The viewer's license ambiguity could pose risks to proprietary projects or sensitive data handling. ### Is manifold or viewer more popular on GitHub? viewer has more GitHub stars (1,844 vs 1,673). Stars measure visibility, not whether either tool fits your constraints. ### Are manifold and viewer open source? Yes - both are open-source projects on GitHub. ### Where can I find alternatives to manifold or viewer? GraphCanon lists graph-backed alternatives at [manifold alternatives](/tools/uber-manifold/alternatives) and [viewer alternatives](/tools/zetane-viewer/alternatives) ([manifold markdown twin](/tools/uber-manifold/alternatives.md), [viewer markdown twin](/tools/zetane-viewer/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/uber-manifold-vs-zetane-viewer.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, manifold or viewer? manifold: Dormant. viewer: 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 manifold and viewer? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [manifold trust report](/tools/uber-manifold/trust); [viewer trust report](/tools/zetane-viewer/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=uber-manifold`](/api/graphcanon/graph?tool=uber-manifold) - 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/_
