herdr-web-ui, a browser and phone client for Herdr, lets a developer approve coding agents from a mobile home screen

A phone screen is the smallest surface a coding agent could notify, and the most common one a developer carries. A new client called herdr-web-ui pairs a browser and an installable phone app to the Herdr daemon so that approving the agent's next step is a tap on the lock screen rather than a round trip to the laptop.

The client is on GitHub as devswha/herdr-web-ui, released under MIT, and had 402 stars at publication. It is an independent client, not an official Herdr release, and the README says so. The repository was created on 17 September 2026 and had been pushed to within the hour at publication.

What the client puts in a browser tab

The home view lists each agent pane with a chat on one side and a live terminal on the other, so a developer can see what the agent typed and what it got back. The agent panes include every one Herdr already supports, which the project description names as Claude Code, Codex and others, with the same session mirrored to the browser and the phone at once.

The phone-first parts are the point of the project. A developer takes a screenshot on the phone, attaches it to the chat, and asks the agent to fix what is in the picture. The browser can be installed as a progressive web app, so the client sits on the home screen next to the camera and the inbox. Approvals and prompts arrive as web push notifications, so the laptop stays shut until the developer wants to open it.

What it adds to Herdr

Three capabilities are specific to the client rather than inherited from the daemon. SSH to remote PCs is set up through the client, which installs a bridge on the remote machine and joins its terminal into the sidebar beside the local agents. Speech-to-text input is wired into the chat box so a developer can speak the next prompt rather than type it on a phone keyboard. The notification channel is the browser's own web push, which the README notes works through the installed PWA on iOS and Android.

Freshness and traction

The repository is fresh enough that a reader should expect loose edges. At publication, 14 issues were open against 15 open pull requests, and the independent status means the maintainer cannot change the Herdr daemon itself. The traction, 402 stars in roughly two weeks on a repository that solves a well-defined missing piece of a popular daemon, is the signal that justifies the item.

The practical read for a team already running Herdr is that the laptop was the limit. Agents were running in the background on a workstation and the only way to approve a step was to walk to it. A client that mirrors the terminal to a phone and sends a push when a prompt is waiting means the evening's work no longer stalls when the developer is away from the desk.
