Fusion represents Builder.io's vision of eliminating the handoff gap between design and development by making Figma and code two views of the same source of truth. When a designer modifies a component in Figma, the change can propagate to the production codebase. When a developer modifies the code, the Figma design file updates to reflect the change. This bidirectional sync eliminates the design drift that accumulates when designs and code are maintained independently.
The visual canvas provides a WYSIWYG editing experience where content creators, marketers, and product managers can modify page layouts, text content, images, and component configurations without opening a code editor. Changes made in the visual canvas produce clean code output in the project's framework of choice. Support for React, Vue, Svelte, Angular, and Qwik means the visual editing capability works regardless of the team's technology stack.
Fusion integrates with Builder.io's headless visual CMS, enabling organizations to give non-technical team members the ability to create and modify web pages while developers maintain control over the component system and design constraints. The component-based architecture means visual editors compose pages from developer-defined building blocks, ensuring visual changes stay within the boundaries of the design system.
