When it comes to software development, cross-platform is a term commonly used. It refers to an application or software that can work on different operating systems or platforms. However, the term cross-platform can be replaced by some other synonyms that add more meaning or depth to what a program can do. Some common synonyms for cross-platform include multiplatform, platform-independent, or even device-agnostic. Multiplatform emphasizes that software can function on numerous platforms. Platform-independent refers to code that's written to function on as many operating systems and hardware as possible. Device-agnostic means a program can operate on every type of device or machine, regardless of the operating system or hardware. These synonyms can help explain how a program works and what it can achieve, beyond merely supporting multiple platforms.
