Apache NetBeans vs Xdebug

Apache NetBeans is a development environment, tooling platform, and application framework for Linux, macOS, and Windows. Its editor highlights code by syntax and meaning and supports refactoring. Editors, wizards, and templates cover Java, PHP, and other languages, with plugins and linked support for JavaFX and JavaScript. The NetBeans Platform is a modular framework for Swing applications, with state saving, menus, toolbars, keyboard shortcuts, and window management. The IDE and Platform are free for commercial and non-commercial use under the Apache License; the listed plan is free. Apache NetBeans 31, dated August 10, 2026, supports running on JDK 26, 25, or 21, with initial support for JDK 27. Downloads include platform-independent binary and source ZIPs, plus linked installers for Windows, macOS, and Linux. Those installers are provided by committers for convenience, not as Apache Software Foundation releases. The release page provides SHA-512 hashes and PGP signatures. Windows/ARM is not fully supported, and older releases are no longer supported.

Xdebug is a PHP extension that adds debugging and analysis features to PHP development. Its step debugger lets developers move through code interactively to examine control flow and data structures. It improves var_dump() output and adds stack traces for notices, warnings, errors, and exceptions. Function tracing can record calls, arguments, and invocation locations, with optional variable assignments and return values. The profiler reports execution and memory use in Cachegrind-compatible files, while code coverage can show what runs during PHPUnit tests. Xdebug communicates with IDEs through DBGp, a protocol supported by nearly every PHP IDE, including Visual Studio Code and PhpStorm. Installation instructions cover Linux, macOS, Windows, and Unix-like systems, with compatibility information organized by PHP version. Xdebug itself is free. Paid Pro costs £200 per year for one developer; Business costs £1,000 per year for 2–20 developers. Both paid tiers include email technical support. Xdebug Cloud is described as a relay for situations where a network or firewall blocks direct debugger connections.
