spymux – Spy on your tmux panes

I had motivation for writing this after I kept switching back and forth between agents to see if they've finished what they were working on (and I couldn't find a similar tool out there). I'd imagine it can be useful for other scenarios as well, e.g. tracking multiple build/test jobs over multiple windows. Still a work in progress, but I thought I'd share :)

In plain words

Spymux is a tool that monitors tmux panes without requiring manual switching between them. It allows users to track the progress of multiple tasks running in parallel, such as agent processes, build jobs, or test runs across different windows. The tool addresses the need to check on long-running operations without constantly navigating between panes, making it useful for developers managing concurrent workloads in terminal environments.

spymux is a terminal user-interface for simultaneously watching all of your open tmux panes. Why? I pair program a fair amount with tools like codex , and I run them in different projects (windows) at the same time. I'd like a tool that gives me a clear view into what the agents are doing, without having to switch between them. spymux should run on any system, including Linux, MacOS, and the BSDs. Pre-built binaries for Linux, MacOS, and Windows can be found on the releases page . spymux 0.1.3 A centralized view for all of your tmux panes Usage: spymux [OPTIONS] [COMMAND] Commands: resume Resume a spymux session in another directory help Print this message or the help of the given…from github.com

    Hey, HN! With all recent agentic workflows being primarily terminal- and tmux-based, I wanted to share a little project I created about decade ago. I've continued to use this as my primary terminal "window manager" and wanted to share in case others might find it useful. I would love to hear about other's terminal-based workflows and any other tools you may use with similar functionality.

    Hey HN, Small OSS project that i created for myself and want to share with the community. It's a declarative, scriptable, terminal-based IDE focussed on agentic engineering. That's a lot of jargon, but essentially its a multi-agent IDE that you start in your terminal. Why is that relevant? Thanks to tmux and SSH, it means that you have a really simple and efficient way to create your own always-on coding setup. Boot into your IDE through ssh, give a prompt to claude and close off your machine. In tmux-ide claude will keep working. The tool is intentionally really lightweight, because I think…
