Cloudflare Tunnel

Secure Tunnel/Zero Trust Network Access C DevOps & Hardware

Basic Information

Product Description

Cloudflare Tunnel (formerly known as Argo Tunnel) is part of Cloudflare's Zero Trust suite, establishing a secure private connection between user infrastructure and Cloudflare's global network. Through the lightweight daemon cloudflared, it creates outbound-only connections, allowing internal services to be securely published to the internet without requiring a public IP or opening firewall ports. The basic features are completely free, making it the best solution for securely exposing self-hosted OpenClaw to the public internet.

Relationship with OpenClaw Ecosystem

Cloudflare Tunnel is an ideal solution for securely publishing self-hosted OpenClaw services from home to the internet. Users do not need a public IP or to configure router port forwarding; simply running cloudflared allows secure access to OpenClaw via a custom domain. Cloudflare's DDoS protection ensures OpenClaw services are not attacked. Zero Trust policies can restrict access to OpenClaw to authorized users only, significantly enhancing security.
