Free tier	no service and no account; source and pre-built static binaries unit none; metered on none
Price	USD 0
Per-object cap	not applicable
Retention	not applicable
Egress	not applicable; the software states no volume; ingress: tcp free_allowance: none published
Identity	anonymous no account; both ends are hosts the operator controls
Binding	none the constraint is a root Linux host with raw socket access at both ends, outside the seven-kind vocabulary
Interface	cli udp2raw_amd64 -s / -c
Tooling	static binaries for x86, ARM, Android and some OpenWrt routers
Composes with	only composes with a host the client rents or gets free, such as a free-tier VM, and adds nothing to a hosted tunnel.
Reliability	needs root and iptables rules (-a), which is a common silent failure; the README states it survives reconnects and keeps UDP conversations valid
Notes	WireGuard's own limitations page names this project, which is why it stays despite a 2023 release. It forges IP and TCP headers, so it cannot ride a CDN or any managed forwarder: the far end must be a host that accepts the forged connection. That is the opposite of the wstunnel case.
Evidence rung	documented a measured run through a named path would raise it; no throughput number is published
Checked	2026-10-23 (live); stale on 2026-11-22
Parsed numbers	`$.price_per_tb_month` price-per-tb USD0.0 TB / month
