etunnel for Python
websocket-client based.
Zero registration: every SDK client speaks the same tiny wire protocol
(PROTOCOL.md) against any etunnel server
(default wss://t.etun.uk/tunnel).
Install
pip install etunnel
Python >= 3.8 (websocket-client installed automatically).
CLI
etunnel 3000
Prints TUNNEL_URL: https://<subdomain>.t.etun.uk — that URL now routes to
your local service. Ctrl-C closes the tunnel.
Reconnects automatically. If the connection drops (including a server
restart) the CLI re-dials with exponential backoff (500ms → 30s, ±20%
jitter, reset on success) and prints TUNNEL_URL: again. The subdomain is
reclaimed, not re-randomised: the client replays the server's signed
resumeToken in hello.resume, so links already shared keep working (the
server needs a stable SESSION_SECRET; see PROTOCOL.md §1). Set
ETUNNEL_RECONNECT=0 to restore the old one-shot behaviour.
Embed
from etunnel import connect
t = connect("wss://t.etun.uk/tunnel", 3000, {})
print(t["url"])

License
MIT — see LICENSE. Buffer-based protocol client: request and response bodies are buffered per stream (fine for webhooks/dashboards/demos; use the Go SDK for streaming and WebSocket pass-through).
