Webflow CMS is Webflow's integrated content management system for building dynamic, data-driven websites — enabling teams to define custom content types (Collections) and have editors add content through a structured interface while developers control the visual presentation. Unlike headless CMS platforms, Webflow CMS is tightly coupled to the Webflow visual editor, meaning the data and the design live in the same system. It powers dynamic blogs, portfolio galleries, job boards, and event listings on Webflow sites. CMS-powered Webflow pages are identifiable through w-dyn-item class names on individual collection items and w-dyn-list on collection list containers — these are injected by Webflow's CMS rendering engine and appear consistently across all CMS-powered Webflow sites.
