Vehicle Routing Problem Solver API

POST your vehicles and jobs. Get back optimized routes.

You have a logistics problem, not an infrastructure problem. Hosted VROOM — no server required.

Why VRP Is Painful to Self-Solve

You have vehicles, jobs, time windows, and capacity constraints. You need optimized routes. Your options: implement a VRP solver yourself (academic rabbit hole), pay enterprise pricing for a route optimization platform, or wrangle open-source tooling onto your own server. There's a simpler option.

VRP is NP-hard

You're not writing this from scratch. Even approximate solvers are research-grade software. This is not a weekend project.

Enterprise platforms lock you in

OptimoRoute, RouteCloud, Google's Route Optimization API — they work, but you're looking at hundreds per month and proprietary request formats.

You just want an API

POST jobs and vehicles, get back optimized assignments. One call. That's it.

Hosted VROOM — Just Send JSON, Get Routes

Simple Routing hosts VROOM, the open-source vehicle routing solver, backed by OSRM for real road network distances. You send JSON, we solve the VRP, you get routes.

Multi-Vehicle Routing

Assign jobs across any number of vehicles. VROOM finds the optimal split automatically.

Time Windows & Constraints

Specify delivery windows, vehicle capacity, job durations, and pickup/delivery pairs. VROOM handles the constraints.

Real Road Distances

Backed by OSRM — travel times are based on actual road network routing, not straight-line estimates.

Standard VROOM API

The request/response format is standard VROOM JSON. No proprietary schema to learn, no lock-in.

Live Demo: 2 Vehicles, 10 Deliveries

Two vehicles starting from different depots. Ten delivery jobs scattered across the city. One API call to assign and sequence everything optimally.
