Features

Everything an SSH client should be. Nothing it shouldn't.

A real terminal, real file transfer, and a keyboard-driven workflow — without ever leaving the sandbox.

Multi-tab terminal

Full xterm-256color, tmux-friendly, instant tab switching, in-place reconnect.

Side-by-side SFTP

A real file browser. Upload, download, rename, move, delete — never leave the app.

Trust-on-first-use

Server host keys are pinned on first connect and verified every time after.

Keychain-stored credentials

Passwords live in macOS Keychain. Never written to disk in plain text. Never in argv.

Sandboxed and notarized

Hardened Runtime, App Sandbox, network-only entitlements. Talks to nothing else.

No shelling out

SSH runs in-process via Citadel + SwiftNIO SSH. No /usr/bin/ssh, no sshpass.

Look inside

The whole workflow, in one window.

Why Ninja

Built by an engineer who got tired of Electron.

Ninja is a native Mac app — SwiftUI, hardware accelerated, retina-crisp, instant launch. Not a browser wearing a window frame. It does two things, terminal and file transfer, and it does them the way the keyboard-driven engineer expects.

There is no telemetry, no analytics SDK, and no subscription. SSH runs in-process. Passwords live in the Keychain. Host keys are pinned. Ninja connects to your servers and nothing else — and it never phones home.
