  • Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor.
  • Public sandboxes are visible to others by default, which is not ideal for proprietary code.

  • Distributed under the Modified BSD License, also called the PHP License version 4, per php.net/license/; there is no paid tier or vendor price to compare
  • PHP 8.2 lost active support on 31 Dec 2024 and enters full end of life on 31 Dec 2026, with only security fixes since, per php.net/supported-versions.php (Aug 2026)
