Sixel-tmux displays graphics even if your terminal has no Sixel support

In plain words

Sixel-tmux is a terminal multiplexer tool that enables graphics display in tmux sessions even when the underlying terminal lacks native Sixel support. Launched in 2021, it works as a dev tool for developers who need to view images or graphical content within tmux environments. The software bridges compatibility gaps by allowing Sixel graphics to function across terminals that wouldn't normally support them, expanding tmux's visual capabilities.

  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.

  Rmux – A programmable terminal multiplexer with a Playwright-style SDKMay 2026 · github.com · ▲194

  Author here. RMUX started from a frustration: I've used tmux for years and got tired of scraping output with grep and sleeps to automate anything. So I rebuilt the multiplexer from scratch in Rust, with a programmable layer on top. Two surfaces: a tmux-compatible CLI (~90 commands, your keybindings just work), and a typed async Rust SDK on the same daemon — stable pane IDs, structured snapshots, locator-style waits. The idea is Playwright-style automation, but for terminals. Native on Linux, macOS, Windows (real ConPTY, no WSL). Demos and docs at rmux.io. Happy to answer questions about the…

  Talanoa▲346

  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…
