Most Used Ecommerce Platforms in 2027: Market Share and Picks

If you are choosing a store platform for 2027, or selling to people who already run one, the question is not which platform is "best". It is which platform fits a given store's size, catalog, team and growth plan. This guide covers the most used ecommerce platforms right now, what the market share data actually says, how Shopify's pricing is structured, and how to pick without regretting it in 18 months. It also covers how agencies and software vendors can use platform data to find buyers.

Which ecommerce platforms are most used in 2027

The ranking depends on what you measure. Looking at the share of the measurable web, the May 2026 HTTP Archive crawl (analyzed by GravityKit) put the platforms in this order:

Platform	Share of measurable web
WooCommerce	6.64%
Shopify	4.76%
Wix eCommerce	1.48%
Squarespace Commerce	1.12%
Magento / Adobe Commerce	0.38%
BigCommerce	0.14%

Two cautions. First, the analysis notes that Wix and Squarespace are detected at the platform level, so their numbers likely overstate active stores. Second, share of websites is not share of revenue. WooCommerce runs on a huge number of small and hobby shops, while Shopify and BigCommerce skew toward businesses that actually process volume. Treat the table as a map of who is installed, not who is winning in sales.

Why the numbers disagree across sources

Every tracker uses a different detection method, sample and definition of "store". Some count any site with a cart script, others only live checkouts. When you read a claim that one platform has a given percentage, check the crawl date and method before quoting it.

The main platforms, and who each one fits

Shopify

The default choice for brands that want a hosted, low-maintenance store with a large app ecosystem. Its pricing page lists four tiers: Basic at $29 per month on annual billing ($39 monthly), Grow at $79 ($105 monthly), Advanced at $299 ($399 monthly), and Plus from $2,300 per month. Online card rates step down by plan, from 2.9% + 30 cents on Basic to 2.25% + 30 cents on Plus. If you use an outside gateway instead of Shopify Payments, Shopify adds a third-party transaction fee: 2% on Basic, 1% on Grow, 0.6% on Advanced and 0.2% on Plus. Confirm the current numbers on the pricing page before you commit, since they change.

Best for: DTC brands, fast launches, teams without developers. Watch for: app costs that stack up, and the third-party fee if you pick a different gateway.

WooCommerce

A WordPress plugin, so you own the stack and the data. Flexibility is the draw: custom product types, custom checkout logic, any host. The cost is maintenance: hosting, security, updates, plugin conflicts and performance tuning fall on you or your developer.

Best for: content-led stores already on WordPress, merchants who want full control. Watch for: total cost once you add hosting, premium extensions and developer time.

Wix and Squarespace

Both are website builders first, with commerce built in. They suit small catalogs, service businesses that sell a few products, and creators. Check each vendor's current pricing and transaction fee terms, as plans change regularly.

BigCommerce and Adobe Commerce (Magento)

Both target larger or more complex catalogs: B2B pricing, multiple storefronts, heavy customization. BigCommerce is hosted. Adobe Commerce is usually run with a development partner. Their share of the web is small, but the average store on them tends to be larger, which matters if you sell services into the mid-market.

Marketplaces are a separate layer

Amazon, Walmart and others are channels, not store platforms, but most serious sellers run both. If you are comparing channels, see our guide to the best Amazon seller tools and the directory of vetted tools.

How to choose a platform in 2027

Work through these in order:

1. Catalog complexity. A few dozen products with simple variants fits almost anything. Thousands of SKUs, bundles or B2B price lists narrow the field fast.
2. Team skills. If nobody can maintain a server, avoid self-hosted setups.
3. Payments and markets. Check which gateways and currencies are supported where you sell, and what the platform charges on top of the gateway. Our best ecommerce software roundup covers the surrounding stack.
4. Total cost of ownership. Add plan, apps or plugins, theme, developer time and transaction fees across 12 months.
5. Exit cost. Ask how you export products, customers and order history. Migrations are painful, so check this before you sign up, not after.

Common mistakes

• Choosing on the monthly plan price alone and ignoring transaction fees.
• Over-buying enterprise features at launch.
• Picking a platform because a competitor uses it, without checking their volume or team.

What changes going into 2027

Three shifts are worth planning around. Shoppers increasingly discover products through AI answer engines and marketplaces before they ever reach a brand site, so product data quality (clean titles, structured attributes, accurate availability) matters on every platform. Checkout expectations keep rising, with wallets and local payment methods now standard. And merchants are more cost-conscious, so apps and plugins that overlap get cut. If you are choosing now, favor a platform with a healthy integration ecosystem and easy data export, because your needs will change.

A practical test: list the five things your store must do in year two, such as subscriptions, wholesale pricing, multiple currencies, a second storefront or a marketplace feed. Then check whether each one is native, available through a maintained app, or needs custom code. Native and maintained options cost less over time than custom builds.

The GTM angle

Platform choice is one of the cleanest segmentation fields in B2B ecommerce outreach. A Shopify brand has different problems from a WooCommerce shop or a BigCommerce merchant, so your message should change too.

If you sell to ecommerce brands (agencies, apps, 3PLs, email tools, CRO), use platform data like this:

• Build lists by platform and size. Technographic data shows which stack a store runs on. Start with one platform where your product has a native integration, then expand.
• Write platform-specific openers. "Noticed you're on Shopify Basic and paying a 2% third-party fee" is a real trigger for a payments or checkout offer. Check the facts before you send.
• Trigger on change. Replatforming, a new theme, a new app install or a hiring post for an ecommerce manager all signal budget and attention.
• Lead with an offer, not a pitch. A free store audit, a fee comparison or a migration estimate gets more replies than "can we chat".

Frequently Asked Questions

What is the most used ecommerce platform?

By share of websites in the May 2026 HTTP Archive crawl, WooCommerce leads with 6.64%, followed by Shopify at 4.76%. Share of revenue would give a different ranking, and Shopify is stronger there.

Is Shopify better than WooCommerce?

Neither is better in general. Shopify is hosted and easier to run. WooCommerce gives more control and ownership but needs more maintenance. Pick based on team skills and catalog complexity.

How much does Shopify cost in 2027?

Per its pricing page, plans start at $29 per month on annual billing for Basic, $79 for Grow and $299 for Advanced, with Plus from $2,300 per month. Check the page for current terms.

Which platform is best for a small store?

Shopify Basic, Wix or Squarespace suit most small catalogs. WooCommerce works if you already run WordPress and have someone to maintain it.

Can I sell on Amazon and my own store at the same time?

Yes, and most growing brands do. Use your own store for margin and customer data, and marketplaces for reach.
