One workspace.
Every connection.
Termalith keeps your servers, network gear and remote desktops in one window: SSH and Mosh terminals, SFTP, FTP and FTPS, RDP and VNC in a tab, tunnels, serial and Telnet consoles and network tools — free for any use, the same on every system, with your passwords in the system keychain and host keys checked every time.

Free, cross-platform, careful by default
Most all-in-one admin tools run on one system or keep everyday features behind a paid edition. Termalith is MIT-licensed, the same on all three systems, and holds the keys to your infrastructure with care.
Secrets stay in the keychain
Passwords and passphrases live only in the system credential store, saved only after a login worked, never in logs or on command lines.
No silent trust
Unknown host keys are shown; changed keys are refused. Tunnels listen on loopback, forwarding is opt-in, unexpected server channels are rejected.
Native on three systems
A small Rust core with a web UI (Tauri), the same features on macOS, Windows and Linux, Intel and ARM, tested in CI on all six builds.
Free for any use
MIT licensed, no paid edition, no account, no session limits. Use it at home or at work, read the code, change it.
Nothing phones home
No telemetry. Crash reports stay on your machine. The update check runs only when you ask, or at startup if you turn it on.
Master password & portable
Optionally seal saved passwords with a master password, or run from a USB stick with all data in a folder next to the app.
Get Termalith — free, for every system
The latest version for macOS, Windows and Linux. Pick your system, install, connect. Need help choosing? Which file do I need?
Every file is installed and started on its own system in an automated test before a release is published. Verify downloads with SHA256SUMS.txt (how). Older versions: all releases.
Then install it
- Open the
.dmgand drag Termalith to Applications. - Open it. macOS refuses the first time because the app is not signed with a paid Apple certificate yet.
- System Settings → Privacy & Security → Open Anyway (macOS 14 and older: right-click the app → Open).
- Allow local network access when asked, to reach machines on your network.
- Run the
-setup.exe(or the.msifor managed deployment). - If SmartScreen warns, click More info → Run anyway (the installer is not signed with a paid certificate yet).
- Start Termalith from the Start menu.
Needs WebKitGTK 4.1 and glibc 2.35+ (Ubuntu 22.04, Debian 12, Fedora 36 or newer). Saved passwords need GNOME Keyring or KWallet.
Needs Rust, Node.js 24 and the Tauri prerequisites for your system. Building and releasing
Then connect
- Click + to save a server, or Quick connect
- Confirm the server's host key once
- Open Files or Tunnels on the tab

Short answers
Is it really free?
Yes: MIT licensed, free for personal and commercial use, no paid tier.
Which systems?
macOS 11+ (Apple Silicon, Intel), Windows 10/11 (x64, ARM64), Linux (x64, ARM64; AppImage and deb).
Is it a MobaXterm alternative?
For daily SSH, files, RDP/VNC and tunnels, yes, on all three systems; it imports MobaXterm sessions. A built-in X server on Windows is not there yet.
Where do passwords go?
Into the system keychain, only after a login worked, optionally sealed with a master password. Never into exports or logs.
Why the security warning?
The installers are not code-signed with a paid certificate yet. Check the download against SHA256SUMS.txt, or build from source.
