I built OpenSesh, an open-source MobaXterm/Termius alternative in Rust and Qt 6

Описание и применение

OpenSesh – это открытый клиент для удалённых соединений, объединяющий терминалы, SSH, SFTP, туннели, RDP и другие протоколы в одной нативной программе для Windows и Linux.

Задача

Users working with servers need multiple tools (terminal, SSH client, SFTP, tunnels, RDP) that are often closed‑source, Windows‑only, subscription‑based or Electron‑based.

Результат

OpenSesh delivers a unified, open‑source remote‑connection experience with native performance, extensive protocol support, and robust security, replacing multiple closed‑source tools.

Рабочий процесс

• Install OpenSesh via curl script or installer
• Import hosts from ~/.ssh/config, MobaXterm, PuTTY, Remmina or CSV
• Use GPU‑rendered terminals with tabs and panes
• Connect via SSH with jump hosts, proxies, agents, certificates
• Transfer files with SFTP or S3 in a two‑pane view
• Set up local/remote/SOCKS tunnels
• Access RDP/VNC desktops in tabs
• Monitor server resources via agentless shell loop
• Record sessions and use snippets/macros
• Sync settings across devices with Git or Syncthing

Доказательства

If you work with servers, you probably have a pile of tools open at once: a terminal, an SSH client, something for SFTP, something for tunnels, maybe an RDP client too.

So I built OpenSesh: a free, open-source and native remote connections client for Windows and Linux.

Terminals: a GPU-rendered terminal for every shell you have (PowerShell, cmd, Git Bash, WSL, /etc/shells), with tabs that split into panes, move between windows and broadcast input.

Источник

SSH: a built-in client with jump hosts, proxies, agents, one-time codes, certificates and auto-reconnect.

Источник

Files: SFTP and S3 (AWS, MinIO, RustFS) in a two-pane view, and a side panel that follows your terminal's current folder.

Источник

How it's built: Rust for the core, with the UI in Qt 6 / QML through cxx-qt. No Electron and no webviews.

Secrets live in a vault encrypted with XChaCha20-Poly1305. Its key is held by the system keyring or an Argon2id master password.

Releases: each package is installed and launched on a clean Debian, Ubuntu, Fedora, Arch and Windows system in CI before it's published.
