Comparable listings are pre-computed from the meaning of each store listing, then shown with the audience and rating from our latest pass over the store. Access compares where each listing can run (every site, how many site patterns) and how many browser permissions it declares, against the extension it would replace. Narrower is not a verdict on safety: compare what each needs for the job.
