Stars measure visibility, not whether either tool fits your constraints. ### Are ai-serving and orkhon open source? Yes - both are open-source projects on GitHub (ai-serving: Apache-2.0, orkhon: MIT). ### Where can I find alternatives to ai-serving or orkhon? GraphCanon lists graph-backed alternatives at [ai-serving alternatives](/tools/autodeployai-ai-serving/alternatives) and [orkhon alternatives](/tools/vertexclique-orkhon/alternatives) ([ai-serving markdown twin](/tools/autodeployai-ai-serving/alternatives.md), [orkhon markdown twin](/tools/vertexclique-orkhon/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/autodeployai-ai-serving-vs-vertexclique-orkhon.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, ai-serving or orkhon? ai-serving: Slowing. orkhon: Dormant. 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 ai-serving and orkhon? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [ai-serving trust report](/tools/autodeployai-ai-serving/trust); [orkhon trust report](/tools/vertexclique-orkhon/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=autodeployai-ai-serving`](/api/graphcanon/graph?tool=autodeployai-ai-serving) - 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/_
