{"slug":"best-route-optimization-apis-for-last-mile-delivery","title":"Best route optimization APIs for last-mile delivery","question":"What are the best route optimization APIs for last-mile delivery in 2026?","verdict":"As of 2026-08-09, Claude and Gemini collectively rank Google Maps Platform Route Optimization API #1 for route optimization apis for last-mile delivery on ModelsAgree — unanimous among the 2 models that have answered. The models' case: Built on Google's OR-Tools solver and paired with the industry's best road, traffic, and ETA data, so its optimized routes hold up in the real world. The models' main caveat: Pricing is high and hard to forecast, and it pulls you into GCP. The strongest alternative is NextBillion.ai — Purpose-built for fleet and last-mile routing with a rich constraint model (time windows, capacities, driver breaks, zones) at meaningfully lower cost.
