[ag-ui](https://ag-ui.com) reports 15k GitHub stars, 1.4k forks, and 343 open issues, last pushed Aug 19, 2026. [openagent](https://openllm.cloud) has 792 stars, 80 forks, and 46 open issues, last pushed Jul 17, 2026. Figures are from public GitHub metadata via [ag-ui's repository](https://github.com/ag-ui-protocol/ag-ui) and [openagent's repository](https://github.com/Haohao-end/openagent). | | [ag-ui](/tools/ag-ui-protocol-ag-ui.md) | [openagent](/tools/haohao-end-openagent.md) | | --- | --- | --- | | Tagline | Agent-User Interaction Protocol for Frontend Applications | Harness architecture for rapidly building vertical AI agents | | Stars | 15,412 | 792 | | Forks | 1,389 | 80 | | Open issues | 343 | 46 | | Language | Python | Python | | Adopt for | Ag-UI specializes in integrating AI agents into frontend applications using TypeScript, providing a protocol for agent-user interaction. | OpenAgent integrates OpenAI and Dify, focusing on deep reasoning loops, visual workflows, RAG, and agent delegation in Python under MIT license. | | Persona | - | - | | Runtime | - | - | | License | Ag-UI is licensed under MIT, allowing for open-source usage with contributions being openly permitted and encouraged. | MIT | | Categories | AI Agents, Developer Tools | AI Agents, Data & Retrieval, Vector Databases | ## Trust and health _Sourced signals - not a safety guarantee.
