Acheron
Your other computers

Every machine,
one canvas.

Agents running on your desktop at home, a Linux box under the desk, or a studio Mac can all be opened from the computer in front of you. Pair once with the same code you use for the phone, then open that computer’s workspaces in a window of their own. The agents keep running where they are; this computer shows them and types into them.

Work there, from here

Type into any session, move and resize panes, rename and close them. Start a new shell or agent with + New session: it runs on the other computer, in its folders, with its installed tools. Changes on either side show up on the other within about two seconds.

Mac and Ubuntu, both ways

A Mac can open an Ubuntu machine’s sessions and the other way round. Each computer keeps its own fleet: nothing is copied or merged, and closing a pane remotely never stops its agent.

Connected the way you choose

Pair on the same network. After that, Acheron goes straight to the other computer when it can reach it — at home, at the office, or over Tailscale or your own VPN — at no cost. Reaching it from anywhere else, with nothing to set up, is part of Acheron Connection.

Encrypted end to end

Every connection is SSH between your two computers, with this computer’s key installed at pairing and the other computer’s key pinned on first use. A relay in between only ever carries encrypted traffic.

What stays on the other computer

Model provider presets, SSH sessions and new workspaces are still created on that computer itself. Its agents need it to stay awake and online.

Early days

Remote windows are new. Expect rough edges, and tell us what breaks.
