etr is a Rust reimplementation of Eternal Terminal (et) — a remote shell that automatically reconnects without interrupting your session.
This project is entirely vibe coded — every line was written by AI (Claude and Gemini) with a human directing at a high level. The code compiles, the tests pass, and the tool works, but it has not been reviewed by an experienced systems or networking engineer.
Real programmers are welcome. If you spot something wrong, fragile, or just un-idiomatic, please open an issue or a PR — your expertise is exactly what this project needs.
Eternal Terminal was created by Jason (Jez) Gao and the et contributors as an answer to a simple frustration: SSH sessions die when your network hiccups, your laptop sleeps, or you switch Wi-Fi. ET keeps the remote shell alive and reconnects transparently, so your work never gets interrupted.
etr is a from-scratch Rust reimplementation of that idea, with a mosh-like bootstrap model (no pre-running daemon needed), QUIC transport, and TLS 1.3 security.
