cloudflaredm is a stripped-down derivative of Cloudflare's cloudflared, built for small edge routers on mobile networks.

This fork exists for deployments where the tunnel client needs to:

• only use token-authenticated named tunnels
• fit on constrained router-class hardware
• stay as small as possible (< 9Mb on ARMv7)
• use less idle traffic than stock cloudflared

This fork is intentionally narrow.

It only supports:

• basic tunnels
• local HTTP origins (no local TLS)
• local WebSocket origins

It does not aim to support the broader cloudflared feature set.

Within that supported scope, this fork also reduces non-essential runtime overhead around telemetry, metrics, and diagnostics.

This fork also changes a few runtime defaults:

• --ha-connections defaults to 3 instead of 4
• QUIC advertised max idle timeout defaults to 10s
• QUIC keepalive period defaults to 5s

Both QUIC values are exposed as arguments:

• --quic-max-idle-timeout
• --quic-keepalive-period

Note on real-world behavior:

• as observed on June 6, 2026, Cloudflare still negotiates these down in practice to 5s max idle timeout and 2.5s keepalive
• despite this, default parameters still yield a 70% reduction in idle traffic

This repository is a maintained downstream derivative, not a general-purpose replacement for upstream cloudflared.

If you need the full product surface, use upstream instead.
