Show HN: Doop – open-source live canvas for AI agents to design (github.com)

Doop has launched as a groundbreaking open-source alternative to Paper.design, facilitating a collaborative design environment for both human users and AI agents. This multiplayer canvas allows users to create and manipulate designs in real-time, with every interaction visible to all participants, including edits made by connected AI agents via a built-in MCP server. This innovative framework not only promotes seamless cooperation among users but also enhances how AI can contribute to design processes, moving beyond traditional prompt-and-refresh methods to interactive, live design streaming. For the AI and machine learning community, Doop is significant as it demonstrates a robust application of AI in creative design, enabling agents to autonomously sketch and refine designs on shared canvases. Technical features include real-time updates through WebSockets, design memory for maintaining stylistic consistency, and a simple one-command setup for self-hosting. Additionally, the platform integrates smoothly with AI models like Claude Code, allowing agents to operate under user-defined parameters while inheriting access controls. Such capabilities underscore the evolving role of AI in collaborative tasks, paving the way for future advancements in shared creative processes.
