Code-aware generation
Create apps, features, prototypes, and UI using your repo, components, patterns, and project rules as context.
Fusion
Build in your existing codebase
Create apps, features, and prototypes with your team, design system, and AI tools.
Start from your repo
Connect your design system and APIs so every change fits your stack instead of living in a disconnected sandbox.
Build with your AI tools
Begin from a prompt, a Figma design, or a branch from Claude Code, Cursor, or Codex, then keep going in Fusion instead of starting over.
Collaborate on the same branch
Designers refine UI, marketers edit copy, and PMs leave feedback, all on the same code your engineers ship.
Ship through approved PRs
Approved changes become pull requests and move through your trusted pipeline. Behind a firewall, Builder connects to internal Git, registries, and APIs over a private link.
Key Features
Everything product teams need to build in real code
Visual code editing
Edit layout, spacing, styling, and copy visually while each change updates the underlying code.
Figma plugin
Import Figma designs and turn them into responsive UI using your components and design system.
Design system intelligence
Use your components, tokens, and usage patterns so new UI follows the system your team already ships with.
Branch and PR workflow
Package work into branches and pull requests so your team can review changes, leave feedback, and merge through your existing process.
Builder MCP
Push branches from Cursor, Claude Code, or Codex into Builder for team polish, then pull them back when they are ready for engineering review.
Fusion Integrations
Connect Fusion to the stack your product team already uses
Frontend frameworks
Run Fusion with the frameworks your product already ships on, including React, Next.js, Vue, Svelte, and Angular.
Source control and review
Connect GitHub, GitLab, Bitbucket, or Azure DevOps so work moves through your existing branch and pull request process.
Shared development environments
Move work between Cursor, Claude Code, Codex, and Fusion so engineers can keep coding while the broader team polishes, tests, and reviews in Builder.
Extend with MCP connectors
Connect Builder to the other tools, data sources, and shared workflows your team depends on.
Use Cases
Accelerate your entire software development lifecycle
