Eclipse is described as 'Extensible development platform with runtimes and application frameworks for building, deploying and managing software across the entire software lifecycle. Many people know Eclipse as a Java IDE, but it is much more than that- Eclipse actually consists of over 60' and is a leading IDE in the development category. There are more than 100 alternatives to Eclipse for a variety of platforms, including Windows, Linux, Mac, BSD and Web-based apps. The best Eclipse alternative is Visual Studio Code, which is free. Other great apps like Eclipse are IntelliJ IDEA, VSCodium, Apache NetBeans and Microsoft Visual Studio.
Visual Studio code has rapidly became one of the best cross platform editors on the market, i would say it sits in between a full fledged IDE and a more simple editor. I love it!
