jmux

The terminal workspace for agentic development.

jmux launched on April 8, 2026 with 1 votes, #8,101 of 21,248 launches that month.

What it does

A terminal workspace for running AI coding agents in parallel. A persistent sidebar shows every agent session at a glance. Green dot means new output, orange flag means it finished and needs your review. One click to switch. Works with Claude Code, Codex, aider, or anything else. Built on tmux, runs anywhere: local, SSH, containers. Bring your own editor, your own tools, your own workflow. Nothing proprietary, nothing locked in.

Run ten coding agents on ten branches and watch one screen. Each agent gets its own ticket, branch and worktree. One sidebar shows which is running, which is stuck, and which is handed off. It runs on the tmux you already have.

Each one on its own ticket, branch and worktree. One sidebar shows which is running, which is waiting on a decision, and which is handed off. Ticket to merge request, in the tmux you already have. Five agents means five terminals to check, and all five are waiting on you. jmux gives them one rail to report on. Every frame below was captured from a running jmux: the real cells, colours and text. Scroll, and the window follows. Every session you have running, always on screen: branch, merge request, CI, and what its agent is doing right now. No hunting through tabs to find out who is working. When a twenty-session day gets loud, Ctrl-a f narrows the rail to Needs you or Active . The flag and…from jmux.build

  • 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…

  • jmux – tmux-based development environment for humans and coding agentsApr 2026 · github.com · ▲10

    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…

  • PrettyMuxApr 2026 · prettymux.com · ▲73

    I built PrettyMux as a native Linux terminal workspace for multitask workflows and keeping track of my agents. It’s a GTK4 app built on Ghostty/libghostty, with split panes, workspaces, vertical tabs, notifications, project-aware tabs (shows favicons/logo automatically), and an in-app browser so terminals and docs/tools can live side by side. I started it because I wanted something tmux-like for modern GUI workflows on Linux, but native and not Electron, there is cmux but only available on macos (prettymux compiles on windows and macos too but not tested for now there) It’s…

  • Dwm.tmux – a dwm-inspired window manager for tmuxJan 2026 · github.com · ▲101

    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.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
