Ask any delivery operation where its money actually goes and the honest answer is almost always the same: the last mile. Trucks leave the depot full and efficient, and then it all unravels at the end — one driver zig-zagging across a neighborhood, doubling back for a stop they rolled past twenty minutes earlier, idling outside an address that doesn’t open until noon. Last mile route optimization is the work of squeezing that final leg down to the least driving, the fewest miles, and the most stops actually served. I spent two decades building optimization models for exactly this kind of problem, and I eventually turned one of them into a free tool. Here’s why the last mile is so stubborn, and how a solver beats a map every single time.

My Free Vehicle Routing Optimizer Just Got Smarter
I’ve been turning twenty years of Operations Research models out of dusty Excel files and onto the open web, one at a time. The vehicle routing one — the free vehicle routing optimizer that lives at routing.kindoflost.com — just got a round of upgrades that make it a lot less fussy to actually use. None of it changes the price (still free, still runs in your browser), but it removes most of the friction that used to make people bounce off it.
Pickup and Delivery Route Optimization (Free Tool)
If you’ve ever tried to plan a pickup and delivery route by hand — grab a package here, drop it there, then double back across town for the next pickup — you’ve felt how fast it stops being a map problem and turns into a logic puzzle. Every delivery depends on a pickup happening first, every vehicle has a limit, and every stop has a window when it can actually happen. I spent two decades building optimization models for exactly this kind of problem, and I eventually turned one of them into a free tool anyone can use. Here’s what makes pickup and delivery routing genuinely hard, and how to stop solving it by guesswork.

RouteXL Alternatives: Free Multi-Stop Route Planners
I spent twenty-plus years building vehicle routing models for companies that paid serious money for them, so when I went looking at RouteXL alternatives recently, I wasn’t shopping — I was checking out the neighborhood. RouteXL is probably the best-known free multi-stop route planner on the internet, and for good reason: paste in your addresses, get them back in a sensible order, free up to 20 stops. But 20 stops is exactly where a lot of real delivery days start, and that’s where the free tier ends. This post is an honest tour of what’s out there — including the free VRP tool I built and run myself — and which one fits which kind of routing problem.
Twenty Years of Models, One at a Time
I’ve been doing operations research for over 20 years. Most of what I’ve built is locked inside Excel files on a hard drive. Not because Excel is where OR models belong — it isn’t, really — but because that’s where the data was, that’s where the clients were, and that’s what worked at the time.
The backlog is real. Staff scheduling, vehicle routing, warehouse slotting, least-cost formulation, a few others. Each one took months to build and calibrate. Each one is doing nothing right now except existing as a .xlsm file.
