FlyingPress wins on simplicity. Toggle the right options, the cache fills, the preload runs, and the front end ships an optimized page. The default admin reports a global percentage and the most recent issue but stops short of letting anyone read the queue. A handful of templates can fail critical CSS generation, the preload can stall on specific URLs, and the global stats card still looks healthy.

SleekView Charts reads fp_* postmeta and the flying_press_settings option and renders dashboard cards over the same per-URL data. A Number card carries the count of URLs cached today, a Donut splits critical CSS state across OK, Pending, and Missing, a Bar surfaces preload failures by post type, and an Area chart traces daily refresh activity so a deploy that did not regenerate the cache shows as a flat line.

Charts are read-only against the cache directory and route inline purge actions through the plugin's own functions. The cache itself stays in FlyingPress's hands; SleekView Charts just gives the team responsible for performance a dashboard to read.

FlyingPress earns its reputation by getting out of the way. The toggles fill the cache, the preload runs, and the optimized HTML ships. The opacity shows up when a few templates quietly fail critical CSS while the global stats card still looks fine, and the only honest way to spot the regression is to run a SQL query or open postmeta by hand.

The data is already there. Charts just render it as the dashboard the default admin never built, and the cache keeps doing exactly what it did before.
