Fusion

Builder.io visual canvas with Figma-to-code and code-to-Figma sync

freemiumupdated Apr 21, 2026

Fusion by Builder.io is a visual development canvas that provides bidirectional sync between Figma designs and production code. Designers edit in Figma while developers work in code, and changes propagate in both directions. Supports React, Vue, Svelte, Angular, and Qwik output with a visual editor for non-developers to make content and layout changes without touching code.

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.

Uizard logo

Uizard

Editable UI flows from prompts, screenshots and sketches

AI-assisted product-design platform that turns prompts, screenshots and hand-drawn sketches into editable UI flows for non-designers and early product ideation, complementing rather than duplicating developer-first code generators.

Magic Patterns

Design-system-aware AI prototyping for code-ready product interfaces

Magic Patterns turns product ideas, prompts, screenshots, and existing UI into editable, code-ready interfaces. Its design-system-aware editor supports collaborative iteration, two-way GitHub sync, and an MCP workflow for moving designs between the canvas and coding agents—positioning it between prompt-to-app builders and design-handoff tools rather than as a single-screen generator.

Mitosis

Write components once and compile them into native code for multiple frameworks

Mitosis is Builder.io-backed open-source infrastructure for writing a component once and compiling it into native framework components for React, Vue, Angular, Svelte, Qwik, Solid, React Native, and other targets. It supports cross-framework design systems and Figma-to-code synchronization, but is distinct from the Builder.io visual builder product.

Figma Console MCP

Turn a Figma design system into a programmable API for AI assistants

Figma Console MCP is open-source design-system infrastructure that exposes Figma to AI assistants through MCP. It supports structured extraction, design creation and editing, debugging, accessibility audits, and bidirectional design-token workflows across local, remote read-only, and paired cloud modes; it is not a generic one-click Figma-to-code exporter.

OpenUI

Open-source UI generation from natural-language prompts

OpenUI is an Apache-2.0 design-to-code tool from W&B that turns natural-language interface prompts into live HTML previews and frontend code. Teams can run it locally or with Docker, connect OpenAI, Groq, LiteLLM-compatible providers, or Ollama, and export generated UI toward React, Svelte, Web Components, and related workflows. It fits rapid UI mockups where developers want editable code instead of screenshots.

Figma MCP Server

Official remote MCP server for design-to-code and write-to-canvas Figma workflows.

Figma MCP Server is Figma’s official remote Model Context Protocol surface for design-to-code agents. It gives supported clients structured design context, variables, components, selected-frame code context, Code Connect mappings, and beta write-to-canvas tools for creating or updating native Figma frames from an MCP client while keeping the workflow tied to Figma files.
