Reviews
what people actually sayComet Cache is a well-regarded caching plugin praised for ease of use and genuine speed improvements, but its reputation is seriously undermined by apparent abandonment — no meaningful updates since 2017, no support even for paid customers, and at least one report of malicious files being introduced after an update.
What people like
- +Delivers noticeable, real-world page speed improvements, often outperforming other caching plugins on the same site×7
- +Easy to set up and activate with minimal configuration needed×5
- +Works on sites where other caching plugins fail or cause slowdowns×3
- +Supports caching differentiated by logged-in vs. logged-out users, useful for membership sites
- +Works without requiring pretty permalinks, unlike most competing plugins
- +Pro version offers additional capability on top of an already functional free product×2
Common complaints
- −Project appears abandoned — no meaningful updates since 2017, raising serious long-term reliability and security concerns (since 170220)×5
- −No support provided, even for paying Pro customers — no responses to tickets or forum posts for extended periods×3
- −At least one user reported malicious/infected files appearing on their sites after a plugin update
- −Compatibility issues with other plugins (e.g. MonsterInsights Pro, blog2social)
- −Intermittent visible text errors on the front end requiring a cache flush to resolve
- −Free version lacks browser caching leverage; settings UI is verbose and confusing
- −Pro version purchase considered a waste of money given the lack of updates and support×2
