Back in the days of Objective C/Swift and Java/Kotlin as primary languages for mobile development, building apps was expensive. You had to build two separate apps, which obviously meant doing the work twice.

You might assume that every cross-platform framework can perform some things and offers some features essential for the job, and you have a point.

Java is an open-source software development kit which enables smooth and easy cross-platform mobile app development. You can build high quality natively compiled apps for iOS and Android quickly, without having to write the code for the two apps separately. All you need is one codebase for both platforms.

Next.js is an open-source React-based framework used for building server-rendered (SSR) or statically-generated (SSG) web applications. It's built on top of Node.js and provides a simple and efficient way to build performant and scalable web applications.

Gatsby JS is built on React and uses GraphQL to query data from multiple sources, such as APIs, databases, or Markdown files. It provides a fast, optimized, and secure website experience, leveraging technologies such as server-side rendering, pre-fetching, and code splitting.
