Reviews
what people actually sayJetpack Boost is a performance plugin with a mixed reputation — users appreciate its ease of use and LCP improvements, but recurring complaints about site-breaking bugs, negligible real-world speed gains, and server resource overload undermine confidence in its reliability.
