Ngrok

Creates a secure, encrypted tunnel that exposes local macOS Cactus services to cloud-deployed applications via public HTTPS endpoints.

ngrok establishes immediate ingress for the Cactus service running on a local Mac, bypassing NAT and firewall restrictions with a single command like 'ngrok http 8080'. It generates a stable, public HTTPS URL (e.g., https://cactus-dev.ngrok-free.app) that allows cloud-deployed apps to reach local webhooks and APIs instantly. This setup removes the friction of complex VPNs or static IP configurations during the integration phase: just run the binary, copy the URL, and start testing.
