Important limitations

The extension collects result cards visible when the collection action is triggered. It does not automatically scroll through results or collect additional pages. Extracted information depends on what Google Maps displays, and some fields may be missing. Changes to Google Maps page structure may require updates to the selectors or extraction logic.

This is an independent source-code project. It is not affiliated with, sponsored by, or approved by Google.

Before using or distributing the extension, buyers should review the applicable Google Maps terms, marketplace rules, and other relevant policies. The project does not include CAPTCHA bypass, proxy rotation, or stealth automation.

License and support

The package includes a draft proprietary source-code license. Buyers should review the final license terms and the marketplace’s applicable licensing conditions before use. Support and future updates are not unlimited unless explicitly stated in the listing.
