Free tier	no service and no account; a patch to the Linux kernel WireGuard module with Ubuntu 24.04 binaries unit none; metered on none
Price	USD 0
Binding	none both peers must run the patched kernel module, which means two hosts with module build or install rights; that is outside the vocabulary
Identity	anonymous no account
Egress	not applicable; the software states no volume; ingress: tcp free allowance: none published
Interface	cli wg and wg-quick unchanged
Tooling	Ubuntu 24.04 amd64 and arm64 archives, or build from source
Composes with	composes only with hosts where the operator controls the kernel, so a free-tier VM works and a managed tunnel does not.
Reliability	out-of-tree kernel patch for a specific kernel and distro; both peers must match
Notes	The only project that removes the extra hop instead of adding one: TCP framing happens in the kernel module, so there is no proxy process and no userspace re-encapsulation. It still needs a peer at the other end running the same patched module, so it does not reach a hosted tunnel, and installing a patched kernel module on both ends is a heavier commitment than running a userspace wrapper. Its measured numbers are the author's, quoted here as reported.
Evidence note	documented a measured A/B against UDP WireGuard on a named path would raise it; the repository publishes its own comparison numbers, which are reported rather than reproduced here
