How this comparison was built

Scores are medians across 1599 audited core-js sites and 2 audited KISSmetrics 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.

Small sample: one or both technologies have fewer than 10 audited sites. Treat these numbers as directional — medians stabilize around 20–30 audits per side.

Which has better security, core-js or KISSmetrics?
KISSmetrics sites score higher on security analysis (72 vs 65 on average).
Which has better accessibility, core-js or KISSmetrics?
Accessibility scores measured by Lighthouse WCAG 2.1 checks favor KISSmetrics (94 vs 88). 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, core-js or KISSmetrics?
KISSmetrics sites score higher on Lighthouse SEO signals (96 vs 91 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), core-js or KISSmetrics?
core-js sites show lower Time to First Byte (379 ms vs 1003 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.
