The secret to 10 minute delivery isn't driver speed

The secret to 10-minute delivery isn't driver speed. The average delivery distance is shorter than your morning walk. Dark stores are everywhere, hiding in plain sight.

I mapped quick-commerce infra in Indian cities. Every dark store, real routing data, actual coverage zones across major urban hubs, across Blinkit, Zepto, and Instamart.

The Problem We're Solving

Quick-commerce companies like Blinkit, Zepto, and Instamart promise 10-minute deliveries. But how much of a city can they actually reach in that time? This map answers that question by showing the true delivery footprint of every dark store.

Step 1: Finding All the Dark Stores

We needed the locations of every dark store across major Indian cities. A community member on Reddit (u/sigmaAs) had already mapped these stores using Google Maps. We exported that data as a geographic file (KML format) containing the exact coordinates of each store, organized by brand.

Result: A dataset of all known Blinkit, Zepto, and Instamart dark store locations across Bangalore, Mumbai, Delhi, Hyderabad, and Pune.

Step 2: Generating Coverage Zones (Isochrones)

Instead of drawing simple circles around each store (which would be inaccurate), we used isochrones. These are shapes that represent all the areas reachable from a point within a specific time, accounting for actual roads, one-ways, and traffic patterns.
