Hi everyone I built Distance by Postcode after a logistics manager at work needed to calculate driving distances between a few hundred UK postcodes. Most tools we tried were either manual one by one, only offered “as-the-crow-flies” distances, or hid pricing behind opaque plans. So I built a tool using the Google Distance Matrix API that calculated driving distance and estimated travel time between postcode pairs at scale, specifically using the roads, just like inputting a pair of postcodes into Google Maps and it picking the shortest distance by default. After it proved useful internally, I decided to turn it into a simple public website and keep everything as straightforward and transparent as possible. The tool supports both single look-ups and bulk calculations, either entered manually or uploaded via CSV, XLS, or XLSX files. Once processing is complete, users can download a CSV containing the distances and estimated travel times for each postcode pair. Users can also create a profile to save their API key for future use and keep a history of previous calculations, which can be re-downloaded at any time. You can bring your own Google API key and use the tool for free (only paying Google directly for however many tokens you use), or use our API key with simple pay-per-calculation price of £0.01 per calculation. There is a minimum charge of £0.30 but that is set by Stripe, that is their minimum charge, if I could set it lower I would. It only currently works for UK postcodes but I plan on expanding that in the future. Thanks for checking it out. I’d love any feedback or ideas for improvement!
