NetBeans IDE Updates and Improvements

Java Application Development
Open Source

If you're developing in Java, having a productivity-improving IDE is a must. While IntelliJ IDEA dominates market share, there are other options like the free and open source NetBeans IDE that can help developers improve their development output without the price tag.

But how do NetBeans IDE features keep pace with their paid counterparts? And does the new NetBeans release cadence make them better poised for success within the Java IDE landscape? In this blog, we dive in on the NetBeans IDE features and functionalities introduced from 12.0 to 12.5, and what the next LTS version, NetBeans 13.0, might look like.

What Is NetBeans?

The Apache NetBeans IDE represents a free and open-source development environment, tooling platform, and application framework. NetBeans is typically used by Java developers, but it can also accommodate JavaScript, PHP, HTML5, CSS, and other languages.

Market Share

According to our 2021 Java Developer Productivity Report, JRebel enjoys a 13% of Java IDE market share. For comparison, our 2020 Java Developer Productivity Report had 4% of Java IDE market share.

This increase indicates not only a marked improvement to the IDE, but also a conscious effort to keep the IDE updated alongside other new Java tool versions.

NetBeans Release Cadence

According to the public NetBeans confluence page, the NetBeans release cadence typically follows a quarterly cadence, with one LTS release every year. Non-LTS releases are considered "Feature Releases", with those features then being folded into the yearly LTS release.

For 2021, NetBeans decided to forego an LTS release. The next LTS release will be 13.0, and be released sometime in 2022. As a consequence, there will be additional "Feature Releases" incorporated into the 13.0 release, unless additional adjustments are made to the release roadmap.

When to Use NetBeans

NetBeans is a good choice for developers on a budget, or those who need a lightweight IDE. Because it's a free and open source Java IDE, it can be cheaper to operate than paid versions of IDEs like IntelliJ IDEA.

For developers that need a more robust IDE, and have the budget to pay for them, IntelliJ IDEA will likely be the more favored option. If you want more information on how to choose between Java IDEs, be sure to read our blog.

Looking Ahead to NetBeans 13.0

At a minimum, users can expect the features and improvements found in NetBeans 12.1, 12.2, 12.3, 12.4, and 12.5 to be incorporated into NetBeans 13.0. Because the NetBeans team put a LTS release pause place for 2021, it's also possible that versions 12.6 and 12.7 may be released before 13.0 is released in 2022.
