Caret is a fast, native server console for developers and sysadmins. Connect to any Linux box over SSH from your iPhone, iPad or Mac — no agent on the server, no cloud middleman, no account required. — HERD YOUR AI CODING AGENTS — Run Claude or Codex agents on your own servers and manage them all from one inbox, grouped by status — working, waiting on you, or done. Read an agent's latest output, reply, review its exact code changes as a git diff, then drop into its terminal. Agents keep running even when the app is closed. — FULL SSH TERMINAL — A real interactive terminal powered by a complete VT/xterm engine. Run vim, htop, tail, or any program. Multiple tabs per server, automatic reconnection, and a mobile shortcut bar for Ctrl, Esc, arrows and pipes. Attach to tmux or zellij, forward local and remote ports, and pick from 17 themes. — LIVE MONITORING DASHBOARD — Watch CPU, memory, swap, disk, network and load average update in real time, with smooth on-device history. The Status screen aggregates every server into one board; tap through for per-core breakdowns, top processes and host details. Pull real server-side history from the host's own sar/sysstat records — even for time while the app was closed. Metrics come from reading /proc over SSH — nothing to install. Linux and macOS hosts. — DOCKER, EVERYWHERE — List containers across all your hosts at once, with live CPU, memory and network usage. Start, stop, restart, inspect and follow logs in real time. Build reusable Pod templates — a graphical docker run, or a Compose stack — and deploy them to any set of servers in one tap. — SFTP FILE MANAGER — Browse the remote filesystem, upload and download with live progress, and create, rename, move, compress or delete files and folders. Preview and edit text files right on the server. On Mac, drag files between servers or straight to and from Finder. — SNIPPETS & QUICK RUN — Keep go-to commands one tap away, and fire one command across many servers at once — with saved history of every run. — ASK AI, BRING YOUR OWN KEY — An optional AI assistant, one tap from any screen, that already knows what you're looking at — your metrics, containers, files or terminal. Ask what a process does, why load is spiking, or how to fix an error. Bring your own OpenAI, Anthropic or Gemini key; it stays in the Keychain and talks to the provider directly, with no Caret server in between. — KEYS, JUMP HOSTS & SECURITY — Passwords, keys and passphrases live in the system Keychain / Keystore, never in the app database. Manage SSH keys in-app, authenticate with passwords or keys, and reach private servers through a jump host (bastion), including multi-hop chains. Add an optional Face ID / Touch ID app lock. Turn on sync and your data — including credentials — travels only through your own private iCloud or Google Drive (end-to-end encrypted on Drive). — APPLE WATCH & WIDGETS — Keep an eye on your servers without opening the app. Home Screen and Lock Screen widgets show live CPU, memory and load; on Mac the same metrics sit in the menu bar. The Apple Watch app puts a read-only status board on your wrist — refreshed even while your iPhone is in your pocket. — BUILT FOR EVERY SCREEN — One native app for iPhone, iPad and Mac. On Mac it's a true desktop app — sidebar navigation, native density, multi-window and split-pane workspaces. Light and dark themes, and 14 languages. Caret is free, with server management, monitoring and Docker built in. A Premium upgrade unlocks the SSH terminal, SFTP editing, AI coding agents, the Ask AI assistant, server-side history, jump hosts, port forwarding and cloud sync — monthly, yearly or a one-time lifetime purchase.
