The short version

  • Each has a real cost: OpenCart extensions modify core behaviour through an XML patching system, so two modules that patch the same file conflict in ways that surface as broken checkout rather than as an installation error, and resolving that requires a developer reading both patches.; Temu temu is owned by PDD Holdings, the same corporate group behind Chinese app Pinduoduo, and security researchers and app reviewers have raised documented concerns about the scope of data and device permissions the apps in this family request.
  • They diverge on capability: OpenCart covers MIT licensed source, Temu covers General merchandise marketplace.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OpenCart

  • Extensions modify core behaviour through an XML patching system, so two modules that patch the same file conflict in ways that surface as broken checkout rather than as an installation error, and resolving that requires a developer reading both patches.
  • Major version upgrades have broken third party extension compatibility, so moving between them means re-purchasing or re-commissioning modules and effectively rebuilding parts of the store rather than clicking update.
  • Hosting, patching, backups and PCI scope are all your responsibility, so a security update you postpone is a breach you own, and there is no vendor obligation to notify or protect you.
  • Extension quality on the marketplace is uneven and modules are sold as one-off purchases with no guaranteed maintenance, so a module central to your store can simply stop being updated and leave you holding the code.
  • The core project is maintained by a very small team relative to the platforms it competes with, so security fixes, compatibility with new PHP versions and feature work all arrive at a pace you cannot influence or pay to accelerate.

Temu

  • Temu is owned by PDD Holdings, the same corporate group behind Chinese app Pinduoduo, and security researchers and app reviewers have raised documented concerns about the scope of data and device permissions the apps in this family request.
  • Consumer safety testing by regulators and watchdog groups has flagged some products sold on Temu for exceeding legal limits on substances such as lead in specific items, similar to findings on other ultra-low-cost marketplaces.
  • Regulators in the EU and US have investigated or fined Temu over misleading discount claims and dark pattern design, including inflated reference prices used to make discounts look larger than they are.
  • Shipping times are long by mainstream e-commerce standards, commonly one to two weeks or more, and buyer recourse for a delayed, missing or damaged order is limited compared with domestic retailers.
  • Changes to duty-free import thresholds in the US and EU have added customs fees to some orders, eroding the headline low price advertised at checkout.

Answered from the vendors’ own pages

OpenCart: Is OpenCart really free?

The software is MIT licensed with no paid edition. The costs are hosting, extensions, and a developer, and for a low volume store those can exceed a SaaS subscription.

Temu: Who owns Temu?

Temu is operated by Whaleco Inc., a subsidiary of PDD Holdings, the parent company of the Chinese shopping app Pinduoduo.

OpenCart: Does it charge transaction fees?

No. There is no platform cut and no surcharge for using your own payment gateway, which is the main financial argument for self-hosting at volume.

Temu: Is Temu safe to use in terms of data privacy?

Security researchers have flagged the scope of permissions requested by Temu and related PDD Holdings apps as a documented concern; the company disputes characterisations of its apps as malicious.

OpenCart: How hard is customisation?

Theme changes are ordinary PHP templates and are approachable. Changing behaviour means the OCMod patching system, which conflicts between extensions and needs a developer.

Temu: Are Temu products safe?

Consumer safety testing has found some specific products exceeding legal limits for substances such as lead, similar to findings reported on other ultra-low-cost marketplaces; safety varies by product.

OpenCart: What is the biggest hidden cost?

Upgrades. Version transitions have broken extension compatibility before, so budget for a partial rebuild rather than assuming updates are routine maintenance.
