Chapel is described as 'Programming language designed for productive parallel computing at scale' and is a programming language in the development category. There are more than 50 alternatives to Chapel for a variety of platforms, including Windows, Linux, Mac, BSD and Web-based apps. The best Chapel alternative is Python, which is both free and Open Source. Other great apps like Chapel are JavaScript, Java, C (programming language) and Rust.
