PizzaTier 2.0 is here — everything from Pro, including WooCommerce ordering, is now built into the free plugin. What changed
Support may be delayed — Island Sun Design is based in Hilo, Hawaiʻi, and tropical storm activity may slow our response times. Tickets are still being received and will be answered as soon as possible. Mahalo for your patience.

GPL-2.0

The full source lives on GitHub. Download, use, study, modify, and redistribute it freely under the terms of the GPL.

What GPL-2.0 Means for You

The GNU General Public License (GPL) guarantees your freedom to use, study, share, and modify the software. Key rights under GPL-2.0:

  • Freedom to use — Run the plugin for any purpose, on any number of sites.
  • Freedom to study — Inspect and learn from the source code.
  • Freedom to modify — Customize the plugin to suit any project.
  • Freedom to distribute — Share copies of the original or modified code, provided the GPL license is retained.

These freedoms apply to every part of PizzaTier, including the WooCommerce integration that was previously sold separately as PizzaTierPro. Nothing is held back behind a license.

Copyleft & Distribution

GPL-2.0 is a copyleft license. If a modified or extended version of PizzaTier is distributed, the distribution must also be under GPL-2.0. This ensures derivative works remain open.

Themes, plugins, or code that merely use PizzaTier via its public API, REST endpoints, or shortcodes are not considered derivative works and are not required to be GPL-licensed.
