Archon has more GitHub stars (23,505 vs 3,788). Stars measure visibility, not whether either tool fits your constraints. ### Are Archon and aiac open source? Yes - both are open-source projects on GitHub (Archon: MIT, aiac: Apache-2.0). ### Where can I find alternatives to Archon or aiac? GraphCanon lists graph-backed alternatives at [Archon alternatives](/tools/coleam00-archon/alternatives) and [aiac alternatives](/tools/gofireflyio-aiac/alternatives) ([Archon markdown twin](/tools/coleam00-archon/alternatives.md), [aiac markdown twin](/tools/gofireflyio-aiac/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/coleam00-archon-vs-gofireflyio-aiac.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, Archon or aiac? Archon: Very active. aiac: Slowing. 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 Archon and aiac? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [Archon trust report](/tools/coleam00-archon/trust); [aiac trust report](/tools/gofireflyio-aiac/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=coleam00-archon`](/api/graphcanon/graph?tool=coleam00-archon) - 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/_
