A free, cross-platform IDE for Java, PHP, web, and desktop projects.

Apache NetBeans is an open-source integrated development environment for writing, editing, refactoring, and building software. It supports Java along with PHP, JavaScript, HTML5, CSS, and other languages, and also serves as a tooling platform and application framework.

Why it stands out

  • Apache Software Foundation project with an open governance and contribution model.
  • Combines an IDE, extensible tooling platform, and application framework rather than only a code editor.
  • Strong Java heritage while still covering PHP and common web development languages.
  • Runs across major desktop operating systems that support Java, including Windows, Linux, macOS, and BSD.
  • Maintains plugin and source-building paths for users who need to extend or customize the environment.

Good to know

  • Requires a desktop installation on an operating system with Java support.
  • The site notes that tutorials are being reviewed, so some learning material may be in transition.
  • Language support is broad but the homepage highlights Java, PHP, JavaScript, HTML5, and CSS rather than every modern stack.

Under the radar: Before assuming a framework or language feature is missing, check the Plugins section; NetBeans capabilities often come through add-ons maintained outside the core download.
