See the comparison table for live GitHub stats and shared categories. ### When should I choose evidently over viewer? Choose evidently over viewer when evidently is primarily Jupyter Notebook; viewer is Python; Tags unique to evidently: data-drift, data-quality, data-validation, gen-ai; Integrating into projects using Jupyter Notebooks where detailed observability is needed. ### When should I choose viewer over evidently? Choose viewer over evidently when viewer is primarily Python; evidently is Jupyter Notebook; Tags unique to viewer: 3d, exploration, files, free software; Also covers Developer Tools; You require a detailed, 3D visualization of model structures and tensor data. ### When should I avoid evidently? For developers preferring non-Jupyter based development environments Projects needing fewer, simpler monitoring tools without extensive metric support ### When should I avoid viewer? Your workflow necessitates non-interactive visualization methods. The viewer's license ambiguity could pose risks to proprietary projects or sensitive data handling. ### Is evidently or viewer more popular on GitHub? evidently has more GitHub stars (7,790 vs 1,835). Stars measure visibility, not whether either tool fits your constraints. ### Are evidently and viewer open source? Yes - both are open-source projects on GitHub. ### Where can I find alternatives to evidently or viewer? GraphCanon lists graph-backed alternatives at [evidently alternatives](/tools/evidentlyai-evidently/alternatives) and [viewer alternatives](/tools/zetane-viewer/alternatives) ([evidently markdown twin](/tools/evidentlyai-evidently/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/evidentlyai-evidently-vs-zetane-viewer.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, evidently or viewer? evidently: Very active. 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 evidently and viewer? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [evidently trust report](/tools/evidentlyai-evidently/trust); [viewer trust report](/tools/zetane-viewer/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=evidentlyai-evidently`](/api/graphcanon/graph?tool=evidentlyai-evidently) - 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/_
