Defikataster

Defikataster is a reliable Chrome extension providing access to Germany's largest and most comprehensive database of Automated External Defibrillators (AEDs). Operated by the nonprofit organization Definetz e.V., the database includes over 27,000 AED locations, ensuring users can find the nearest life-saving defibrillator swiftly in emergencies.

Unlike other user-controlled apps, Defikataster relies on a network of trained volunteers and full-time staff to verify and update detailed information about each AED, including operator data, maintenance status, and accessibility. A unique feature of this extension is the real-time display of mobile defibrillator units, allowing even faster assistance. Supported entirely by donations, Defikataster represents a vital tool in improving emergency response times across Germany.
