CitNetExplorer review
A free, research-focused desktop tool for exploring large Web of Science citation networks.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CitNetExplorer is a Windows desktop application for visualizing and analyzing citation networks of scientific publications. It is aimed at researchers and teachers studying how research fields develop, finding literature on a topic, examining a researcher's publication oeuvre, or supporting a literature review. Its scope is specialized: the starting point is a publication citation network, rather than a general-purpose graph visualization workflow.
A notable strength is its ability to work with very large networks, including millions of publications and tens of millions of citation relations. Users can zoom and scroll with automatic label placement, inspect indirect citation relations, and navigate by drilling down or expanding from selected publications, with back and forward controls. Publication selection can focus on the oldest or most recent publications. Analysis options include connected components, clusters, core publications, and shortest or longest paths. Together, these functions make it suited to exploring structure and development within a research corpus, not just viewing a static network.
The published license makes CitNetExplorer freely available for non-commercial research and teaching, so its fit depends on the intended use. Direct Web of Science import and Pajek-format export shape its ecosystem: it can bring in data from Web of Science and send citation networks out in that format. Windows-only availability is a constraint for researchers who need another desktop platform, while the research-and-teaching license rules out commercial use. Choose it for large scientific citation-network exploration within those boundaries; consider a different tool if you need commercial licensing, broader graph use, or another operating system.
