OpenGenerativeUI vs agent-ui
Two of the top agent ui and generative ui, side by side: score, setup, license, activity and what each review found.
OpenGenerativeUI
Chat interface that answers with 3D models, charts, calculators and maps

OpenGenerativeUI
Open Intelligent UI is a Next.js chat frontend backed by a Python Deep Agent (FastAPI) that decides per turn whether to reply with text, a native component, or custom HTML/CSS/JS streamed into a sandboxed iframe. A routing model called Jev picks A2UI for basic tables and Open Generative UI for charts, diagrams, calculators and maps. It is built on CopilotKit and AG-UI, with an optional standalone MCP server.
Who it is for: Frontend and agent developers prototyping generative UI chat apps
Strengths
- Generated UI runs in an isolated iframe with a validated host bridge
- Visitors can supply their own OpenAI and Jev keys, held only in browser memory
- Optional MCP server with HTTP, stdio and Docker configuration
- Provider failures are surfaced rather than silently swapped for another model
Weaknesses
- Needs both an OpenAI key and a TYPESAFE_API_KEY for Jev routing
- Requires Node 22+, pnpm 9+, Python 3.12+ and uv locally
- Output format varies per request because the router chooses the renderer
- No tagged release; no compose file
- TypeScript, OpenAI chat-latest, Jev jev-latest
- Needs OpenAI API, Jev (Typesafe) API, USGS map tiles
- Docker
- env example file
agent-ui
A Next.js and shadcn/ui chat interface that connects to a running Agno AgentOS instance (default localhost:7777) and renders streamed replies, tool calls with results, reasoning steps, references and image, video or audio content. Auth is a bearer token set via NEXT_PUBLIC_OS_SECURITY_KEY or the sidebar; the main branch targets Agno v2 and a v1 branch remains. For Agno users who need a frontend without writing one.
Who it is for: Agno users who need a chat frontend
Strengths
- Scaffolds with npx create-agent-ui; endpoint and token editable in the UI
- Renders reasoning steps, references and multimodal outputs, not only text
- Separate branch kept for Agno v1
Weaknesses
- Only speaks to AgentOS; no use outside the Agno stack
- Token is exposed as NEXT_PUBLIC and stored client-side
- No tests, no persistence of its own
- Last commit 2026-05
- TypeScript, agno
- Needs agno-agentos
- GitHub template
