Other tools check your server. KernelWP checks your server, your WordPress layer, your cache stack, your real-world vitals, your security posture, and your network — then tells you exactly what to fix.
CPU, memory, disk I/O, PHP version, OPcache status, MySQL throughput, and TTFB — the raw infrastructure under your site.
Query count, autoloaded options, active cron jobs, REST API latency, theme and plugin overhead — the WP-specific bottlenecks.
Object cache detection (Redis, Memcached), page cache verification, transient audit, and cache hit-rate analysis.
LCP, CLS, INP, FCP — the metrics Google actually ranks you on. Measured with real rendering, not just server timing.
Exposed debug logs, file permissions, SSL configuration, outdated software, and security headers — the gaps attackers find first.
HTTP/2 & HTTP/3 support, CDN detection, DNS response time, TLS handshake overhead, and third-party script impact.
Each module produces a weighted sub-score. KernelWP combines them into a single 0–100 grade your team and clients can rally around — with full drill-down when you need it.
Full WP-CLI integration with --porcelain output for GitHub Actions, GitLab CI, and any automation workflow. Set score thresholds, export JSON history, and generate PDF reports — all without opening a browser.
