Stayonomy answers travel questions with real, bookable prices instead of estimates. It compares every way to get between two cities - flight, train, bus and ferry - with durations and current cached fares in EUR; finds the cheapest days and months to fly; lists hotels with nightly rates; and covers the rest of the trip too: car rental at the destination, prepaid travel eSIM plans with catalog prices for 200+ destinations, tours and tickets, city guides, and month-by-month climate advice.
Fares are real prices travellers found recently, refreshed daily and served from Stayonomy's own database - every answer says how fresh the data is, and the booking site confirms the final price. All tools are read-only; the app needs no account and collects no personal data. Booking links may contain affiliate identifiers, which is how Stayonomy is funded; this never affects the prices shown.
Operated by Starcode Services Kft. (Budapest, Hungary).
