How this comparison was built

Scores are medians across 12 audited CentOS sites and 47 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 (48 vs 45 on average).
Which has better security, CentOS or OpenSSL?
OpenSSL sites score higher on security analysis (64 vs 60 on average).
Which has better accessibility, CentOS or OpenSSL?
Accessibility scores measured by Lighthouse WCAG 2.1 checks favor CentOS (89 vs 86). Both technologies can be made fully accessible with care — the difference reflects common patterns in the sampled sites, not inherent platform limits.
Which is better for SEO, CentOS or OpenSSL?
CentOS sites score higher on Lighthouse SEO signals (92 vs 90 on average), which cover meta tags, crawlability, mobile friendliness, and structured data. Content strategy and backlinks still matter more than platform choice for ranking.
Which has faster server response (TTFB), CentOS or OpenSSL?
OpenSSL sites show lower Time to First Byte (512 ms vs 1543 ms on average). TTFB depends heavily on hosting and CDN setup rather than the technology itself, but the sampled sites suggest a meaningful difference in common deployment patterns.
Should I choose CentOS or OpenSSL for my website?
