Introducing Fusion: Vibe Code at Any Scale

June 18, 2025

Written By Steve Sewell

What if your whole team could vibe code with your actual stuff... through a visual canvas?

Your components, your design systems, your APIs—all accessible so you can just prompt away in a browser or your IDE.

Current AI coding tools make you choose: either they're powerful enough for real work but only developers can use them, or they're accessible to your whole team but fall apart the moment you need to integrate with actual existing codebases.

Today, we're launching Fusion—the first AI-powered visual canvas that integrates directly with your existing codebase, design system, and workflows.

With Fusion, your entire team, from designers to developers to PMs, can quickly generate, iterate, and ship products at any scale.

We're live on Product Hunt today! We'd love your support.

Fusion - Vibe code at any scale | Product Hunt

Built for real-world use

Fusion handles complex enterprise workflows but still feels as intuitive as the best vibe coding tools because we built it with real teams. We worked directly with our enterprise customers and gathered insights from over 23,000 designers and developers to make sure it works at any scale.

Existing codebase integration

Connect to any GitHub repository and start building immediately—prompt your changes in plain English and watch them happen visually. Connect multiple repositories locally using the CLI for complex, multi-repo projects. Fusion creates branches for your changes and generates preview URLs for every PR.

Design systems, API intelligence and workspaces

Fusion indexes your code components and understands your design system patterns. Whether you're describing a feature in natural language or importing designs straight from Figma, it knows your components, tokens, and patterns well enough to generate pixel-perfect code that actually follows your design system.

Fusion also automatically discovers and integrates with your internal APIs to connect to your existing services and data sources. For larger teams and complex architectures, create workspaces to connect multiple repositories and give the AI visibility across your entire codebase ecosystem.

Visual editing with code precision

Edit your code components, CSS, and layouts as visually as you would in Figma, but with the precision and power of code. Your changes are live in your actual codebase, so you see exactly how they look.

Agentic pull requests workflow

Our AI keeps working even when you close your browser, doing way more than just generating code. Create a PR, tag @builder-bot in your comments, and watch as the AI responds to feedback, fixes build failures, and iterates on changes automatically.

Rich Figma integration

Copy and paste single designs, combine multiple Figma screens into one component (like a carousel), or use designs as context to update existing elements. Ask the AI to match specific design tokens, spacing, or styling from your Figma files. Everything maps properly to your existing design system.

Multi-format context support

Import your Figma designs, attach PDFs with requirements, upload reference images, or share mockups. Fusion understands all types of visual context to build exactly what you need.

VS Code integration

The VS Code plugin brings Fusion's full power directly into your local development environment—pull in Figma designs, generate components using your design systems, and access AI-powered editing without switching contexts. All of Fusion's visual development capabilities now fit perfectly into the workflow you already know and love.

Universal integrations via MCP

Connect Fusion to any tool with an MCP server.

Permissions and access control

Set granular permissions to control what each team member can edit. Scope designers to only edit specific file paths or patterns, restrict access to sensitive directories, and define role-based editing permissions across your entire codebase. Enterprise-grade guardrails ensure the right people can edit the right parts of your application.

Built for whole team collaboration

For designers: Finally see your vision live

You no longer need to wonder if your design will look right in production. Import your Figma designs directly into the codebase and watch them become functional components. When something looks off, edit it visually until it's pixel-perfect. You control exactly how your design looks in the live application because you're no longer leaving it to interpretation.

Perfect for: Ensuring design consistency, validating responsive designs, and eliminating the endless "that's not quite right" feedback cycles.

For developers: AI-powered UI creation

You know the scenario: design teams have overwhelming request queues, but you need to ship that form, dashboard, or admin interface. Instead of struggling with layout decisions, describe what you need in plain English. Fusion generates clean, consistent UIs using your existing design system patterns, so you can focus on the logic while the AI handles the visual implementation.

Perfect for: Internal tools, rapid prototyping, and any time you need to create interfaces without dedicated design resources.

For product managers: Ship changes today, not next sprint

You don't need to wait for the next development cycle to ship that "simple" button change or dashboard tweak. Make the change yourself using natural language prompts or visual editing, create a PR, and let the team review. You contribute directly to the codebase without creating bottlenecks.

Perfect for: Quick iterations, A/B testing different layouts, and keeping momentum on product improvements.

For design system teams: Enforce patterns, not just components

Your design system becomes truly intelligent. Instead of providing components that teams often misuse, Fusion learns your patterns and enforces them automatically. The AI understands not just what components to use, but how to use them correctly in different contexts.

Perfect for: Maintaining consistency across large teams, onboarding new developers, and ensuring design system adoption at scale.

Getting started

You can start with Fusion in two ways:

Connect your existing repository

Have a GitHub repo you're already working on? Connect it to Fusion and start editing your components visually right away. Whether it's a React, Next.js, Svelte, Vue, or Angular project, Fusion integrates with your existing codebase. Create a branch, make your changes, and see them live instantly.

Start fresh with an idea

Don't have a project yet? No problem. Start with a simple prompt like "Create a contact form with validation" or "Build a pricing table with three tiers.” Fusion will generate everything from scratch using your preferred framework and design systems, giving you a complete starting point to build upon.
