[Kiln](https://kiln.tech) reports 5.0k GitHub stars, 375 forks, and 69 open issues, last pushed Aug 23, 2026. [agent-kernel](https://kernel.yaala.ai/) has 113 stars, 60 forks, and 128 open issues, last pushed Aug 7, 2026. Figures are from public GitHub metadata via [Kiln's repository](https://github.com/Kiln-AI/Kiln) and [agent-kernel's repository](https://github.com/yaalalabs/agent-kernel). | | [Kiln](/tools/kiln-ai-kiln.md) | [agent-kernel](/tools/yaalalabs-agent-kernel.md) | | --- | --- | --- | | Tagline | Build, Evaluate, and Optimize AI Systems | The Operating System for Scalable Enterprise AI Agents | | Stars | 5,034 | 113 | | Forks | 375 | 60 | | Open issues | 69 | 128 | | Language | Python | Python | | Adopt for | Kiln is a versatile AI systems development toolkit that excels in comprehensive evaluation frameworks for agents, RAG components, and fine-tuning processes. | Agent-kernel provides an operating system for scalable enterprise AI agents, supporting deployment and orchestration at scale with native integration support for MCP and A2A. | | Persona | - | - | | Runtime | - | - | | License | Other | Apache-2.0 | | Categories | AI Agents, Data & Retrieval, Evaluation & Observability, Model Training | AI Agents | ## Trust and health _Sourced signals - not a safety guarantee.
