Herdr

The pitch that landed for me is the boring one: a server that holds your terminals so you don't have to. Herdr 0.9 stitching local and remote machines into one TUI client with independent reconnects is the release that made the multi-machine story actually usable — before that, adding a workbox over SSH was the kind of thing you set up once and hoped never to touch again. Pick this when your day is several agents across several repos and you're tired of being the thing that keeps them alive. The blocked/working/idle readout per pane is the feature I'd pay for on its own; hunting through tabs for whoever is waiting on an answer is the real tax on parallel agent work, more than CPU or memory. The agent-driven API is genuinely different from tmux. Because the CLI and the socket are one surface, an agent can start a peer, prompt it, and wait on a blocked one rather than blasting keystrokes. That's the piece worth testing against your own workflow, and also the piece that takes a beat to trust. Pass if you run one agent at a time. Persistence and reattach buy you almost nothing when nothing is left unattended, and you'll be paying SSH setup costs for a feature you don't use. Pass too if what you actually want is orchestration — task routing, scheduling, model hosting. Herdr owns terminals, full stop. The closest comparison is your existing tmux config. If tmux plus a couple of scripts already does what you need, Herdr's gain is the agent-aware status layer and the remote machine merging, not raw multiplexing. That's a real gain, but not a free one — you're adopting a young runtime at v0.9.4 with Windows in beta. On cost: the runtime is Apache-2.0 and self-hosted, and Herdr's $6M seed led by Bessemer plus the Y Combinator batch means the company behind it is funded
