Every other interface quotes you one route and asks you to trust it. This one quotes every route we can reach at the same time, ranks them, and shows you exactly what each of the others would have cost. You do not need an account to use it.
We show what you did not take and what it would have cost. A comparison that hides the runners-up is not a comparison.
The confidential route is quoted next to the public one, so you can see the exact difference before you commit rather than take privacy on faith.
Costs are already inside the numbers being compared. A fee-free quote next to a fee-bearing one would flatter us and mislead you.
