Install
One command on macOS and Linux:
curl -fsSL https://raw.githubusercontent.com/timhartmann7/omnyssh/main/install.sh | sh
The script detects your OS and architecture and installs the latest desktop build — into /Applications on macOS, your app menu on Linux. Want the terminal app instead, or both? curl … | sh -s -- --tui (or --both). Prefer clicking? Grab the file for your platform from Releases.

No account, no login screen, no telemetry. The app opens with an empty dashboard and reads your existing ~/.ssh/config if you have one — hosts behind a bastion (ProxyJump) included.
What it does
You add a server once. After that it sits on the dashboard as a card with live CPU, RAM and disk, uptime, distro, the top processes eating your CPU, and a badge for what runs on it. One click on sh drops you into a real PTY terminal. One click on files opens a two panel SFTP browser. Ten servers fit on one screen and refresh on their own.
Live dashboard
Cards for every host with CPU, RAM and disk bars, uptime, OS version, top processes, and a Docker badge showing how many containers are up. Bars turn yellow, then red, so a sick server is obvious from across the room.
Real terminals
Full PTY sessions in tabs. Open as many servers as you need, switch between them from the sidebar, and keep them running while you work in the dashboard.
Two panel SFTP
Local on the left, remote on the right. Tick the files you want and move them across, watch the progress bar, select many at once. Nobody remembers scp -r syntax anyway.
Snippets
Save the commands you paste every week. Pick a snippet, tick the hosts to send it to, and it runs on all of them at once. Snippets take parameters, so sudo systemctl restart {{service}} asks you for the name.
Search everything
Hit ⌘K and start typing. Every host you have, plus every session already open. Enter drops you into a terminal on the host you picked, or back into the session you left.
Streamer mode
Swaps every real IP on screen for a fake one. Record a demo or share your screen without leaking client infrastructure.
Light and dark themes
Both ship in the app. Switch from the sidebar.
Small
Around 130 MB of RAM with several sessions open, on a 20 MB download. Termius on the same machine, doing nothing, sat at 649 MB across nine processes. Full numbers in the comparison.
SSH key setup
Password auth on a fresh VPS is the thing you always mean to fix and never do. OmnySSH does it in one click.
Pick a host you added yourself that has no key configured, hit Set up SSH key, and the app generates an Ed25519 key, appends the public half to authorized_keys, and switches the host over to key auth. It then opens a fresh connection with the new key to prove the key works, and only after that does it turn password login off. There is no confirmation step in between: starting the flow means going through with it.
Before touching sshd_config it saves a backup on the server. If any step fails, it restores the backup and leaves your access exactly as it was. Your private key never leaves your machine, and nothing gets sent anywhere except the server you chose.
The code lives in crates/omnyssh-core/src/ssh/key_setup.rs. Read it before you point this at production. That is the whole point of shipping it open source.
Keys with a passphrase work too. When a key is encrypted, OmnySSH asks for its passphrase once and keeps it in memory until you quit; it is never written to disk. On macOS and Linux a key already loaded in ssh-agent is used without asking. The host Password field is the server login password, not a key passphrase.

tmux stays in the table because it is what most of us actually use. It wins on weight and loses on everything visual.
The TUI version
OmnySSH started in the terminal, and the TUI is still here, still maintained, still gets releases.
Same engine underneath: the repo is a cargo workspace where crates/omnyssh-core holds the logic and the frontends sit on top. Dashboard, SFTP, snippets, multi session tabs, fuzzy search, plus four themes (default, dracula, nord, gruvbox) and remappable keys in config.toml.
# cargo
cargo install omnyssh
# homebrew
brew install timhartmann7/tap/omnyssh
# nix
nix run github:timhartmann7/omnyssh
Then run omny. Press a to add a host, / to search, ? for help, Shift+K to set up keys on the selected host.
Prebuilt TUI binaries for Linux, macOS, Windows and Termux live on the Releases page under the omny-* files. Config sits in ~/.config/omnyssh/ on Linux, ~/Library/Application Support/omnyssh/ on macOS, %APPDATA%\omnyssh\ on Windows. Your ~/.ssh/config is read at startup and never written to.
Full options, keybindings and config examples: man omny.
Dev notes
I write about what I am building on Telegram. Release notes, work in progress screenshots, benchmarks, and the things that broke on the way there. Usually before they show up anywhere else.
Contributing
Pull requests welcome. CONTRIBUTING.md has the setup, the conventions and the checklist. Open an issue first if you plan something big, so we do not both build it.
