Show HN: Add 'unlock' to booking URL to auto-compare the same hotel across sites

I built this after getting tired of checking Booking, Expedia, Hotels.com, etc. one by one. Now if you have a hotel URL from Booking.com or Expedia, just add unlock before the domain — like: unlockbooking.com/… unlockexpedia.com/… It redirects to a lightweight site that compares that same hotel’s prices across major booking platforms. No login, no installs, just a shortcut to a comparison view. Example: Try this Booking.com link: https://www.booking.com/hotel/us/indigo-dallas-downtown.html?label=gen173nr-1DCAEoggI46AdIM1gEaIkCiAEBmAExuAEHyAEM2AED6AEB-AECiAIBqAIDuALDlo7ABsACAdICJGY0MzMyMjBhLTRjNGYtNDlkMy05YzdlLTIwOTkzMjg5OTZhNtgCBOACAQ&sid=4420c3f75f28604f84373b6fe57bcbc1&aid=304142&ucfs=1&arphpl=1&checkin=2025-09-16&checkout=2025-09-18&dest_id=20127504&dest_type=city&group_adults=2&req_adults=2&no_rooms=1&group_children=0&req_children=0&hpos=19&hapos=19&sr_order=popularity&srpvid=86ed879555bb05b0&srepoch=1745263027&all_sr_blocks=18333407_277287223_2_34_0&highlighted_blocks=18333407_277287223_2_34_0&matching_block_id=18333407_277287223_2_34_0&sr_pri_blocks=18333407_277287223_2_34_0__40500&from=searchresults https://www.booking.com/hotel/us/indigo-dallas-downtown.html... → Now add unlock: https://www.unlockbooking.com/hotel/us/indigo-dallas-downtown.html?label=gen173nr-1DCAEoggI46AdIM1gEaIkCiAEBmAExuAEHyAEM2AED6AEB-AECiAIBqAIDuALDlo7ABsACAdICJGY0MzMyMjBhLTRjNGYtNDlkMy05YzdlLTIwOTkzMjg5OTZhNtgCBOACAQ&sid=4420c3f75f28604f84373b6fe57bcbc1&aid=304142&ucfs=1&arphpl=1&checkin=2025-09-16&checkout=2025-09-18&dest_id=20127504&dest_type=city&group_adults=2&req_adults=2&no_rooms=1&group_children=0&req_children=0&hpos=19&hapos=19&sr_order=popularity&srpvid=86ed879555bb05b0&srepoch=1745263027&all_sr_blocks=18333407_277287223_2_34_0&highlighted_blocks=18333407_277287223_2_34_0&matching_block_id=18333407_277287223_2_34_0&sr_pri_blocks=18333407_277287223_2_34_0__40500&from=searchresults https://www.unlockbooking.com/hotel/us/indigo-dallas-downtow...

Would love feedback or suggestions! Planning to add filters, mobile UX, and maybe email alerts if there’s interest.
