Who it is forA developer on macOS, Linux, or Windows who already runs Herdr and wants a native client for it.
The problemHerdr sessions live in a terminal, so keeping track of several workspaces, worktrees, and agents at once is hard to see at a glance.
The outcomeThe Herdr UI app opens and shows your daemon's workspaces, worktrees, and agent status dots in one sidebar.
What you need first
- A Herdr daemon installed on your machine first, since this app is only its client
- macOS 14.2 Sonoma or newer with Homebrew, or a supported Linux distribution with glibc 2.39 or newer, or Windows with PowerShell
- For building from source: Rust via rustup, plus the Xcode command-line tools on macOS or the Visual Studio C++ build tools and Windows SDK on Windows
Steps
- Install the Herdr daemon from https://herdr.dev/ first, since the app only acts as its client.
- On macOS, run
brew install penso/tap/herdr-gpui, then runopen -a Herdr. - On Linux, run
curl -fsSL https://herdrui.dev/install.sh | sh. - On Windows, run
irm https://herdrui.dev/install.ps1 | iexin PowerShell. - Open the app and check that your workspaces and agents appear in the sidebar.
Prompt for your agent
Using the penso/herdr-gpui README, install the herdr-gpui client on <target-platform> with the matching command from the Install section, after confirming a Herdr daemon is already installed. Report the install command you ran and the version reported by the app. Verify that the app starts without installing or upgrading the Herdr daemon.
Caveat. The app is an unaffiliated client and does not install or upgrade the Herdr daemon, so the daemon must already be set up.
