Openalex Vs Scopus: Key Differences & Comparison | CASRAI
OpenAlex and Scopus are both large indexes of the scholarly literature, but they differ fundamentally in model. OpenAlex (from the non-profit OurResearch) is free and fully open with CC0 metadata; Scopus (Elsevier) is a commercial, curated, subscription database.

Common questions
FAQ
Is OpenAlex a replacement for Scopus?+
For many open-analytics and research-information use cases OpenAlex is a viable alternative, since its metadata is free, CC0-licensed, and exposed via an open API. It grew partly as an open successor to the discontinued Microsoft Academic Graph. Whether it fully replaces Scopus depends on your need for curated coverage and the specific tools your institution relies on.
Why does the openness of the metadata matter?+
OpenAlex metadata is released under CC0, so it can be downloaded, reused, and redistributed without licensing restrictions — which supports transparent, reproducible bibliometrics. Scopus data is proprietary and governed by subscription terms, limiting how results can be shared or re-analysed.
Which has broader coverage?+
OpenAlex takes a broad, inclusive approach and indexes a very large number of works and sources, while Scopus applies editorial curation and selective indexing. Broader is not automatically better: inclusiveness aids recall, whereas curation can improve precision and consistency.
