Where you decide, not where you book.

Klugfy answers the question booking sites can't: should I actually go? Built on open data and honest math — no upsell theatrics, no opaque rankings.

Seven open sources. One honest pipeline. Re-baked daily.

Klugfy never invents numbers. When a value is estimated (e.g. "based on great-circle distance"), we say so on the score. Earns trust faster than hand-waving.
