[agent-framework](https://aka.ms/agent-framework) reports 14k GitHub stars, 2.3k forks, and 605 open issues, last pushed Sep 18, 2026. [1flowbase](https://1flowbase.taichuy.com/) has 261 stars, 20 forks, and 17 open issues, last pushed Sep 10, 2026. Figures are from public GitHub metadata via [agent-framework's repository](https://github.com/microsoft/agent-framework) and [1flowbase's repository](https://github.com/taichuy/1flowbase). | | [agent-framework](/tools/microsoft-agent-framework.md) | [1flowbase](/tools/taichuy-1flowbase.md) | | --- | --- | --- | | Tagline | Framework for building and deploying AI agents and multi-agent workflows | Open-source AI gateway for local agent clients | | Stars | 13,573 | 261 | | Forks | 2,335 | 20 | | Open issues | 605 | 17 | | Language | Python | Rust | | Adopt for | The agent-framework provides tools for developers to build and deploy AI agents and multi-agent workflows in Python and .NET environments. | Open-source AI gateway in Rust for managing local multi-model workflows with detailed observability | | Persona | - | - | | Runtime | - | - | | License | MIT | Apache-2.0 | | Categories | AI Agents, Developer Tools | AI Agents, Evaluation & Observability, Inference & Serving | ## Trust and health _Sourced signals - not a safety guarantee.
