TermiSSH

The mobile terminal you've been waiting for. TermiSSH combines a professional SSH terminal, server monitoring dashboard, and a full-featured SFTP file manager into one complete iPhone app. Debug a production issue, deploy code, or check server health from anywhere. Works with Synology, QNAP, and other NAS devices for remote SSH access and file management.

Server Monitoring

Real-time server metrics at a glance — CPU load, memory usage, disk space, and system uptime directly from your iPhone.

• Live metrics — CPU load (1/5/15 min), memory usage, disk utilization, uptime • Auto-polling — refresh intervals (15s/30s/60s) • Concurrent checks — monitor multiple servers simultaneously with parallel SSH connections • Zero setup — reads metrics via standard Linux commands, no server-side software needed

Cloud Monitoring with Push Alerts — 24/7 watch (Pro)

Even with the app closed, TermiSSH cloud keeps checking your servers and pushes alerts when something goes wrong.

• Around-the-clock checks — monitoring never stops, even when the app is backgrounded • Push alerts — instant notifications on server down or check failures; consecutive-failure detection prevents false alarms • Recovery alerts — automatic notification when your server is back online • Custom checks — monitor any command output or port reachability with threshold alerts and ready-made templates

SSH Terminal

Full keyboard, real terminal — a desktop-class SSH experience on iPhone.

• Password and private key authentication — RSA 2048/4096, ECDSA P-256 • SSH key generation — generate key pairs directly in the app, no computer needed • True color terminal — SwiftTerm rendering engine with xterm-256color support • Custom keyboard toolbar — Esc, Tab, Ctrl+C/D/Z, PgUp/PgDn, Home/End • Pinch to zoom — adjust font size with a two-finger gesture • Quick commands and snippets — 60+ built-in commands plus your own custom library • Auto-reconnect — configurable keepalive and automatic reconnection

SFTP File Manager

Browse, upload, download, and preview remote files just like a local file manager.

• Full file operations — upload, download, delete, rename (supports recursive operations) • Package download — zip entire directories into a single file • Recursive search — search through every file in a directory tree • Text preview — code, logs, configs, Markdown — 40+ formats • Share sheet integration — send files from other apps directly to your server

SFTP is completely free in TermiSSH. No paywall, no limits.

Security and Privacy

• iOS Keychain storage — passwords and private keys stored in Secure Enclave • Host key verification — fingerprint validation against man-in-the-middle attacks • Face ID and Passcode lock — app locks when backgrounded, clears the terminal screen • End-to-end encryption — all traffic encrypted via libssh2 and mbedTLS • Zero analytics — no tracking SDKs, no crash reporters, no third-party services • No data collection — not even anonymous usage statistics

Productivity

• Saved servers — named profiles, icons, drag-and-drop groups • Group proxy — configure jump host / HTTP proxy for an entire server group at once • iCloud sync — keep your server list consistent across devices (Pro) • Import/export — share server configurations as JSON files • Quick commands — 60+ built-in snippets and unlimited custom commands
