Claude Desktop remote.
Point the Claude desktop app at your box over SSH. The connection rides Prized's tunnel and a restricted device key that Prized installs for you, so there is nothing to configure on the box.
Why this needs no setup
Claude Desktop connects with its own SSH client, which honors your SSH config but does not present the SSH certificates Prized's terminal ssh authenticates with. Prized closes that gap: prized login registers this machine's SSH public key with your workspace, and every box accepts it as a restricted fallback. Terminal ssh never uses the fallback.
Connect the box
- Log in once on this machine (
prized login, part of the normal quickstart). Boxes pick up the device key within seconds. - In Claude Desktop, add the box as an SSH host by its hostname, for example
box-3fa9. The stanza Prized installs supplies the tunnel and the key; if the app asks for an identity file, use~/.config/prized/id_prized.
ssh box-3fa9
# confirms the connection from a terminal firstWhat the fallback key can do
The key the app authenticates with is deliberately narrower than a certificate:
| Fallback key (desktop apps) | Certificate (terminal ssh) | |
|---|---|---|
| Run commands, transfer files (SFTP) | yes | yes |
| Interactive terminal (PTY) | no | yes |
| Port forwarding | no | yes |
| Works outside your Prized tunnel | no | no |
The key is accepted only from inside your authenticated Prized tunnel, so a copy of the key file is useless on its own.
Removing a device
Delete the device's CLI token, or remove the member from the workspace; every box drops the key within seconds. A device silent for 45 days ages out on its own and re-registers when it next connects.
Caveats
- Wake the box first. The app's plain
sshdoes not wake a suspended box. Resume it from the dashboard or runprized sshonce, then connect. - The app stops when your machine sleeps. For an agent that keeps working with the laptop closed, run Claude Code on the box in a session instead.
- Password prompt? The box has not synced the key yet: make sure
prized loginran here, give it a minute, retry;prized doctorchecks the rest.

Codex remote
Add your box as an SSH host in the ChatGPT desktop app and Codex runs its tasks on the box, with every edit syncing back to your Mac as it lands. One command sets the connection up.
Boxes
A box is a dedicated Linux machine in the size you pick, from Nano to Extra Large. Create and manage boxes from the CLI or the dashboard; connect to them with the CLI.
