Show HN: Relaymux, a tmux-based meta-harness for local coding agents

Relaymux, a tmux-based meta-harness for local coding agents, was released on Hacker News. The tool allows developers to run and track CLI agents via Telegram, iMessage, or CLI, with subagents operating in tmux windows. It aims to simplify multi-agent orchestration by avoiding overengineered solutions.

Hey HN, There’s been a lot of interest recently in meta-harnesses, loops, and multi-agent orchestration. Obviously, there are already a lot of good tools: Conductor, cmux, the native Codex / Claude Code apps, etc. For my own use cases, I’ve felt that the orchestration layer tends to feel overengineered. I mostly wanted a simple local harness i.e Pi for running and tracking CLI agents with the ability to hop in via tmux . Relaymux is my opinionated attempt at that. A few design principles: - The frontend is just Telegram / iMessage / CLI. If I want more visibility, I hop into tmux. - Subagents are normal interactive CLI agents running in tmux windows, usually with their own worktrees. - The harness owns the tmux session, so each longer task becomes a named tab/window. Subagents report back to the orchestrator via CLI when they’re blocked or done. Then the orchestrator just messages me on Telegram / iMessage - It works with any CLI agent that has an interactive terminal mode, so I don’t need special print-mode/non-interactive support. This means I don’t need to stress about the Agent SDK / claude -p billing limitations.
