A Boring Announcement: Free Tunnels for Everyone

This post introduces Cloudflare Tunnel (formerly Argo Tunnel) as a free service for establishing secure, outbound-only connections from origin servers to Cloudflare. This significantly enhances Zero Trust security by eliminating the need to expose origin IPs or manage complex firewall rules, allowing all traffic to be inspected and controlled by Cloudflare. The post also details improvements to Tunnel's stability and persistence, including the removal of internal dependencies, migration to Cloudflare's edge load balancer Unimog, and the introduction of Named Tunnels for autonomous reconnection, further strengthening the security and reliability of origin connectivity.
