How this comparison was built

Scores are medians across 13 audited CentOS sites and 48 audited OpenSSL sites in the BeaverCheck database. Every audit runs the same 100+ checks — Lighthouse performance, security headers, accessibility, SEO, server response time — against a real URL. No vendor input, no sponsorship, no affiliate links.

FAQ

Which is faster, CentOS or OpenSSL?
Based on real BeaverCheck audits, CentOS sites score higher on Lighthouse performance (44 vs 44 on average).
Which has better security, CentOS or OpenSSL?
