Selenium’s global community of millions is one of the largest in software engineering — the documentation, forums, Stack Overflow coverage, and ecosystem support are unmatched. Sahi Pro’s presence is narrower by design: 1,000 enterprises, with 400 arriving through unprompted referral. Community scale and enterprise reference depth are different assets. For teams evaluating community support as a requirement, Selenium’s ecosystem is larger; for teams that need documented enterprise case studies, Sahi Pro’s are available on request.
