Herdr: the runtime coding agents run on
![]()
Herdr is a server that runs in the background and holds the terminals of your coding agents (Claude Code, Codex, opencode, Cursor and the rest) without wrapping or replacing them: close the lid or drop the network and the agents keep working, and after a restart it brings the layout back and resumes their sessions. It shows which agents are working, idle or waiting on you, adds your other machines over SSH, and gives the agents themselves a CLI and socket API to split panes, start and prompt each other, and wait on one another. It is one binary for macOS, Linux and Windows, under the Apache 2.0 licence; the landing page's install and plugin counters are the company's own.
