Mängelmelder

Mängelmelder is a free Chrome extension and mobile app designed to empower residents across Germany to report public infrastructure issues such as potholes, graffiti, and improperly disposed garbage. With a few simple steps—taking a photo, adding a description, and sending—it automatically captures the location via GPS and forwards the concern to the responsible city council.

The extension supports multiple German cities including Essen, Bremen, Mannheim, and more. Users receive email notifications confirming their report has been forwarded and ongoing updates about the resolution status. For those without smartphones, reports can also be submitted directly through the official website. This seamless, user-friendly tool fosters community involvement in improving city environments by simplifying communication with local authorities.
