cloudflared: A command-line client that proxies traffic from Cloudflare Tunnel to origins without requiring firewall holes.

What problem it solves

Exposing an origin through Cloudflare Tunnel can require inbound network access, which conflicts with keeping the origin closed. The client connects the Cloudflare network to the origin and also supports access to protected origins for Layer 4 traffic such as SSH and RDP.

Key features

  • Cloudflare Tunnel connectivity — Runs a tunneling daemon between the Cloudflare network and an origin, forwarding requests without exposing the origin directly to inbound traffic.

    Source: README

  • Multiple routing options — Routes traffic through public DNS records, a public hostname managed by a Cloudflare Load Balancer, or private traffic from WARP client.

    Source: README, config

  • Layer 4 origin access — Provides command-line access to Tunnel origins for TCP applications, including use cases such as SSH and RDP.

    Source: README

  • Multiple installation formats — The client is distributed as standalone binaries, a Docker image, and Debian, RPM, and Homebrew packages, with platform-specific instructions.

    Source: README, Dockerfile

  • Reproducible local development — Provides Make-based targets for building, testing, formatting, linting, mock generation, and installing pre-push hooks.

    Source: README, Makefile

Who it may suit

This may suit operators who need to expose origins through Cloudflare Tunnel while keeping them closed to direct inbound traffic. It may also suit contributors who want to build and test the Go-based client from source.

Topics to discuss

  • Which Tunnel routing workflows should receive more complete command examples?

  • How can the documentation better explain origin access for Layer 4 workloads such as SSH and RDP?

  • Which development workflows need clearer setup guidance or additional automated checks?
