# Watch and control all your AI agents, from one app. Claude Code, Codex, OpenCode and Antigravity scatter across terminals and machines. Argus brings every session into one view, so you always know what's running, what's waiting on you, and what's done. ## One screen for every agent Every session from every machine in a single list, grouped by host and labeled by agent. Live status shows which are working, which are waiting on input, and which have gone idle, and the sessions that need you stay pinned to the top. ## See exactly what they did Open a session for the full transcript: prompts, replies, thinking, and every tool call. Fold the long parts or expand a single step, and tap any tool call to see the exact command it ran and what it returned, with model and token counts along the way. ## Jump in from anywhere Attach to a session's live terminal, watch it run, and type into it. Answer a permission prompt in place, review the code changes and git diffs it produced, or spawn, interrupt, and kill sessions without reaching for your laptop. ## Never miss a prompt Argus sends a push notification when a session needs your input, so a blocked agent doesn't sit idle while you're away. Notifications arrive even when the app is closed. ## Private and self-hosted Argus runs entirely on your own machines. You pair your phone directly to them over an end to end encrypted connection, so your prompts, code, and output never leave your control. Works with Claude Code, Codex, OpenCode and Antigravity in one list. Start on a single machine or scale to a fleet. _Source_: https://github.com/MunifTanjim/argus _Docs_: https://argus.muniftanjim.dev
