herdr, read at one pinned commit: strong on agent coordination, no record of cost or unattended work
A reviewer read herdr, a Rust background server that hosts coding-agent terminals, at a pinned 27 August commit and re-checked costs at v0.9.1. Its pane state model (working/blocked/idle) and CLI/socket API let agents hand off work and detect blocked peers. But the runtime records no per-run cost ledger and no history of unattended runs, leaving an eleven-round loop that burned ~650k tokens per round unnoticed.

AI Overview
- herdr is a ~41k-star Rust background server that owns coding agents' terminals, running Claude Code and Codex unmodified
- Every pane is working, blocked or idle, and the runtime surfaces the pane needing attention
- Agents drive the runtime via a CLI and socket API, letting an orchestrator hand work to another pane and wait on real blockage
- herdr records no per-run cost ledger, budget or spend trend; community plugins add pane cost badges and usage dashboards
- A build-review-fix loop re-read ~650k tokens per round for eleven rounds before anyone noticed the runaway
- herdr flags blocked agents but can't distinguish silent stops from finished jobs and keeps no record of unattended activity
- Reviewer puts hard caps on unattended runs and compares daily spend against a median; no maintainer has replied in the repo discussion

DHH describes running 16 parallel AI coding agents on Linux with Herdr
DHH shared his workflow for orchestrating up to 16 AI coding agents in parallel across multiple Linux machines using Herdr, a terminal tool that works like tmux with built-in agent notifications. The post offers practitioners a concrete pattern for managing many simultaneous agent sessions without losing track of them.

Multiplex: SSH/tmux/herdr terminal for Vision Pro and iPad
Multiplex is an open-source terminal app for visionOS and iPadOS that provides a multi-window SSH/tmux experience with first-class tmux integration, each session in its own window. It includes an Agent key bar, file viewer, and browser to support using Claude Code, Codex, and Pi for code review, and recently added support for herdr sessions. It solves the problem of needing a mobile terminal with robust tmux support and AI coding tool integration.

Concord: MCP/CLI for coding agents to coordinate and message
Concord is an MCP and CLI tool that lets coding agents like Claude Code, Codex, and Cursor communicate and coordinate. It allows agents to claim work, see what others are doing, and message each other live, preventing duplicated or conflicting changes. It solves the problem of parallel agents lacking task context, similar to giving a team a shared communication channel.

Developer open-sources HAR, a harness for multi-agent coding workflows
A developer open-sourced HAR, an agent-agnostic harness for running fleets of coding agents in parallel with deterministic validation, verifiable proof, and full observability. It addresses the lack of a standard way to run or verify a repository, which is scattered across README, CLAUDE.md, editor rules, and CI config. The tool aims to make multi-agent coding trustworthy and scalable.

Local dashboard for monitoring and managing AI coding agents in real time
Agentglass is an open-source local dashboard that watches all AI coding agents (Claude Code, Codex, Gemini) running on a machine, showing live fleet view, tool calls, token usage, cost per model, and tool latency. It surfaces stuck sessions, cost spikes, and pending approvals, and stores history in SQLite so data persists across reloads. It solves the problem of losing track of multiple agents across projects.
