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

Rmux is a new Rust-based terminal multiplexer announced on Hacker News.

It keeps tmux-compatible commands while adding a typed, async SDK for automation.

The design aims to replace brittle text-scraping with structured snapshots and pane IDs.

Rmux is positioned for Linux, macOS, and Windows, including ConPTY support.

The goal is more reliable, expressive terminal automation, similar in spirit to Playwright.
