unmatched when your problem doesn't fit standard VRP boxes — arbitrary custom constraints, fairness rules, skill matching — expressed in code rather than fixed API parameters, with a real company behind support and continuous solving for same-day insertion","fix":"It's a solver, not a routing stack — you bring your own distance matrix and map data, and modeling custom constraints demands real engineering investment versus a fill-in-the-JSON API"},{"rank":5,"product":"HERE Tour Planning API","reason":"The credible enterprise alternative to Google — solid VRP coverage (multi-depot, mixed fleets, break rules) tightly coupled to HERE's truck-attribute map data, which makes it the strongest pick specifically for fleets running actual trucks (height/weight/hazmat restrictions) rather than vans;
