Mapbox Alternative: Kardinal's Route Optimization API
A factual comparison, based on Kardinal's open benchmark of 149 constraints. Kardinal is a route optimization specialist: 93% vs 14% coverage, 8 of 11 constraint families fully covered against 1, plus lexicographic optimization. Mapbox is a maps and geospatial platform whose Optimization API is a light routing add-on, not a fleet-constraint engine.

Kardinal's open benchmark, 149 constraints across 8 sectors. See the methodology
Mapbox is a maps, geocoding and navigation platform. Its Optimization API v2 solves basic routing and ties Kardinal on time windows, but on the benchmark it covers 14%: near zero on objectives, cost, capacity and real-time re-optimization. It is built for maps and navigation, not for modeling real fleet constraints.
For a route optimization API, Kardinal is the stronger choice: 93% vs 14% coverage, 8 of 11 families fully covered against 1, lexicographic optimization, and transparent self-serve pricing. Mapbox fits teams that primarily need maps, tiles and navigation SDKs.
Feature by feature
The same criteria, side by side. Coverage figures come from Kardinal's open benchmark of 149 real-world constraints.
| Criteria | Kardinal | Mapbox |
|---|---|---|
| Benchmark coverage (149 constraints) | 93% | 14% |
| Constraint families fully covered | 8 of 11 | 1 of 11 |
| Objectives & balancing | Full (100%) | Minimal (1%) |
| Route structure & limits | Full (100%) | Minimal (22%) |
| Pickup, delivery & returns | 95% | 35% |
| Capacity & load | Full (100%) | Minimal (11%) |
| Real-time re-optimization | Yes | No |
| Lexicographic optimization | Yes | No |
| Focus | Route optimization specialist | Maps & navigation platform (Optimization API v2) |
Maps, tiles and navigation
Mapbox shines as a maps and geospatial platform: map rendering, geocoding, navigation SDKs and a routing/matrix API. Its Optimization API v2 handles basic routing and ties Kardinal on time windows.
But on real fleet optimization it covers 14% of the benchmark: near zero on objectives, cost, capacity and real-time re-optimization. For modeling real operational constraints, that is where Kardinal takes over.
A real optimization engine, transparent pricing
Kardinal covers 93% of the 149-constraint benchmark against 14% for Mapbox, and fully covers 8 of the 11 constraint families against 1. It is built for operational constraints: objectives, route structure, capacity, cost and fleet economics, pickup and delivery, and lexicographic optimization.
And the access fits developers: transparent public packs, per stop with re-optimizations free within 24h, 1,000 free stops with no credit card, typed SDKs and an MCP server for agents. Kardinal handles the optimization and sits alongside whatever mapping stack you use.
If you also need field execution, our Laskar app takes over on the driver side, from the optimized plan to the completed route.
Pricing: transparent, self-serve packs
Mapbox publishes an Optimization API grid, but it bills per API request, not per stop, and its generally available version is a single-vehicle solver capped at 12 coordinates per request, so it cannot price a real multi-vehicle fleet. Kardinal's pricing is public and self-serve: prepaid stop packs, no subscription and no expiry, with re-optimizations free within 24h.
| Prepaid pack | Price | Price per stop |
|---|---|---|
| 2,000 stops | 99€ | 0.050€ |
| 10,000 stops | 299€ | 0.030€ |
| 50,000 stops | 999€ | 0.020€ |
| 250,000 stops | 2,999€ | 0.012€ |
Prepaid packs, no expiry and no commitment, plus 1,000 stops free to start with no credit card.
| API requests / month | Published price |
|---|---|
| Up to 100,000 | Free |
| 100,001 – 500,000 | $2.00 / 1,000 |
| 500,001 – 1,000,000 | $1.60 / 1,000 |
| 1,000,001 – 5,000,000 | $1.20 / 1,000 |

Mapbox bills per API request, not per stop. Its generally available Optimization API is a single-vehicle solver limited to 12 coordinates per request, so it cannot model a real multi-vehicle fleet; the multi-vehicle version is in public beta with no published price. A like-for-like per-stop comparison is therefore not possible.
Re-optimizations free within 24h
Optimize the same stops all day for no extra cost. You pay per unique stop within a plan, not per request.
Public and self-serve
Read the docs, test on 1,000 free stops and buy a pack on your own, no sales call to see a price.
In our developer survey, an unpredictable bill that could spike was the top pricing frustration, and nearly two-thirds were bothered by APIs without public pricing. See the survey.
Our verdict
The best test is your own data. Our free tier of 1,000 stops lets you check whether we cover your constraints before you commit.
You primarily need maps, geocoding and navigation SDKs, with only basic routing on top.
You need a real route optimization engine (93% vs 14%): objectives, route structure, capacity, cost modeling, lexicographic optimization and transparent self-serve pricing. For fleet-constraint optimization, Kardinal is the superior choice.
