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
