VOSviewer review
A free, focused choice for exploring and presenting bibliometric network relationships.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
VOSviewer is free software for constructing, visualizing, and exploring bibliometric networks. It is designed for researchers, research groups, institutions, and analysts studying publications, journals, researchers, organizations, countries, or terms. Its core work includes citation, co-citation, bibliographic-coupling, co-authorship, and term co-occurrence analyses, making it particularly suitable for mapping relationships across scientific literature rather than managing an entire review workflow.
The published Free plan allows the software to be used freely for any purpose. VOSviewer imports data from Web of Science, Scopus, Dimensions, Lens, and PubMed, and it can query the Crossref, Europe PMC, and OpenAlex APIs. DOI-based networks can also use Semantic Scholar, OpenCitations, and Wikidata APIs. This gives literature analysts several routes for assembling data, while thesaurus files support data cleaning. The software runs across Windows, macOS, and Linux, and VOSviewer Online adds browser-based exploration, sharing, and embedding of interactive visualizations.
Its strongest capability is the depth of its network-visualization toolkit. Users can adjust layout and clustering parameters, switch among network, density, and overlay views, zoom and scroll through maps, label items, and create high-resolution screenshots. That focus suits users who need to identify and communicate patterns in scholarly communication. It is less suitable for teams seeking verified screening or systematic-review management, because those functions are outside its stated scope. Choose VOSviewer for bibliometric mapping and visual analysis; choose another tool when screening and review administration are central requirements.
