HostAtlas SSH is a modern, cross-platform SSH client built with Tauri 2 + React 19 + Rust. It syncs its server list from your HostAtlas account with a single OAuth login, and works standalone for any SSH connection you’d want to keep outside HostAtlas.

Features

• Multi-session tabs — many SSH connections in parallel with named tabs
• SFTP file browser — browse, upload, download files on remote servers
• Port forwarding — create SSH tunnels with a visual panel (local, remote, dynamic)
• Command snippets — save and organise frequently used commands
• HostAtlas sync — one-click OAuth login syncs your server list automatically
• Deep links — open SSH sessions via hostatlas://ssh/user@host URLs
• Terminal search — find text in terminal output (Cmd+F / Ctrl+F)
• Keyboard shortcuts — Cmd+T (connect), Cmd+W (close), Cmd+1-9 (switch tabs)

Note

Every SSH session is a direct connection from your machine to the server. HostAtlas is only the address book — traffic never proxies through the platform.

Install

Downloads from install.hostatlas.app/ssh-client/latest/:

Platform	File
macOS (Apple Silicon)	.dmg
macOS (Intel)	.dmg
Linux (x86_64)	.deb
Windows (x86_64)	.msi

The top-level https://install.hostatlas.app/ssh-client/version.json carries the full list under binaries[] (filename, size, sha256, url) and both folders publish a files.json sidecar for checksum verification.

Every release is also published as a GitHub Release.

Authentication (HostAtlas sync)

The SSH Client uses browser-based OAuth:

1. Click Login with HostAtlas in Settings
2. Your browser opens the HostAtlas authorization page
3. Click Authorize to grant server-list access
4. The app receives its token via the hostatlas://auth/callback deep link
5. The server list syncs automatically

The generated API key has the ssh:read scope only — it can view your server list but cannot modify anything. Revoke anytime from Settings → API Keys in the HostAtlas dashboard.

Deep-link protocol

Open SSH sessions directly from your browser or other apps:

hostatlas://ssh/deploy@192.168.1.10?hostname=web-server
hostatlas://ssh/root@my-server.com

The desktop CLI’s hostatlas ssh [server-uuid] command generates one of these deep links for the given server.

Keyboard shortcuts

Shortcut	Action
Cmd+T	Quick Connect
Cmd+W	Close current tab
Cmd+1-9	Switch to tab N
Cmd+F	Search in terminal
Ctrl+Scroll	Adjust font size

(On Windows and Linux, Ctrl replaces Cmd.)

Tech stack

Layer	Technology
Frontend	React 19, TypeScript, Tailwind CSS 4, xterm.js 6
Backend	Rust, Tauri 2
SSH	russh 0.46 (pure-Rust SSH implementation — no system ssh binary dependency)
SFTP	russh-sftp 2.0
Terminal	portable-pty 0.8
Auth	OAuth via deep link (hostatlas://auth/callback)

Security

• SSH connections are direct — PTY → SSH, no proxy, no cloud round-trip
• Auth tokens stored locally only — never synced anywhere
• SFTP uses a pure-Rust implementation (russh) — no external SSH tool dependency
• Deep-link payloads validated and sanitised against injection attacks
• Host-key verification uses the accept-new policy — new hosts are added on first connect, changed keys prompt for review
