SigilTTY vs CekTerm

SigilTTY is a native terminal for iPhone, iPad, and Mac — an SSH client built for working with coding agents. Attach to the agents running on your own servers, see which are working and which are stuck, get alerted the moment one needs you, and answer out loud. Shells, SFTP, tunnels and keys are all here too, synced through iCloud. SigilTTY contains no language model and no chatbot. The agents are programs on your own servers — SigilTTY is the terminal you reach them with. YOUR AGENTS, ANYWHERE • Attach to the coding agents herdr runs on your servers, each with a live status dot • Every agent on every server in one list — in the sidebar on iPad and Mac, in its own tab on iPhone • Get alerted when an agent is blocked or done — on iPhone and iPad even with the app closed, end-to-end encrypted • Reply by voice: on-device, or with your own Volcengine, iFlytek or compatible speech-to-text key. The text is typed in for you to check — it never sends itself • Paste or drop files into the terminal to upload them • Requires the open-source herdr 0.8.0 or later on your server SERVER MONITOR • CPU, memory, disk, network and top processes for all your servers on one page • Sort any column and end a runaway process • Linux, macOS and FreeBSD — nothing to install on the server A REAL TERMINAL • GPU-accelerated rendering powered by Ghostty • Tabs everywhere; splits and broadcast input on Mac • Output highlighting for Cisco, Huawei/H3C and other network gear • Hundreds of color themes, with the whole app following your theme • CJK font selection and one-tap command snippets CONNECT • SSH with password, private key or hardware security key • Telnet, and USB serial console on Mac • Jump hosts and Quick Connect FILES & TUNNELS • SFTP file browser with preview • ZMODEM (sz / rz) right in the terminal • Local and remote port forwarding, SSH agent forwarding SECURITY • Credentials stay in the Keychain; optional Face ID / Touch ID for keys • FIDO2 security keys over USB-C or NFC, tested with YubiKey • Host key verification; a remote host must ask before touching your clipboard • Key Handoff: move a key to another device over your LAN, end-to-end encrypted • No ads. No analytics. No tracking. SYNC • Servers, folders, snippets, keys, known hosts and agent records sync with iCloud • English and Simplified Chinese Free to download. Feedback: support@sigiltty.com

Carry your remote tmux session in your pocket. Close the app; the work keeps running. CekTerm is an SSH terminal for iPhone and iPad. It never owns your work — the real thing is the tmux session on the remote host, and the app is just a client you can throw away and reattach at any time. So switching apps, running out of battery, losing signal underground, even swiping the app out of the multitasking list: that build, training run, deploy or AI agent is still going. Open it again and the screen picks up exactly where you left off. Features • Sessions live in remote tmux Disconnects, app switches and dead batteries do not matter — come back, attach to the same session, and the half-finished work is still there. • Local scrollback, scrolling never hits the network tmux control mode returns a linear output stream, so history is stored on the phone and scrolling back feels like scrolling any other page. • Session names stay on the phone If the remote tmux session is gone, its entry remains in the list — one tap rebuilds it with the same name and settings. • Keys are generated on the device Ed25519 or ECDSA, straight into the Keychain — no copying a private key across machines, which is where keys usually leak. • Input built for a phone A dedicated row for Ctrl/Alt/arrows, frequent commands as reorderable tabs, and floating Enter and clear buttons you can drag anywhere. • An exit key that reads the context It asks the remote what is running first: q for less, Ctrl-D for python, Ctrl-C twice for an agent — and for vim it asks whether to save. • Pick the remote folder and shell Browse the remote directory tree while creating a session; the shell list is read from that host, so you do not have to remember paths. • Upload files over SFTP Send several files at once to any remote folder and leave the page while it transfers. The file only appears at its final path once complete, so an interruption never leaves half a file behind. • Voice input Speak a line, get text, review it before sending — or run it straight away. Long commands are painful to type on a phone. • Six interface languages and multiple themes The interface language is independent of the system setting, and the terminal has six colour schemes of its own. Security • Private keys, passphrases and passwords live in the Keychain, readable only after the device is unlocked, and never leave this device via iCloud Keychain or encrypted backups. • Host keys use TOFU: the key is recorded on first connect and must match exactly every time after; a mismatch aborts the connection and shows both fingerprints. • Biometric lock: protect the app with Face ID or Touch ID and lock it the moment it goes to the background. • Remote clipboard reads are refused: OSC 52 is implemented for writing only and never answers a read query. • Settings export contains no private keys or passwords — those stay in the Keychain. What you need A remote host you are authorised to log into, with tmux installed (Linux or macOS). Please use Ed25519 keys: RSA private keys can no longer authenticate against OpenSSH 8.8 and later. This app does not try to be a full SFTP browser or a port-forwarding tool — a desktop SSH client is better at those. It focuses on one thing: watching a long-running session from a phone.
