Open Generative UI

this is a good signal that `agent UX` is shifting from text-plus-tools toward runtime-generated interfaces, with skills/specs becoming the control layer over unconstrained visual output.

  • Extracted main post via api.fxtwitter.com fallback and checked the linked repos/docs for CopilotKit/generative-ui and CopilotKit/OpenGenerativeUI.
  • Akshay Pachaar highlights Open Generative UI, an open-source take on Claude-style artifacts: the agent streams HTML/SVG token-by-token into a sandboxed iframe so the UI visibly assembles live in chat.
  • The interesting implementation choice is that this is not component selection but open-ended UI generation from scratch, with safety coming from iframe isolation and quality steered by skill/prompt layers.
  • Repo framing broadens it beyond one demo: CopilotKit positions generative UI as three patterns (controlled, declarative, open-ended) across AG-UI, A2UI/Open-JSON-UI, and MCP Apps, with OpenGenerativeUI as the high-freedom showcase.
  • Why it matters: this is a good signal that agent UX is shifting from text-plus-tools toward runtime-generated interfaces, with skills/specs becoming the control layer over unconstrained visual output.
  • Good angle: artifacts are escaping proprietary chat apps and turning into an open protocol/framework battle around agent-native UI.
