Cheap and basic. We are higher up the stack.
WP Fastest Cache is a low cost basic cache plugin. It is fine for blogs and brochure sites that just need a sprinkle of caching. It is the wrong tool for an agency operating at scale. Honest comparison.

Where WP Fastest Cache wins
Free. Simple. Sets up in two minutes. For a single blog or marketing site that needs nothing fancier, it does the job. The premium version adds image conversion and minor extras at $40 a year.
Where it stops
It is a cache plugin. It does not generate critical CSS, does not remove unused styles, has no JS interaction delay, no audit history, no fleet view, no alerts. Once your site needs more, you have to add other plugins to fill the gaps.
Where HBM Rocket replaces it
Everything WP Fastest Cache does plus the entire optimization pipeline plus continuous monitoring. Migrate when your scores plateau in the 70s or you start managing more than two sites.
