Apache NetBeans

Apache NetBeans is a free development environment and application framework for programmers working in Java, PHP, and other languages. It is especially suited to developers who want integrated coding tools or a modular framework for Swing applications. Its broad language support and Apache-licensed use make it a practical no-cost option, though release compatibility and Windows/ARM support deserve attention.

Overview

NetBeans brings together an IDE, a tooling platform, and a framework for building Swing applications. The editor combines syntactic and semantic code highlighting with refactoring, while language editors, wizards, and templates extend its reach beyond Java to PHP and other languages. That range makes it a more versatile choice than a narrowly focused Java editor, but its clearest distinction is the ability to use the NetBeans Platform for modular desktop software.

The project’s source code was donated by Oracle to the Apache Software Foundation in 2016, and NetBeans became a top-level Apache project in April 2019. The IDE and Platform are free for commercial and non-commercial use under Apache License 2.0.

Key features

Editing and development tools

Semantic and syntactic highlighting make code structure easier to inspect, while refactoring support helps when changing existing code. A built-in debugger, build tools, and integrated testing tools bring several common development tasks into one environment. This combination is useful for developers who want more than a text editor, although the value of the bundled workflow depends on whether NetBeans suits their language and project setup.

Language support and plugins

Editors, wizards, and templates support Java, PHP, and other languages. The project also points to plugins and describes support for JavaFX and JavaScript, giving developers ways to extend the environment. That breadth is an advantage for mixed-language work, though the stated language range alone does not establish that every workflow has equal depth.

Framework for Swing applications

The NetBeans Platform is a modular framework for Swing applications. It includes capabilities such as state saving, menus, toolbars, keyboard shortcuts, and window management, which can provide a foundation for desktop application structure instead of leaving those concerns entirely to an individual implementation. It is a compelling reason to consider NetBeans for Swing projects, but less relevant if the target is not a Swing application.

Pricing

Apache NetBeans IDE and Platform: free. The plan is free for commercial and non-commercial use under Apache License 2.0, with no paid tier or free-trial period to weigh against it. That makes it accessible for individual developers and teams alike, without a seat price or stated usage cap.

Platforms

NetBeans supports Linux, macOS, and Windows. Apache NetBeans 31, dated August 10, 2026, supports running on JDK 26, 25, or 21, with initial support for JDK 27; checking the required JDK against a project’s environment is essential before adopting that release. Windows/ARM is not currently a fully supported platform, so users on that configuration should be cautious.

The release page offers platform-independent binary and source ZIP files, alongside links to Windows, macOS, and Linux packages supplied by NetBeans committers for convenience rather than released by the Apache Software Foundation. SHA-512 hashes and PGP signatures are provided for verifying downloads. Older releases remain downloadable but are no longer supported, which makes staying on a current release important for users who need project support.

Who it's for

NetBeans suits developers seeking a free IDE with editing, refactoring, debugging, build, and testing tools, particularly those working in Java or PHP. It is also a strong candidate for teams building modular Swing applications who can use the platform’s desktop-app capabilities. It is a less suitable choice for Windows/ARM users who require full platform support or anyone whose required JDK does not align with a supported runtime.

The NetBeans community uses mailing lists as its primary communication channel and welcomes contributions. That approach may suit developers comfortable with community mailing-list support and participation.

Pros and cons

• Pros: Free for commercial and non-commercial use under Apache License 2.0, so there is no licensing fee to weigh against adoption.
• Pros: Editors, wizards, and templates cover Java, PHP, and other languages, making it useful beyond a single-language niche.
• Pros: The Swing application framework includes window management, menus, toolbars, shortcuts, and state saving, offering a meaningful foundation for desktop software.
• Cons: Windows/ARM is not fully supported, which can rule it out for users who need a supported setup on that architecture.
• Cons: NetBeans 31 targets specific JDK versions, so projects on other runtimes may need a different release or environment.
• Cons: Older releases are no longer supported, limiting their suitability for users who need ongoing project support.

Alternatives

For a Java-focused comparison, Eclipse IDE is another free, open-source IDE for Linux, macOS, and Windows. IntelliJ IDEA offers a free core for Java and Kotlin as well as a $100 a year Ultimate subscription, making it an option to compare if that split between core and subscription tiers suits your needs. BlueJ is a free Java development environment designed for beginners, so it is a more targeted alternative for learning-oriented use.

Java-Editor is a free option available on Android, Linux, macOS, and Windows. CS++ Java IDE is a freemium alternative available on iOS, macOS, web, and Windows. MCreator and Processing are free alternatives for readers comparing other software in this category. Spring Tools for Eclipse is a free, open-source option available as an extension and on Linux, macOS, and Windows.

Verdict

Choose Apache NetBeans if you want a capable, no-cost IDE for Java, PHP, and other languages, or if the NetBeans Platform’s modular Swing framework fits your desktop project. Its main appeal is the combination of development tools and commercial-use-friendly licensing at no charge. Look elsewhere if Windows/ARM support is essential or your required JDK does not fit the release’s runtime support.
