Zen Cart is an online store management system.

Support is provided for numerous languages and currencies, and it is freely available under the GNU General Public License.

[3] Zen Cart is a software fork that branched from osCommerce in 2003.

[6] The release of the 1.3.x series further differentiated Zen Cart by moving the template system from its historic tables-based layout approach to one that is largely CSS-based.

As support for Zen Cart dropped in recent years, many third party companies are creating Zencart plugins and modules[3] that can help users solve problems like installing reCAPTCHA v3[7]
