Netbeans Editor Features Review

Netbeans is a Java-based integrated programming environment (IDE). Netbeans is free, open source and cross-platform (Mac, Windows and Linux).

This review is an update of a previous 2013 article and is based on features I require of an advanced text editor. A list of required features was created after using different editors. Some features require extensions or plug-ins.

Apache Netbeans is a free IDE for Java from There are downloadable packages for Linux, Mac and Windows systems. Netbeans can easily be extended by plug-ins to develop applications in other programming languages.

Three bias elimination steps were utilized. The editor was used for at least three years on different platforms. Attempts were made to get stable plug-ins for missing features. The same editor was compared between the one in the repository, the developers website, and the compiled version if applicable.

Selecting Editor Version

Netbeans was downloaded from the developer’s website for portability. Netbeans and its plug-ins are less bloated than in the last review. I enjoyed using Netbeans from version 8.2 that it is now my preferred PHP IDE. I even put up with the reinstall every time as it does not come with an auto-update feature..

Netbeans was installed in my home folder as I no longer distro-hop. All plug-ins such as PHP and Git were pre-installed once and never require re-installation. I even submitted a bug requesting the JSCH Library update in 2022.
