When he mentions Open route serice, I assume none of the route calculations is done by himself, so Optimile is just an UI for Open route service.

I see, thanks!

Open Route Service [1] uses Vroom [2] under the hood. It seems to be based on local search with some "Solomon I1" (?) heuristic. So good heuristic routes (obtained quickly), not optimal ones.

Exactly, the free version here uses Vroom under the hood with ORS. However I do have a branch with other VEhicle routing engines, but it wouldn’t bring too much value unless you had a very specific use case that I could apply it too.
