People who stopped overpaying.
Booked the same room for €312 less. The overlay just popped up while I was checking out — felt like cheating.

FAQ
Questions, answered.
Is Hotel Deal Scanner really free?
Yes — 100% free, no sign-up. We earn a small referral fee when you book through a cheaper price we surfaced. You always pay less, never more.
Is it safe? What data do you collect?
Nothing personal. The extension only looks at the hotel page you're already on to compare prices. No accounts, no analytics, no tracking, no cookies.
Will it slow down my browser?
No. It's 91 KB, built on Manifest V3, and only activates on supported booking sites. You won't notice it's there until it saves you money.
Which booking sites does it work on?
Booking.com, Expedia, Hotels.com, Agoda, Trivago, Kayak, Hotwire and Priceline — eight major sites covering most of the hotel market.
How do you find a cheaper price?
We compare the exact same room and dates against b0arding.com, our partner inventory. When their price is lower, we show it. When it isn't, we stay out of your way.
Can I uninstall it anytime?
Of course — one click from chrome://extensions. No account to delete, no data to clean up.
