Herdr 0.9 Introduces Multi-Machine Management for Agents

Multi-Machine Management Arrives in Herdr 0.9

Herdr, a tool with over 700,000 downloads and nearly 1,000 plugins, has released version 0.9, which introduces the ability to connect and manage agents across multiple machines. Previously, each machine required a separate Herdr client, making it difficult to oversee agents running on different remote servers or local setups.

Addressing User Needs for Remote Agent Control

The update responds to user demand for a unified interface to control agents, especially as more users run agents on dedicated remote machines (like VPS or Mac minis) rather than their primary laptops. This shift allows agents to run for extended periods without requiring the user's local machine to remain active. Community workarounds existed, but Herdr itself did not natively support this functionality.

Architectural Changes for Client-Side UI

Implementing multi-machine support required a fundamental change in Herdr's architecture. While previous versions rendered the entire UI on a single server, Herdr 0.9 now renders the outer UI on the client. This separation allows the client to integrate independent servers, each managing its own sessions and terminal views, into a single terminal user interface. This change also lays the groundwork for future performance improvements by further decoupling the client from the runtime.

Connecting Remote Machines

With Herdr 0.9, users can connect to remote machines by providing an SSH target. Once connected, the remote machine's workspaces, tabs, and agents become accessible alongside local ones within the same Herdr client interface. This eliminates the need to switch between multiple terminal tabs to monitor agents running on different systems.
