OpenCart

What is OpenCart?

OpenCart is a free, open-source online store management system built in PHP with MySQL/MariaDB or PostgreSQL. It lets merchants create and run one or more storefronts from a single back-end, with support for multiple languages, currencies, payment gateways, and shipping methods. Originally created in 1998 and revived in 2005 by developer Daniel Kerr, it is maintained by OpenCart Limited in Hong Kong and distributed under the GNU General Public License, backed by a large extension and theme marketplace.

How OpenCart works with TikTok

OpenCart offers an official TikTok integration that connects a store to TikTok For Business, TikTok Ads Manager, and TikTok Business Center. Merchants can install the TikTok Pixel and Events API for browser and server-side tracking of events like View Content, Add to Cart, Start Checkout, and Purchase, and can enable Advanced Matching for higher conversion match rates. The integration also syncs the OpenCart product catalog to TikTok Business Center and helps merchants launch Lead Generation and Conversion ad campaigns to reach TikTok audiences.

Pricing

The OpenCart core platform is free and open-source under the GNU GPL, and the official TikTok extension is available to install at no listed cost.

Best for

Merchants and store owners who want a self-hosted, open-source e-commerce platform with full control over their storefront, and who want to connect that store natively to TikTok for pixel tracking, catalog sync, and advertising.
