Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK

📝 Discussion Summary (Click to expand)

1. AI‑generated polish is accepted but still scrutinised

“The video of the front page is assisted by AI, I am not a VFX artist; please check rmux code architecture instead, I put a lot of efforts on it.” – shideneyu

“I genuinely loved your landing page… it’s obviously AI assisted but I interpreted it as a nod to itself on that and really appreciated it.” – powvans

The community notices the AI‑assisted aesthetic (the “pulsing green dot”, the blue crab) and reacts with both skepticism and appreciation, but they care more about the underlying effort and functionality than the method of creation.


2. Technical merits & design choices set RMux apart

“rmux is much faster than tmux or zellij, I did some internal benchmark and it’s promising.” – shideneyu

“You can rewrite Zellij entirely with rmux; it’s an engine, not just a front‑end.” – shideneyu

“I thought I was too zealous… separating responsibilities for session and window management would have diverged too much from tmux.” – shideneyu

These points highlight speed, an async‑wait SDK, window‑level programmability, and the decision to stay close to tmux’s API while adding Windows support and a Rust‑native engine.


3. Need for programmable multiplexers driven by agents/AI> “The Playwright‑style snapshot/wait layer is the interesting part to me… stable pane IDs plus explicit waits should make replay and debugging much saner.” – eddyaipt

“Same! TUI are becoming more and more mainstream so there is a need for automated multiplexing, not used by humans but by programs (and agents).” – shideneyu

“Windows support, and the SDK. native async ‘wait until’ something appears on your terminal, so you don’t spam send‑keys.” – shideneyu

The discussion converges on a growing demand for a terminal multiplexer that can be driven by scripts and AI agents, with stable identifiers and async coordination as the key differentiators.


🚀 Project Ideas

TerminalPlaywright

Summary

  • A VS Code extension that records, visualizes, and asserts terminal sessions, providing deterministic waits and pane snapshots for reliable automation.
  • Core value: turn flaky send‑key scripts into production‑ready test suites with one‑click debugging.

Details

Key Value
Target Audience QA engineers, DevOps automation specialists, CI/CD pipeline creators
Core Feature Session recording with frame‑step, explicit pane/window IDs, automated “wait‑for” conditions
Tech Stack TypeScript/React front‑end, Node.js backend, Playwright core, WebSocket for live terminal
Difficulty High
Monetization Revenue-ready: $29/mo per seat (team licensing)

Notes

  • Direct quote: “The Playwright‑style snapshot/wait layer is the interesting part to me… Stable pane IDs plus explicit waits should make replay and debugging much saner.”
  • Addresses frustration with “grep+sleep loops” and makes terminal automation production‑ready.

SkillVault Marketplace

Summary

  • A community‑driven marketplace for terminal multiplexer configuration “skill” files, enabling easy reordering, layout sharing, and versioned testing.
  • Core value: reuse proven pane layouts across tmux, rmux, and Zellij with one‑click install.

Details

Key Value
Target Audience Power users, automation scripters, remote‑SSH workflow engineers
Core Feature Upload/download JSON skill manifests, CI‑tested layout validation, marketplace with rating
Tech Stack Rust backend (actix‑web), PostgreSQL, React UI, WebAssembly for manifest parsing
Difficulty Medium
Monetization Revenue-ready: 10% transaction fee on premium paid layouts

Notes

  • Community discussion highlighted need for “CLI that a coding harness can use to drive it” and “reorder panes via a skill file” (e.g., “last week I vibecoded a plugin…”).
  • A marketplace would let users adopt polished layouts without reinventing them, accelerating adoption of advanced multiplexers.
