JournalIndexing is an independent, non-commercial reference tool for exploring and comparing academic journal metrics. Its database brings together information from Web of Science, Scopus and SCImago, with OpenAlex data included where available. Users can search thousands of peer-reviewed journals and review measures such as Impact Factor, Journal Citation Indicator quartiles, SCImago Journal Rank (SJR), H-index and citation-related metrics.

The site offers filters for indexing database, citation index, quartile, subject category, country or region, open-access status, score ranges and journal activity. Visitors can browse journal rankings, compare titles, view journal details and analytics, and explore publishing patterns by discipline and geography. Additional sections highlight journals by field and rank them using impact scores, H-index and other citation measures.

JournalIndexing is intended as a discovery and comparison resource for researchers, authors and readers. It advises users to verify current journal information, indexing status, publication policies and submission details with each journal’s official website before making decisions.
