Woocommerce is everywhere. Absolutely everywhere. Over four million stores.
About a third of all non-big-box/amazon online shopping runs through Woocommerce installations. Much more than Shopify, which is the next biggest.
Because it’s a plugin for WP you might not ever notice a store is Woocommerce until you get the store emails that people often don’t customise much.
It’s fully possible to run a Woocommerce store without giving anyone a cut beyond your payment provider’s normal cut.
It’s not too difficult to extend; custom payment gateways and order processing hooks, inbound APIs, GraphQL etc.
If you are judicious about your install — just run Woocommerce, WP, customise one of the core themes or a well-known good theme like WP-Start or an Anders Noren theme, use the Stripe or Paypal payment gateway, it’s pretty solidly secure, too; you’ll get automatic updates.
It’s not the most fun thing to administer, but it’s not Magento at least.
Automattic’s acquisition of Woocommerce was a blessing; some of the more complex extensions to woocommerce are still paid addons, which is where they make their money (as well as payment gateway referral fees, which was a little-noticed part of the squabble with WP Engine, who modified woocommerce to change the referrer to point to them). Woothemes were unpredictable and at times rapacious.
