Herdr now has a desktop app — no longer just "tmux for agents"
Herdr — a runtime for coding agents
https://herdr.dev/tui/
Herdr is a runtime for coding agents that doesn't just wrap Claude Code, Codex, OpenCode, or Pi — it owns their terminals. The classic Herdr isn't going away, but it's now a separate product with its own server: agents started in the TUI don't show up in the app, and vice versa.

On October 29, Herdr announced two things at once: the new herdr-core and a native desktop app built on it. Agents live in herdr-core, a small server on the machine, so closing the window or updating doesn't kill the work. Agents can control other agents. After a herdr-core restart, processes aren't restored — only the layout.
Herdr is interesting because it turns the UI into files and lets agents control each other. It's no longer "tmux with statuses" but an attempt to build a work environment an agent can rewrite for itself. Telemetry in releases is on by default (Settings → Privacy).
Layouts aren't themes but full windows with their own logic. Herdr 98 ships in the box. The community shares its layouts: Pasture (agents as sheep; a blocked one jumps with a speech bubble), Mission (green mission control), Board (cards: needs you / working / done / idle), Call, Threads. Importantly, someone else's layout can read files, access the network, and run processes.
Quick tour
shows that the desktop is not just a pretty TUI but a construction kit. Light theme, importing old TUI settings, adding a file tree mod during setup, opening a space.

The author shows that mods can be installed right away. You can ask Herdr to switch to tmux bindings. The author tells the agent: "split panel vertically and start two Codex agents; add another tab with two Claude agents" — the agent splits the pane, opens a tab, and starts the agents itself. Agents communicate through a bridge; the lead agent delegates to workers; you can sort by priority/space, drag panels, and split horizontally or vertically.

A "harness for your harnesses" that doesn't look like vibe-coded slop. Convenient "everything is a pane": you can keep an SSH session in one pane and ask an agent in another to diagnose the system, and it doesn't pull your SSH keys into the harness; agents from different vendors can review each other; UI customization: "told it to add a feature, and it reloaded."
Criticism: TUI and app are fragmented, old sessions weren't picked up, keybindings are different; no built-in browser; on Windows there's no proper installer/uninstaller; some found the app didn't detect Claude Code or showed empty panes after a restart.
