[OpenRath](https://www.openrath.com/) reports 1.1k GitHub stars, 52 forks, and 4 open issues, last pushed Jul 22, 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 [OpenRath's repository](https://github.com/Rath-Team/OpenRath) and [agent-kernel's repository](https://github.com/yaalalabs/agent-kernel). | | [OpenRath](/tools/rath-team-openrath.md) | [agent-kernel](/tools/yaalalabs-agent-kernel.md) | | --- | --- | --- | | Tagline | An open-source runtime for dynamic multi-agent workflows | The Operating System for Scalable Enterprise AI Agents | | Stars | 1,100 | 113 | | Forks | 52 | 60 | | Open issues | 4 | 128 | | Language | Python | Python | | Adopt for | OpenRath highlights its unique capabilities in managing multi-agent workflows dynamically, offering an open-source runtime with Python integration that rivals PyTorch but focuses on AI agents and their sessions. | 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 | BSD-3-Clause | Apache-2.0 | | Categories | AI Agents, Data & Retrieval | AI Agents | ## Trust and health _Sourced signals - not a safety guarantee.

If you are working on single-agent tasks with limited or no need for interaction between agents, OpenRath's capabilities may be overkill. When your focus is exclusively on model training rather than runtime workflows and interactions, other libraries or frameworks might offer more direct support. ### When should I avoid agent-kernel? If your project is confined to a single, specific AI framework which doesn't require the flexibility Agent-kernel offers. When you do not have Python version 3.12 - 3.13.x, as it's the required runtime environment. ### Is OpenRath or agent-kernel more popular on GitHub? OpenRath has more GitHub stars (1,100 vs 113). Stars measure visibility, not whether either tool fits your constraints. ### Are OpenRath and agent-kernel open source? Yes - both are open-source projects on GitHub (OpenRath: BSD-3-Clause, agent-kernel: Apache-2.0). ### Where can I find alternatives to OpenRath or agent-kernel? GraphCanon lists graph-backed alternatives at [OpenRath alternatives](/tools/rath-team-openrath/alternatives) and [agent-kernel alternatives](/tools/yaalalabs-agent-kernel/alternatives) ([OpenRath markdown twin](/tools/rath-team-openrath/alternatives.md), [agent-kernel markdown twin](/tools/yaalalabs-agent-kernel/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/rath-team-openrath-vs-yaalalabs-agent-kernel.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, OpenRath or agent-kernel? OpenRath: Very active. agent-kernel: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for OpenRath and agent-kernel? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [OpenRath trust report](/tools/rath-team-openrath/trust); [agent-kernel trust report](/tools/yaalalabs-agent-kernel/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=rath-team-openrath`](/api/graphcanon/graph?tool=rath-team-openrath) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
