| Product | Herdr is a background runtime that keeps coding agents’ terminal sessions running so users can return to them from another machine. | Plux is a lightweight Unix-first terminal multiplexer implemented in Rust. |
| Remote access | Users can add remote machines over SSH and see their workspaces and agents alongside local ones. | Remote attach uses SSH as an encrypted bridge and requires a compatible Plux binary on the server. |
| Support | The maker’s site links to a Discord community and lists [email protected] as a contact email. | The README asks issue reporters to include a reproduction command, TERM, terminal size, shell, OS, and PLUX_DEBUG output. |

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.
