The Best eCommerce Platform in 2021 – 12 Top Picks

Best eCommerce Platform

Use Rapyd’s comprehensive comparison to select the best ecommerce solution for your business needs.

Choosing the best B2C ecommerce platform to grow online sales is a key decision for a merchant. However, the number of ecommerce platforms has skyrocketed in the past decade. To make the process easy, we’ve put together our list of 12 of the top ecommerce platforms.

What is a B2C eCommerce Platform?

B2C ecommerce platforms (Also known as shopping cart software) differ from standard website builders because they provide specific features for online sellers, including things like payments application integrations, comprehensive product catalogues, and in-platform seller marketing. Traditional website platforms and CMS systems are built for a wider range of needs but lack the specialized functionality ecommerce platforms provide.

eCommerce platforms from WooCommerce, Magento, Wix, Shopify and others are dramatically simplifying online selling globally for merchants and making it easy to launch stores online. Many platforms are also giving enterprise merchants the ability to customize their ecommerce stacks in ways that best suit their needs.

The Best Free eCommerce Platforms

Many ecommerce platforms cost little to nothing to get up and running. If you have a limited budget — or just want to get set up to sell online fast — you can consider the following free options. These can also be a good departure point for start-up businesses or businesses looking to move from brick-and-mortar to online sales for the first time. While these solutions are free, merchants will still have to pay transaction fees.




G2 describes Opencart as “an easy-to-use, powerful, open-source online store management program”. OpenCart can support multiple stores from a single interface while customizing and localizing each store, which can be especially useful for merchants with multiple independent brands and retailers that sell cross-border.

OpenCart has a $99 per month service available for businesses that would like dedicated customer support. There are also transaction fees that can vary based on the payment methods and the gateway(s) used.

  • Key features: Shopping cart management, email integration, reporting, localization
  • Pros: More than 13,000 modules and themes, easy administration
  • Cons: Some extensions have security vulnerabilities and the costs of extensions can add up quickly.




WooCommerce describes itself as an open-source commerce solution built on WordPress. So you will need to have hosting and a WordPress site to use it. Its ubiquity on WordPress ecommerce sites gives it a massive market share (28%) and therefore a robust community of developers, plugins and resources to support it.

WooCommerce has no setup charge or monthly fees. Businesses pay 2.9% + $0.30 for each transaction made with U.S.-issued credit cards or debit cards. For cards issued outside the U.S., there’s an additional 1% fee. Other payment gateways are also available for international transactions and local payment methods.

  • Key features: Storefront design, order management, product search and filters
  • Pros: Great for WordPress and rich in-store themes
  • Cons: Not suitable for non-WordPress websites



Magento (Open Source)

Adobe offers two ecommerce platform solutions, Magento Open Source and Magento Commerce. While Commerce will set you back over $20,000 a year, you can self-host the slimmed-down, open-source platform for free. It won’t include Magento Customer support or many of the features that make Magento Commerce a powerhouse enterprise ecommerce platform, but it’s great for companies who want to start small and upgrade down the road without switching platforms.

With Magento Open Source, you will need to pay for hosting from a third-party hosting provider. Magento Open Source doesn’t charge transaction fees, other than the fees charged by the payment gateway, which can vary.

  • Key features: SEO, promotions and discounts, shipping options
  • Pros: Large developer community and support forums, a large selection of extensions
  • Cons: Requires technical expertise to implement and maintain

The Best Website Builders for B2C eCommerce

Squarespace Commerce

  • Key features: Robust plugin marketplace, SEO
  • Pros: Great store editor, user-friendly interface, abandoned carts recovery
  • Cons: Limited inventory management and multichannel capabilities
  • Pricing: From $23 per month

As your business grows, there will come a time where you need a solution that is built for scale. You’ll likely need the ability to customize your store and checkout experience more deeply, especially if you’re a business that’s selling a wide range of products online. This is where robust, all-in-one solutions come in.

They are known for delivering a great experience to their clients, along with an interface that is easy to use, customize and extend.

The Best B2C Platforms for Composable Commerce

Composable or ‘headless’ commerce are two terms that have become common in ecommerce technology circles. Composable commerce is an approach where a company assembles different, user-interface-free business services and packages them together to create a solution that is best-of-breed for their unique needs and delivers a better customer experience across all channels.




commercetools provides cloud-native APIs for large enterprise clients as an alternative to a fully custom build. It is a developer-friendly solution that utilizes a microservices approach. It is versionless, elastic and extremely cost-effective.

commercetools relies on a customer’s existing enterprise BPS system for workflow management and requires deep developer expertise.
