Builder

Visual headless CMS for marketing pages with component-driven content and A/B testing.

Overview

Builder.io is a collaborative platform that unifies code development, design, and content creation in a single source of truth. It combines two core products—Fusion for app and UI development, and Publish for content management—enabling engineers, designers, product managers, and marketers to work together without handoffs.

The platform features AI agents that accelerate development workflows, a visual editor wired directly to production code and design systems, and integrations with popular frameworks and tools. Teams can generate working prototypes, build new features, and publish campaigns while maintaining brand consistency and code quality throughout the process.
