Real road routes, not rulers
A driving route runs 20 to 40% longer than the straight line a spreadsheet estimates. That gap is the whole argument.
Everywhere you work
Windows Excel, Sheets, LibreOffice, your own code, an AI agent, or a file you upload. Same answers, same data.
Accurate and dependable
Authoritative data sources and battle-tested calculations you can trust.
Three products that qualify each other
They differ on who carries the provider relationship, so the right one depends on your volume, not on a feature chart.
Not sure which one you need?
It comes down to volume and who manages the API keys. Run one file occasionally and CDXStreamer is the shortest path. Run tens of thousands of routes a month in Excel and CDXZipStream's own-key model costs a fraction per call.
