Every hotel list is an ad. HotelRoost ranks 245,901 hotels with a single published formula: guest ratings weighted by how much evidence is behind them, then re-based against the country they sit in. A 10/10 from twelve guests does not outrank a 9.1 from four thousand. No listing fees, no promoted placement, and the commission is identical whichever hotel you pick, so nothing can buy a position. 28,534 cities, 221 countries, four languages. The formula is published in full.

Could you build this?
Partial The public formula and ranking frontend are easy to build, but aggregating, normalizing, and continuously scraping or licensing clean review data across nearly 250,000 global hotels is an intensive data-engineering challenge.
What it would actually take: Building this requires large-scale data ingestion pipelines that scrape or license structured data from hundreds of OTAs (Booking, Google Places, TripAdvisor) while bypassing anti-scraping and deduplicating 250,000 global entity records across 221 countries. The backend would need distributed crawlers, proxy pools, entity resolution models (matching hotel names, geolocations, and facilities), and an automated Bayesian normalization pipeline. Data engineering at this volume requires continuous infrastructure maintenance and anti-bot mitigation expertise.
