What is cftunnel?
cftunnel is a cross-platform command-line utility that makes local services reachable from the internet. It bundles two separate tunneling engines: Cloud mode relies on Cloudflare Tunnel to give you free HTTPS and WebSocket tunnels with automatic TLS and a global CDN, needing only a free Cloudflare account. Relay mode uses frp to provide self-hosted TCP and UDP tunnels, which work well for gaming servers, databases, SSH access, and remote desktop. Both engines can operate together. The program handles configuration, fetches engine binaries on its own, registers as a system service (systemd, launchd, or Windows Service), and includes one-command quick tunnels, custom domain support, password protection, QR-code sharing, scenario presets, a portable mode, and a desktop GUI companion. It is written in Go and released under the MIT license.
Should you self-host cftunnel?
cftunnel scores 51/100 on selfhost.directory (how scoring works) and ranks #2 of 10 in Network. It has 360 GitHub stars.
It shipped 10 stable releases in the past year. The latest, v0.4.4, came out on 26 September 2026. New versions land roughly every 1 days.
