Why Hopper's alerts are deliberately simple
Hopper has predicted fares for a decade, and its alerts stay basic. That is not a technical shortcoming: it is a business model choice.
How we compare
Kestrelia is one of the tools compared, and we are the ones writing. We hold no affiliate relationship with Going, Hopper or Google: we gain nothing if you choose them, and nothing if you book a flight either.
Prices and tiers come from each service's public pages, with the date they were checked stated in every write-up. The capabilities described are the ones each service documents publicly.
Prices change and first-year promotions are common. Check the service’s own page before paying, and tell us about any error: we would rather fix it than leave it standing.
