Herdr
What it is
Herdr is a background runtime that keeps coding agents’ terminal sessions available when you detach and return from another machine. It brings workspaces, tabs, panes, and agents into one terminal interface, labeling agents as working, blocked, or idle. 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 their processes continue running after a client detaches, and saved layouts can be restored after a server restart. Integrations can report session identities for resuming sessions; some also report agent state. You can add SSH-accessible remote machines and see their workspaces alongside local ones. Herdr offers a local socket API and CLI for scripts, tools, and agents. The runtime is free, open source under Apache License 2.0, and runs locally on macOS, Linux, and Windows. Pane screen history is off by default because terminal output may contain secrets and other sensitive content. Herdr Cloud is described as coming soon.
For and against
For
- Keeps panes and processes running after client detachment
- Shows working, blocked, and idle agent states
- Supports SSH-accessible remote machines
- Free runtime under Apache License 2.0
Against
- Herdr Cloud is not yet available
- Pane screen history is off by default
The verdict
Herdr brings agent sessions, workspace organization, and remote-machine access together in a free runtime. Consider its locally scoped persistence and the fact that cloud connectivity is still forthcoming when deciding whether it fits your setup.
Who it suits
Herdr suits people coordinating coding agents across terminal sessions and machines. It may also fit users who want local persistence, custom pane layouts, and an API or CLI for automation.
