Check the current page for Google Maps JavaScript API signals, visible errors, loaded libraries, and map containers. Google Maps API Checker helps developers, local SEO teams, and small-business website operators inspect Google Maps setup clues without opening DevTools. Run a scan on the active page to see whether the Google Maps JavaScript API is observable, which optional libraries are requested or loaded, how many map containers are visible, and whether common visible error clues appear on the page. The report separates observed findings from inferred findings, so URL-format clues are not treated as confirmed API validation results. Free features: - Current-page Maps JavaScript API diagnostic. - Observable loaded/requested library list. - Rendered map container and iframe embed counts. - Visible Maps error clue detection. - Plain-text report copy. Supporter roadmap: - Save reports by domain. - Export client-ready Markdown/PDF reports. - Multi-page URL scans.
