There is no single meaning of “free ecommerce platform.” It can mean free, open-source software that still needs paid hosting, a hosted storefront with no monthly platform charge, or a limited free tier that may not support the store you need. Those options have different costs and obligations, so an eight-platform ranking would imply more current plan and checkout verification than the available evidence supports.
This guide focuses on the options with the clearest source-backed details: Square Online and WooCommerce, with qualified notes on PrestaShop, Big Cartel, and Ecwid. Pricing examples are specific to Canada and the UK where stated; they are not interchangeable or global rates. Check each provider’s current terms for your country before committing.
What “free” means when you run an online store
Compare the way a platform charges before comparing its headline price. A no-cost download is not a hosted store, and a free hosted plan is not necessarily free to operate.
- Open-source software: The software may cost nothing to download, but you arrange hosting and may pay for a domain, extensions, design work, maintenance, or support.
- Hosted plan with no monthly platform charge: The provider hosts the storefront, but payment processing can still cost money. Features or selling options may also vary by country and plan.
- Limited free tier: A free plan may restrict products, features, branding, or other capabilities. Verify whether it supports checkout and suits your catalog before building around it.
For a personal-finance decision, the useful comparison is the expected operating cost at your likely sales volume—not just the monthly subscription line.

Options with the clearest pricing evidence
Square Online: a hosted option with country-specific processing rates
Square’s Canadian plans page advertises a free plan and lists inventory management, an online shopping cart, and social selling features. It lists a processing rate of 2.8% + 30¢ per transaction. Those details apply to the Canadian page; confirm the current terms for your location at Square Canada’s online-store plans.
Square’s UK page lists 1.4% + 25p for UK cards and 2.5% + 25p for non-UK cards. These are UK-specific examples, not rates to apply elsewhere. Check Square UK’s online-store page for the applicable terms.
A processing fee is charged on transactions, so its effect grows with sales. For example, using the Canadian rate as an illustration only, a $100 transaction would incur $3.10 in processing fees before any other costs. This calculation does not establish the complete cost of a Square store or apply outside the Canadian pricing example.
WooCommerce: free software, separately arranged store infrastructure
WooCommerce describes itself as free, open-source ecommerce software for WordPress. That means the software itself has no listed purchase price; it does not mean every part of running a store is free. See WooCommerce’s pricing page.

- WordPress hosting and a domain name
- Paid extensions or themes, if you need features beyond what you can use at no charge
- Payment processing
- Technical upkeep and support, whether handled by you or someone you hire
There is no universal total supported for these costs: the amount depends on your choices and needs. WooCommerce can suit a merchant who wants control over the site and is prepared to manage its infrastructure, but it is not equivalent to a hosted plan that bundles a storefront.
Other names to investigate, not verified free-plan recommendations
PrestaShop
A 2026 comparison describes PrestaShop Classic as free to download and use, while noting potential costs for hosting, a domain, modules, themes, payment processing, and developer support. This is secondary reporting, not a confirmed statement of current official plan terms. Read the comparison, then verify the current offering directly with PrestaShop before making a cost or feature decision.
Big Cartel and Ecwid
A third-party comparison characterizes Big Cartel as an option with no platform fees and Ecwid’s free plan as limited. That does not establish their current product ceilings or feature entitlements. Check the vendors’ current plan documentation before relying on either description. The comparison is at Ecommerce-Platforms.com.

Wix and other website builders
A commercial roundup lists Wix among software with free availability, but the listing does not establish that every free version allows a live ecommerce checkout. A free website plan and a free commerce-enabled plan are different things. The Shopify Canada roundup is a starting point for identifying candidates, not proof of current checkout eligibility or plan limits.

- Confirm that the free option supports checkout in your country. A free website or software download is not enough if you cannot accept orders under that plan.
- Write down all charges separately. Include the platform subscription, payment processing, hosting, domain, add-ons, design, maintenance, and support where they apply. Do not treat transaction processing as a platform fee.
- Estimate fees against your expected orders. Multiply the order value and volume you expect by the provider’s applicable processing terms. Use the rate for your country and card type, not a figure from another market.
- Check operational limits and upgrade triggers. Confirm product or order caps, custom-domain rules, branding, sales channels, and which tools are included. The cited comparisons do not establish a complete current limits matrix.
- Account for the work you will do yourself. Self-hosted software may reduce software charges but requires you to arrange and maintain the store environment; hosted options shift more infrastructure responsibility to the provider.
Plan terms and rates can change. Confirm current details on the provider’s own site for the country where you will sell, especially before migrating a catalog or investing in customizations.
Quick Recap
Which kind of free platform fits your situation?
- Consider Square Online if you want a hosted option and its features and terms work in your market. Include processing fees in your sales-cost estimate.
- Consider WooCommerce if you want open-source WordPress ecommerce and are comfortable arranging hosting, a domain, extensions, and ongoing technical care as needed.
- Investigate PrestaShop, Big Cartel, or Ecwid only after confirming current plan availability, checkout eligibility, limits, and charges with the vendor.
- Do not assume a free website-builder plan can sell products. Verify that the specific plan includes ecommerce checkout.
