Development in 2025

With the proliferation of devices and platforms, developing native apps for each OS can be resource-intensive. Historically, developers relied on platform-specific languages and environments—Swift or Objective-C for iOS, Java or Kotlin for Android, and various web technologies for desktop and browser-based applications. This often meant maintaining multiple codebases, increased development times, and elevated costs.

Are There Cross-Platform Solutions to Build Once, Deploy Everywhere?

Fortunately, recent advancements have significantly improved the landscape of cross-platform development:

React Native: Established as a leading framework, React Native allows developers to write code in JavaScript (or TypeScript) and deploy to both iOS and Android. Recent updates have enhanced its performance and compatibility, making it a viable option for many new projects.
Flutter: Google’s UI toolkit has gained popularity due to its performance and expressive design capabilities. Using Dart, Flutter enables developers to build natively compiled applications for mobile, web, and desktop from a single codebase.
Progressive Web Apps (PWAs): For certain applications, PWAs offer a web-centric approach that can function across browsers and devices without requiring app store deployment. They minimize the need for separate native apps if offline functionality and native features are not critical.

Can You Develop Web and Mobile Apps Simultaneously?

Yes. Many frameworks and tools now support the concurrent development of web and mobile applications:

React Native + React: Combining React Native for mobile with React for web can streamline development processes, sharing components and logic where appropriate.
Flutter Web: Flutter’s web support enables you to compile your app for browsers alongside mobile platforms, reducing the need for separate codebases.
Multi-platform Tools: Platforms like Ionic, Xamarin
