Design with real code
Create UI with real HTML, CSS, and React rather than an abstract design layer, so the output matches what ships.
Lunagraph
Lunagraph is a design canvas for building UI with real HTML, CSS, and React code, powered by Claude Code. It is aimed at designers, product teams, and developers who want design and implementation to stay in sync.
Overview
Lunagraph is a design canvas that writes real HTML, CSS, and React code, powered by Claude Code. It is positioned as a place where design and implementation happen together instead of through a handoff step.
The product is built for teams that want the canvas, the chat, and the codebase to stay in sync. The source describes a workflow where designers, product people, developers, and agents can shape UI directly, preview changes in a live iframe, and compare the canvas with the implementation before shipping.
Key features
AI-assisted canvas editing
Claude Code works inside the canvas to generate and edit code as you design, with the product presented as "powered by Claude Code."
Round-trip editing
Keep the canvas and codebase aligned by editing in either place and letting changes sync in both directions.
Zero-handoff workflow
Work from the same source of truth across designers, product, developers, and agents to reduce translation between design and implementation.
Website-to-canvas capture
Use a Chrome extension to copy UI from any website and paste it into Lunagraph as a starting point.
Desktop canvas workspace
Start from the desktop app and work with pages, sidebar navigation, chat, layers, insert tools, assets, and icons as part of the canvas workflow.
Use cases
Designing UI that ships as code
Designers can work directly on the final code structure instead of handing off static mockups and waiting for implementation to catch up.
Collaborative product iteration
Product and engineering teams can use the shared canvas and codebase to keep implementation aligned with design changes.
Component refactoring with visual feedback
Developers can break apart or refine components in code while keeping the canvas representation in sync through round-trip editing.
Importing web UI as a reference
Teams can capture an existing website UI with the Chrome extension and use it as a starting point for further edits in Lunagraph.
Previewing and comparing changes
People exploring layout or styling changes can preview updates in a live iframe and compare the canvas with the rendered result before approving work.
