A Agentum is open source — single binary, MIT licensed.
Agentum

Keep your agents running.

Agentum spawns Claude, Codex, and Gemini in tmux on a host you control — and keeps them shipping when you close the lid.

The loop

Spawn. Watch. Hand off. Repeat.

Agentum runs your agents in a loop on a host you own. Each pass spawns work, watches the terminal, and hands the next task on — while the laptop sleeps in your bag.

01 — Sessions

It spawns agents on a host you own.

One Rust binary wires tmux to a control plane. Spawn Claude, Codex, Gemini — or any CLI on PATH — over SSH, with a live terminal stream and an input bar. Loopback by default; expose to your LAN when you choose.

02 — Watchdog & skills

It watches every terminal and recovers.

A per-session watchdog reads the pane: Context low auto-issues /compact, crash signatures emit session.crashed. Every run that ships keeps its method as a reusable skill.

03 — Board

It hands work between agents.

Pull issues and PRs from GitHub and Linear onto an atomic-claim board, then hand them to agents. Optimistic drag, a 409 on contention — so two agents never grab the same task.

Mission control

Watch every session, live.

One pane keeps every session visible across local and SSH hosts — live status from the watchdog, context, and host CPU/RAM at a glance. Supervise the loop instead of babysitting twenty tmux panes.

Install

Two ways to run it.

Start with the desktop app — the full agent environment. Keyboard-first? It ships a daemon, a fast TUI, and a complete CLI too.

Agentum

The agent environment, native.

Workspaces, the board, channels, and live agent terminals — one app on macOS & Linux. The fastest way in.
