## localhost.run

- `egress/localhost-run` | fails-egress | evidence documented | binding per-ip-shaping | category tunnel (hosted, SSH)
- needs card no, phone no, ID no, institution no | verified 2026-10-23 (live) | stale on 2026-11-23
- url https://localhost.run/docs/
- free tier: free random subdomain over SSH, no account | unit: unlimited | metered on: wall-clock | read on: 2026-10-22 | source: [1]
- per-object cap: not applicable: a stream
- retention: the subdomain rotates per session | source: [1]
- egress: speed-limited with no published value; measured 11.4 KiB/s, about 0.98 GiB/day | metered: no | source: [1]
- identity: anonymous | detail: the nokey@ ssh target needs no account
- interface: ssh
- limits:
  - per-ip-shaping (binding): 4,128,768 of 104,857,600 bytes in 180 s on a 100 MiB object, and 1,027,916 of 1,048,576 in 90 s on a 1 MiB object probe
- binding note: two objects of different sizes hit the same ~23 KB/s aggregate ceiling, so it is shaping.
- interface detail: ssh -R 80:127.0.0.1:PORT nokey@localhost.run
- tooling: OpenSSH
- composes with: composes with nothing: at 11.4 KiB/s a request/response API is usable and no bulk transfer is.
- reliability: the free hostname is a random <hex>.lhr.life subdomain that changes every session
- notes: The measurement makes it fails-egress: 11.4 KiB/s is 0.98 GiB/day, 0.1% of one day's workload.
- extras:
  - stale_after_days: 180
  - bytes_transit: yes
  - transit_note: the tunnel carries the origin's bytes, at a measured 11.4 KiB/s
  - wg_path: none
- evidence:
  - probe:https://2ea044f1475bd0.lhr.life/blob100m.bin 2026-10-22: 200 with 4,128,768 of 104,857,600 bytes in 180 s, then the client timeout
  - probe:https://2ea044f1475bd0.lhr.life/blob1m.bin 2026-10-22: 200 with 1,027,916 of 1,048,576 bytes in 90 s, then the client timeout
  - probe:https://2ea044f1475bd0.lhr.life/small.txt 2026-10-22: 200, 3 bytes in 1.75 s: the control path works
