In their own words
Herdr
Herdr is a background runtime for keeping coding agents’ terminal sessions available when you move between machines. It brings workspaces, tabs, panes, and agents into one terminal interface, with status labels that distinguish working, blocked, and idle agents. Herdr says it detects 22 agent command-line tools out of the box, including Claude Code, Codex, Cursor, OpenCode, Grok, Copilot, and Hermes. Panes and processes continue running when a client detaches, and saved layouts can be restored after a server restart. Integrations can report session identities for resuming after a restart, and some also report agent state. You can add SSH-accessible machines and view their workspaces alongside local ones. The runtime includes a local socket API and CLI for scripts, tools, and agents. It is free under the Apache License 2.0 and runs on macOS, Linux, and Windows. Pane screen history is off by default because terminal output may include sensitive information. Herdr Cloud is described as coming soon.
