Webflow and Framer are both visual website builders with full design control and a CMS. Webflow is known for deep, granular CSS control and a large marketplace/ecosystem, at the cost of a steeper learning curve. Framer is known for a design-tool-native feel with faster time-to-polish and best-in-class animation/interaction defaults. Neither is objectively "better." The right pick depends on what you're optimizing for.
Choose Webflow if you are building a complex site and want maximum control plus a mature plugin ecosystem. Choose Framer if you are a designer who wants to move fast and ship best-in-class motion and interactions.
