Ecommerce platforms split mainly by who runs the servers. Hosted services such as Shopify and BigCommerce handle hosting and checkout, while open-source platforms such as WooCommerce, PrestaShop and OpenCart run on a server the owner controls. Headless systems suit developers building their own storefront.
Form builders differ in where responses are stored, whether they take payments and how much logic they support.

Scheduling tools differ mainly in how they handle team routing, paid bookings and hosting. Calendly and Acuity suit client-facing businesses, SavvyCal and TidyCal suit individuals who want lightweight links, and Cal.com is the open-source option that can be self-hosted.
