Rmux – A programmable terminal multiplexer with a Playwright-style SDK
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…
Rmux – A programmable terminal multiplexer with a Playwright-style SDK launched on May 21, 2026 with 194 votes, #134 of 20,538 launches that month and more than 99% of that year's launches.
In plain words
Rmux is a terminal multiplexer built in Rust that offers both a tmux-compatible command-line interface and a typed Rust SDK for terminal automation. It runs natively on Linux, macOS, and Windows, eliminating the need for output scraping and sleep commands through structured snapshots and locator-style waits. Designed for developers and automation engineers who need programmatic control over terminal sessions, it combines traditional multiplexer functionality with Playwright-inspired testing and automation capabilities.

Warp, a Rust-based terminal2022 · warp.dev · ▲946Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…

cmux - Ghostty-based terminal with vertical tabs and notificationsFeb 2026 · github.com · ▲198I run a lot of Claude Code and Codex sessions in parallel. I was using Ghostty with a bunch of split panes, and relying on native macOS notifications to know when an agent needed me. But Claude Code's notification body is always just "Claude is waiting for your input" with no context, and with enough tabs open, I couldn't even read the titles anymore. I tried a few coding orchestrators but most of them were Electron/Tauri apps and the performance bugged me. I also just prefer the terminal since GUI orchestrators lock you into their workflow. So I built cmux as a native macOS app in…
PrettyMuxApr 2026 · prettymux.com · ▲73I 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…
Zxc – Rust TLS proxy with tmux and Vim as UI, BurpSuite alternative2025 · github.com · ▲106Ditch Burp Suite’s bloat for zxc, a Rust-built, terminal-based proxy that uses tmux and Vim to intercept HTTP/S and WebSocket traffic. It captures requests for debugging, security testing, or tweaking—fast and lean. # Key Features - Disk Wizardry: Stashes massive datasets on disk-100k+ entries without breaking a sweat. - Addons: Boost your workflow with default support for ffuf and sqlmap, or craft your own addons for extra fun. - Buffer Tweaks: Edit variables in a popup (e.g., b:host, b:scheme) in Interceptor/Repeater to twist requests. - Config Control: TOML files for global…
Tmux-IDE, OSS agent-first terminal IDEMar 2026 · tmux.thijsverreck.com · ▲88Hey 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…

Talanoa▲340Hi 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…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
