Comparoute – See how Trimble, HERE, and TomTom calculate the same truck route differently

I'm building Comparoute because I noticed something frustrating when working with truck routing APIs: the same origin-destination pair gives you wildly different results depending on which provider you use.

The problem:

If you're building logistics software or managing a fleet, you're probably locked into one routing provider. But Trimble (PcMiler), HERE Maps, and TomTom can differ by 20-50 miles on a cross-country route – and those

differences compound into real money (fuel, tolls, driver hours).

What I built:

A simple tool that lets you enter origin/destination coordinates and instantly see how each provider calculates:

- Distance

- Duration

- Toll costs

All for the same truck profile (standard 48-foot semi-trailer, 80,000 lbs).

No signup required for a few test comparisons.

Why I'm posting:

I'm validating whether this is actually useful. My hypothesis: developers integrating routing APIs and fleet managers choosing providers would benefit from seeing these differences before committing to a vendor.

Questions:

1. If you work with routing APIs – do you ever compare providers? How do you currently do it?

2. Would an API that normalizes the response format across providers be valuable?

3. What other data points would matter for your comparison (fuel estimates, CO2, route geometry)?

The codebase is Next.js + TypeScript. I'm considering open-sourcing the provider abstraction layer if there's interest.

Looking forward to feedback – even if it's "this already exists" or "nobody needs this."
