# CarrierSource Free Data Collector

> Open-source Chrome Manifest V3 extension from INDUS Web Agency that reads freely visible CarrierSource carrier cards in the browser and exports CSV or Excel. It is not an official CarrierSource product.

CarrierSource Free Data Collector collects only data already visible on CarrierSource result pages and free profiles. It uses DOM APIs, stores records in IndexedDB on the user’s machine, and does not call the CarrierSource API, collect contact details, or bypass access controls.
