Top 10 Open Source Shopping Cart Plugins for Web

1. WooCommerce

WooCommerce remains the most direct entry point for WordPress-based stores in Malaysia. It runs on a standard LAMP stack—PHP 8.2, MariaDB 10.6, and Nginx—which aligns with what Exabytes and Shinjiru offer on their RM99/month shared plans. The plugin’s real strength is the My Akaun FPX gateway plugin and the Touch ‘n Go eWallet checkout module from Razer Merchant Services. For delivery, you can pull EasyParcel’s shipping API directly inside the cart, which gives you on-site rates for J&T, Pos Laju, and DHL eCommerce. The store admin dashboard supports minimum order amounts in MYR, plus a GST/SST calculation field that you can keep active even after e-invoicing mandates start to roll out.

2. OpenCart

OpenCart is lightweight, with no composer dependencies and a simple file-based structure. Malaysian hosting providers commonly offer one-click OpenCart installs on shared environments, and the actual runtime footprint is about 98MB RAM with 512MB allocated to PHP. The marketplace has a mature Malaysia-specific payment extension set: SenangPay, BillPlz, and eGHL all publish OpenCart modules. OpenCart uses a router pattern that makes it predictable to extend—you can write a custom shipping module for Lalamove in a single controller file. Its session-based caching, however, will force you to use Redis after roughly 10,000 SKUs. Use the default `ocmod` system for XML modifications, not direct core file edits, because open-source package updates will clobber your changes on patch releases.

3. PrestaShop

PrestaShop is a PHP MVC framework that ships with over 300 built-in features, including a currency converter that handles MYR conversion well, even with volative FX rates against the USD. The theme subsystem uses Smarty templates, which means you can alter the checkout layout for left-aligned local e-wallet buttons without touching module logic. For Malaysia, the `ps_wirepayment` core module needs to be replaced with a custom module that talks to PayNet’s DuitNow QR endpoint. PrestaShop’s default URLs can grow long, and since Malaysian shoppers often come from Facebook Marketplace links with UTM parameters, you’ll want to enable canonical redirects via the `ps_mainmenu` and Apache rewrite rules. The plugin supports multistore, so one database can serve a KL flagship store and a Penang-facing subdomain.

4. Magento Open Source

Magento Open Source is the descendant of the original Magento CE, now maintained by Adobe but still fully AGPL-licensed. It is the only cart on this list with built-in staged content staging and a customer-segmentation API that is genuinely useful for a Klang Valley omnichannel setup. You will need a minimum 4GB RAM and a VPS from Vultr or DigitalOcean in Singapore to run it with Elasticsearch 7.x for catalog search. Magento’s payment provider architecture relies on a Vault module that supports tokenized card storage, which allows you to store cards for repeat customers while remaining PCI-SA Q3 compliant. The downside is the learning curve for localized tax modules—you have to manually configure SST states or use a third-party extension like Mageplaza’s Malaysian Tax Extension.

5. Drupal Commerce

Drupal Commerce is a backend module, not a full cart out of the box. It hooks into Drupal’s Entity API, so product attributes, customers, orders, and payment transactions all map to Drupal’s schema. For a web team already maintaining a Drupal CMS in Kuala Lumpur, this eliminates the need to build a separate store microservice. You can add the `commerce_klaviyo` module to sync customer analytics with email marketing, but the module’s real value is the `commerce_payment` API’s pluggability—you can write a custom plugin that connects to Bayar or iPay88 with only 16 lines of code. The main operational constraint is that Drupal Commerce requires a Composer-managed install, which means shared hosting is not viable; you need a proper GitOps workflow through a CI pipeline.

6. Sylius

Sylius is a headless-oriented PHP e-commerce framework built on Symfony 6.1. It does not provide a front end. This gives you full control over the storefront and allows your backend to be a pure REST/GraphQL API. Sylius runs perfectly with PHP 8.2 and PostgreSQL 15, and it uses the Symfony Messenger component for async job queues. If you operate a multi-language store in Malaysia (Bahasa Malaysia, English, Mandarin), you will appreciate Sylius’s built-in locale-aware routing. Its admin panel supports RBAC so you can give your warehouse staff in Shah Alam limited access to only order and inventory endpoints. However, do not expect a plug-and-play experience—you are committing to Symfony architecture and must be prepared to write custom Twig templates for every page.

7. Bagisto

Bagisto is a Laravel-based open-source e-commerce framework. It uses an in-built Vue.js admin panel, which means the control panel is a progressive web app—responsive on tablets. For a logistics context in Malaysia, Bagisto has a modular core that supports multi-warehouse inventory, so you can track physical stock across a main store in Puchong and a fulfillment hub in Johor Baru. The `bagisto-custom-shipping` package lets you create custom shipping calculators that handle tablerates by postcode, which is useful for East Malaysia (Sabah/Sarawak surcharges). Bagisto’s ability to extend uses standard Laravel service providers, and you can drop in a package like `barryvdh/laravel-dompdf` to convert invoices into PDFs automatically. The codebase is well-structured for a small dedicated team but not for enterprises needing complex ERP integrations.

8. Medusa.js

Medusa.js is an open-source headless commerce Node.js framework. It is based on Node.js 18 and uses PostgreSQL with TypeORM. Medusa treats the cart, order, and inventory as core domains, but you will write all your own UI components. There is a vibrant ecosystem of plugins: a payment plugin for PPOM that redirects to PayPal, and a manual shipping plugin that allows you to connect with Lalamove via their RESTful API. Because Medusa is written in TypeScript, you can extend the `CartService` with a custom `validateLocalShipping()` method that calls a local delivery provider’s API in milliseconds, all within the same language as your API. Hosting is simple—deploy to a Singapore-based node on Cloud Run or a Docker container via Heroku. The tradeoff is that Medusa is you have to handle taxes yourself; Malaysia’s 8% SST calculation is not built in.

9. NopCommerce

NopCommerce runs on ASP.NET Core 8.0 and uses MySQL or SQL Server as its data store. It is a fully featured cart with a very mature admin panel, including a segment builder for customer roles and price ranges. For a middle-sized Malaysian retailer using Windows hosting, NopCommerce is arguably the most comfortable fit—you can deploy to Azure’s standard Windows App Service Plan in Southeast Asia at around RM300/month. The plugin ecosystem is not as broad as WooCommerce’s, but NopCommerce has a built-in URL rewrite engine and supports multi-store. If you want to use e-wallet payments, you will need to integrate directly with Razer’s .NET SDK, and you will have to write the webhook handler in C#. The major operational benefit is that NopCommerce ships with a SQL database-first migration system—no ORM surprises.

10. Spree Commerce

Spree Commerce is an open-source Ruby on Rails e-commerce framework, and it is the only Rails-based cart on this list. If your web team primarily writes Ruby, Spree will feel like a natural fit. It uses the Solidus fork for active maintenance, but Spree’s core storefront has a well-structured MySQL schema. The admin supports multi-currency and multi-language, which satisfies a Malaysia-based store selling to Singapore and Thailand. Spree has no built-in chat for support; you will rely on GitHub discussions and its community for issues. That said, you get a reliable payment system with a credit-card processor adapter, and you can connect to Stripe in Singapore to process SGP cards. The real challenge is that you will host this on a Linux VPS and must know how to manage Sidekiq background jobs to handle order emails and inventory updates.
