Free tier	Apache-2.0 client and server; no hosted free tier found unit none; metered on none
Price	none stated
Binding	volume-quota the software imposes no limit, so what runs out first is the monthly egress allowance of the host it runs on, and that host is a separate provider with its own bill
Identity	anonymous the software needs no account
Egress	not published
Interface	cli frpc against your own frps
Tooling	frp
Composes with	composes only with a server that a user pays for, so it is self-hosted software, not a free service.
Reliability	no credible free public frps was found; every 'free frp server' lead was a VPS advertisement
Notes	A tool rather than a service, recorded so a reader searching for free tunnels meets that fact. The row was `qualifies`, which read as a free service. The software is free and the path is not, because it needs a host a user does not own. It is usable only on a rented or free compute service, and that service is the finding, not frp.
Evidence note	measured frps and frpc 0.71.1 ran on this host: a 4,194,304-byte object read back through the TCP proxy byte-identically, sha256 46386cf4dbccceb80f80148d46d37f1a30d72912089cfbe4b3e51d9d55a79747, 42.91 MiB/s against a 38.73 MiB/s direct baseline. No hosted free tier exists, so this measures the software and not a service
