Herdr Releases Standalone Desktop App for Managing AI Coding Agents
Herdr launches a cross-platform desktop hub that decouples UI from execution, ensuring agent tasks persist through app crashes and offering status visibility via OSC 7501.
Open-source project Herdr has released a standalone desktop application on November 2, 2026, designed as a central hub for managing AI coding agents such as Claude Code and Codex. The app is now available for Linux, macOS, and Windows. According to German tech outlet heise.de, this new application is not merely a graphical frontend for the previous terminal multiplexer but a separate program built on the GPUI framework, relying on a new background service called herdr-core.
The key architectural shift lies in strictly separating 'display' from 'execution.' The user interface manages only the view, while actual terminal processes and agent operations are handled by herdr-core. This means that even if the main application window crashes, updates, or is closed, running AI agent tasks continue uninterrupted in the background. A corresponding terminal process terminates only when the user explicitly closes its tab or pane. After a system reboot, Herdr restores the previous window structure and working directories but does not automatically reconnect to interrupted agent sessions.
To accurately monitor the status of multiple parallel agents, Herdr introduces support for the terminal escape sequence OSC 7501. Agents or custom shell scripts can report their current state (working, blocked, done, idle) to the interface using simple printf commands. When a background agent requires user input or completes a task, the app notifies the user via sound and system notifications. Agents that do not support OSC 7501 can still run within Herdr but will not provide real-time status feedback.
