Framer is a powerful, no-code platform for designing, building, and publishing interactive and responsive websites, bridging the gap between design and development by letting designers create production-ready sites visually, similar to Figma but for the web, with features like built-in CMS, AI tools, and seamless hosting. It offers a canvas-based interface for visual design, animation, and prototyping, making it a modern alternative to traditional website builders for professional site creation.
