the agent runtime
Run them anywhere. Leave them running.
Herdr is the runtime your coding agents live on — laptop, desktop, or a box you rent. It holds real terminals open so the work survives the lid closing, and gets you back in from anything with a keyboard.

❯ make the herdr.dev hero mock look exactly like real claude code
● Ha. I read the real pane over the socket — the mock was on v2.1.168, Claude Code is v2.1.198 now. Missing the logo block and the whole rate-limit row.
● Plan:
· index.html — swap ✻ for the real ▐▛███▜▌ mark, bump the version
· css/style.css — coral bypass line, add the 5h / Week bars

This is src/main.rs — the entry point for herdr. Here's what it does:
1. Arg parsing — session::configure_from_args, then remote args for the SSH bridge.
2. Subcommand dispatch — server, client, update — each returns early.
3. Session mode — auto_detect_launch() connects to a running server or spawns one.

• Checkpointing works, so the job resumes from the last committed offset instead of restarting. The backfill in the next tab has been running for six hours and is unaffected by your laptop.
• Next I can add the p95 lag alert to the nightly run. Want that?

A real session: three workspaces, four agents, two of them mid-task. Nobody is attached to any of it right now — that's the point. Click an agent in the sidebar, it's a live layout, not an image.
01
Always running. →
Herdr isn't an app you keep open. It's a server running in the background, and the terminals live inside it. Close the lid or drop the network and the agents keep working; restart the machine and Herdr brings the layout back and resumes their sessions.
02
You never hunt for the stuck one. →
Herdr reads every pane and marks each agent working, blocked or idle. When one stops and needs an answer it says so, so you don't go pane by pane looking for whoever is waiting on you.
03
Agent-native. →
The CLI and the socket API are the same surface agents drive. They split panes, start each other, prompt each other, and wait until another agent is genuinely blocked instead of firing keystrokes and hoping.
04
Runs what you already run. →
Claude Code, Codex, Cursor, opencode, Grok and the rest. Herdr doesn't wrap them or replace them, it just owns their terminals — one binary, macOS and Linux, Windows in beta.

Where do agents run while you sleep? →
The answer is redacted for now. Read where Herdr is going in the Y Combinator announcement.
Give them somewhere to live.
One command, and nothing else about your setup changes — the agent CLIs you already run keep working exactly as they did, except now they don't stop when you do.
