Browser control for CLI coding agents
spawn
Run Codex, Claude, shell agents, and host tools across your laptop, workstations, and servers from one fast control plane.
$
curl -fsSL https://spawnd.dev/install.sh | shHost setup
One installer for macOS and Linux hosts.
The hosted script picks a prebuilt daemon for the host, falls back to a source build when needed, runs device-code login, and starts a user service where the OS supports it.
Prebuilt first
Downloads a prebuilt daemon binary before attempting any Rust or git build path.
User services
Uses LaunchAgent on macOS and user systemd on Linux with a background fallback.
CLI native
Runs your existing agent CLIs in real terminals with durable host registration.
Outbound only
Hosts dial the Spawn server over HTTPS/WSS, so no inbound SSH or agent ports are exposed.
Bring a host online.
Install the daemon, approve the device code, then start agents from the browser.
