jmux – tmux-based development environment for humans and coding agents

I've been a tmux user for years. When I started running 5-10 Claude Code sessions in parallel, I tried the tools that are out there: Conductor, cmux, the GUI orchestrators. None of them felt right. They either wanted me to leave tmux entirely for a 100MB+ Electron app with its own editor and Git workflow, or they were thin wrappers that didn't solve the actual problem: I need to parallelize my entire development environment, agents, editors, servers, logs, and keep track of all of it. So I built jmux. It turns tmux into a parallel development environment. Every session, every agent, every…

In plain words

jmux is a tmux-based tool that enables parallel development environments for running multiple AI coding agents and processes simultaneously. It keeps sessions, agents, servers, and logs organized and navigable within a single terminal interface, allowing developers to manage 5-10 concurrent Claude Code sessions without switching to external applications. Built for tmux users and those coordinating multiple AI agents, jmux stands out by preserving the native tmux workflow while adding visibility and navigation across parallel development tasks.

  • Tmux-IDE, OSS agent-first terminal IDEMar 2026 · tmux.thijsverreck.com · ▲88

    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…

    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.
