herdr web ui

Your herdr agents, in a browser and on your phone.

Read them as a chat, drop into the live terminal, and answer when they ask. The panes you already run in herdr, from any screen.

herdr plugin install devswha/herdr-web-ui

Try it in your browser firstThe app on a fictional session, no install. Nothing in it is live.

Then open http://localhost:7317. It needs a running herdr 0.9.0+, Bun 1.4+ and Node 18+, and it starts with herdr from then on. Run it from a checkout instead, or hand INSTALL.md to a coding agent.

Desktop: a Claude Code chat with its work folded, a Codex approval answered from the chat, the live terminal, and the command palette.
Phone: the session list, a Codex approval, the terminal with its key bar.

Nothing in between

  • herdr owns the sessions

    Claude Code, Codex, omp, omo, gjc and the rest keep running in herdr exactly as you start them. There is no wrapper command, no second daemon and no account. This app reads herdr's socket and attaches to its terminals.

  • One pane, every screen

    The pane in your herdr TUI is the same pane in your browser and on your phone, live in all of them at once. Nothing is stopped or handed over, and other Linux and macOS PCs join the sidebar over SSH.

  • Yours only

    It runs on your machine and listens on 127.0.0.1 by default. It sends nothing anywhere except GitHub, for its own updates, and your browser's push service, for alerts. Updates install in the background and roll back if the new build fails its health check.

The chat, the terminal, and the questions in between

The chat is built from the agent's own transcript, not from screen text. Each turn's commands, edits and progress fold into one block, the todo list stays pinned below, and the real terminal is one tap away for full-screen TUIs and raw keys.

Chat view of a Claude Code pane: the prompt, a folded "Worked for 2m 36s" block, and a Markdown answer with a code block and a link.
Chat. Prompts and Markdown answers with links, code and tables. Copy an answer as Markdown or plain text.
Terminal view of a shell pane: git history and a passing bun test run in the live herdr terminal.
Terminal. The same pane through herdr terminal attach, with herdr's scrollback, shared with your own TUI.
A Codex pane waiting for input: an "Allow command?" card for git push with its three options, answered from the chat.
Prompts. Approvals, questions and plan menus become cards. Tap an option, or type its number. The server checks that the menu is still current before it answers.

Every agent herdr runs

Every pane shows up with its live status, terminal and alerts. The chat view reads the agent's own session files wherever it knows where they are.

On your phone

Serve it over HTTPS to install it and get push alerts. Tailscale is the shortest route: the server stays on 127.0.0.1 and Tailscale adds an HTTPS address that only devices in your tailnet can open.

  1. On the PC that runs herdr, publish the app to your tailnet.

    tailscale serve --bg --https=443 http://127.0.0.1:7317

  2. Open that address on your phone and install the app.

    Safari: Share, then Add to Home Screen. Chrome: Install app.

  3. Tap the bell to turn on alerts for that device.

    You are told when an agent needs you or finishes. iPhone needs iOS 16.4+ and the home-screen app.

Your own Tailscale devices get in as you. Anyone else's device, or a LAN address, a public domain or a reverse proxy, is paired once with a code from Settings → Devices. Access and safety has the details.
