Herdr vs WMUX

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.

WMUX is a terminal multiplexer that keeps local terminal workspaces alive when a terminal client disconnects. Its persistent server manages sessions, windows, panes, terminal state, layouts, options, commands, paste buffers, jobs, and clients. That scope is intended for shells, servers, logs, builds, agents, and project work. Users can split panes left or right, or top or bottom, navigate among them, and zoom a pane. WMUX creates a default configuration file on first use, with commands to inspect its path, contents, and effective configuration. It runs on Linux, macOS, and Windows; Windows uses native platform mechanisms without a POSIX emulation layer. The software is free and MIT-licensed. Windows ARM64 builds and package-manager repositories are not currently provided. Release archives have SHA-256 sidecar files, and GitHub attestations can be used to verify build provenance. Its v1 binaries are not Authenticode-signed or Apple-notarized, so Windows SmartScreen or macOS Gatekeeper may show a trust prompt.
