## srv.us

- `egress/srv-us` | fails-egress | evidence documented | binding none | category tunnel (SSH, HTTP/TLS only) | tier free
- needs card no, phone no, ID no, institution no | verified 2026-10-23 (live) | stale on 2026-11-23
- url https://docs.srv.us/
- price USD 0
- free tier: Free and fully open source. Stable URLs derived from your SSH key. No accounts. | unit: unlimited | metered on: none | read on: 2026-10-23 | source: [1]
- per-object cap: not applicable | source: [1]
- retention: not applicable | source: [1]
- egress: no quota published; the offer is 'Free and fully open source' with no account and no stated cap; ingress: http-only | metered: no | free allowance: none published | source: [1]
- identity: anonymous | detail: an SSH key pair and nothing else: 'Stable URLs derived from your SSH key. No accounts.' | country: None
- interface: ssh
- binding note: Nothing in the vocabulary binds because the transport cannot carry a UDP datagram at all; the limit is protocol, not quantity.
- interface detail: ssh srv.us -R 1:localhost:3000
- tooling: OpenSSH
- composes with: HTTP ingress only; composes with a web service and nothing that needs UDP
- reliability: one operator (xmit dev team); the tunnel lives only while the ssh session lives
- notes: Worth reading because it is the rare no-account service with a stable address, which is the property WireGuard needs. The protocol excludes it.
- evidence note: Raise by attempting a UDP forward with ssh -R and recording the server's refusal; not attempted because the service is documented as an HTTP terminator.
- extras:
  - wg_path: none
  - wg_detail: the service terminates TLS and speaks HTTP: 'expose any HTTP server to the Internet through a tunnel' and returns https URLs, so there is no UDP path
  - ingress: http-only
  - volume_stated: no quota published; the offer is 'Free and fully open source' with no account and no stated cap
  - bytes_transit: yes
  - transit_note: srv.us relays the HTTP traffic
- evidence:
  - [1] 2026-10-23: 'Yet another solution to expose any HTTP server to the Internet through a tunnel', 'Free & fully open source. Stable URLs derived from your SSH key. No accounts.'
