Open-source infinite design canvas where humans and AI agents design together live, with agents joining through a built-in MCP server.

Agent-Native MCP Canvas: Agents connect over an HTTP MCP endpoint with a single command and one browser OAuth approval, then edit the canvas as you, attributed and accountable, with no API keys handed over.
Streaming Frames: Every section an agent writes renders on the canvas the moment it lands, so you watch the design arrive rather than waiting on a spinner.
Comments as Tasks: A note left anywhere on the canvas becomes a task the right agent picks up, works on, and replies to with a screenshot, turning feedback directly into the backlog.
Agent Self-Review: A built-in headless renderer gives agents screenshots of their own frames so they judge fit, spacing and contrast like a senior designer and correct issues before handoff.
Shared Canvas Memory: Tasks, decisions and comments live on the canvas rather than in one agent's context, so any agent that joins later plugs into the same state and continues.
Learned Taste Profile: Casual feedback such as 'rounder corners' or 'keep it to the blue' is distilled into a persistent taste profile applied to every new frame and inherited by every agent.
Live Export URLs: Each frame is a URL that can be embedded in a doc, a post or an og:image and re-renders whenever the design changes, so shared assets never go stale.
Reference and URL Import: Paste screenshots to have agents distill palette, type and mood into a written brief, or paste a public URL to land an editable snapshot of your existing page on the canvas for side-by-side variants.

Agent-Assisted Landing Pages: Steering Claude Code or Codex through hero, pricing and footer frames on one canvas and watching each render live.
Design Review Loops: Leaving contrast or spacing notes on a frame and letting an agent apply the fix and return a screenshot without a synchronous handoff.
Redesign Comparison: Importing an existing public page as an editable snapshot so agent-generated variants sit next to the original instead of replacing it blind.
Team Design Sessions: Multiple people and multiple agents working the same canvas, each seeing what the others' agents are doing in real time.
Style Consistency: Building a canvas taste profile once so every subsequent frame and every new agent inherits the same corner radius, palette and type decisions.
Always-Fresh Shared Assets: Embedding live frame URLs in documentation or social posts so the shared image updates automatically when the design changes.

Rapid Prototyping: Designers and developers can try layout or theme changes on live pages to iterate quickly without modifying source files.
On‑page Bug Fixes: QA engineers or developers can patch visual regressions on a running site by describing the fix and applying a temporary CSS override.
Custom Theming: Power users can restyle web apps or pages for personal preference (dark themes, spacing adjustments) and export styles for persistent use.
Teaching and Learning: Instructors can demonstrate CSS effects by describing desired outcomes and showing the generated code to students.
User Script Creation: Build small user scripts or style overrides that can be exported and re-used across sites or shared with teammates.
Accessibility Adjustments: Quickly apply larger fonts, contrast changes, or spacing improvements to improve readability on-demand.
Rapid prototyping of UI and styling changes without manual CSS coding
Customizing the appearance of third-party websites for personal use or demos
Creating and testing user scripts to modify site behavior or layout
