Free tier	Free tunnel (registered users): permanently free, 1M bandwidth, 2 GB traffic per month, HTTP/TCP/UDP tunnels, random domain or random TCP/UDP port, forced domain/port change at intervals. [translated] unit GB; metered on downloaded-bytes
Price	USD 0
Per-object cap	not applicable
Retention	not applicable
Egress	2 GB per month on the free tunnel.; ingress: udp free_allowance: 2 GB per month on the free tunnel.
Identity	email Registration with a Chinese phone number is the normal path; the free tier is labelled 'registered users'.
Limits	volume-quota 2 GB per month source per-ip-shaping 1 Mbps source request-rate random port is reassigned at intervals source
Binding	volume-quota 2 GB per month fails 1 TiB by a factor of about 550, and the 1 Mbps cap would fail it too: 1 Mbps sustained is roughly 0.32 TB per month.
Interface	cli Vendor client for Windows/Linux/macOS plus a web console.
Tooling	vendor client plus frpc-compatible config
Composes with	Not viable as a WG endpoint because the port is not stable.
Reliability	Random public port is reassigned at intervals, so any fixed endpoint stops resolving.
Notes	The port-insecurity sentence is the interesting part for UDP: a WG endpoint written into a conf file goes stale without notice. The nodeloc roundup separately warns each free tunnel lasts only 3 days, which contradicts the vendor's 'permanently free' label; the vendor says the tunnel persists but the address changes.
Evidence rung	documented All three numbers are on the vendor's own pricing block. A probe would only confirm the port rotation interval.
Checked	2026-10-23 (live); stale on 2026-11-22
