The problem
Shoppers used Fakespot to judge whether a product's reviews looked trustworthy, and it has shut down. Store-generated summaries describe what reviewers say but not how the reviews arrived. Buyers want a quick look at rating trends and sudden bursts of reviews before they buy, without a black-box verdict.
For: Online shoppers · Former Fakespot users · Deal hunters
Why now
Mozilla shut down Fakespot's extensions, apps and website on July 1, 2025, and the FTC's rule banning fake reviews and testimonials took effect on October 21, 2024.
Demand signals
Monthly Google searches in the US, pulled 2026-09-24. These are the words people with this problem actually type.
Searches for a Fakespot replacement are fading since it closed: “fakespot alternative” fell to about 520 a month in summer 2026. “amazon review checker” is steadier.
