Aero uses ngrok to provide a comprehensive auto-moderation toolkit for Discord by scanning thousands of communities for fraudulent URLs, malicious actors, and impersonators. Moderators configure these filters using a chatbot, and Aero uses ngrok's Node.js SDK to programmatically define endpoints and ports, allowing easy deployment and remote access. Ngrok is used to provide a static URL that remains reachable regardless of the deployment method, such as bare-metal hardware or Kubernetes pods, enabling monitoring tools like Prometheus to track growth and detect trends in malicious behavior. The use of ngrok also allows for authenticating requests and serving static files, enhancing the application's functionality.
