How we compare

How does GraphCanon compare AI development tools?: Each compare page pits two published tools side by side with live GitHub stats, shared categories, typed graph relationships, and optional trust signals. We surface constraints and data, not a single winner score.
Are GraphCanon comparisons neutral?: Yes. Stats come from GitHub and our ingest pipeline; relationship types are typed in the graph. Marketing copy and README excerpts are labeled as repository-derived data, not endorsements.
Where do comparison pages come from?: Featured pairs are curated for high-intent searches (frameworks, vector DBs, agent runtimes). Additional URLs are generated from alternative and successor edges between published tools in the knowledge graph.
