What It Does

Manages terminal workspaces to run and coordinate multiple AI coding agents in a developer-friendly TUI. Provides a terminal multiplexer-like interface that launches, groups, and monitors agent processes so you can run parallel coding assistants and inspect their outputs. Designed for reproducible agent experiments and quick manual orchestration of model-driven workflows in the terminal. See also reproducible agent experiments.

The Value Proposition

As teams prototype multi-agent coding workflows, having a clear, reproducible workspace matters for diagnosing failure modes and attributing behavior. Herd makes it easy to run many agents side-by-side, compare outputs, and keep an auditable record of sessions — a simple but powerful primitive for agent-to-agent evaluation and debugging. Until lightweight developer tooling like this exists, orchestrating and reproducing agent experiments remains ad hoc and error-prone. This supports agent-to-agent evaluation.

When to Use

Developers and researchers who want a terminal-native way to run, compare, and debug multiple AI coding agents and reproduce agent runs. This fits well with the Agent Registry Pattern for managing agents, and pairs with Dynamic Task Routing Pattern to orchestrate workflows.

Use Cases

Run parallel coding agents to compare generated patches and identify divergence
Reproduce and log agent sessions for postmortem analysis of failure modes
Manually orchestrate agent delegation and step through interactions in a terminal UI
