Programmable SDK for scripting and testing
“Having an actual library for interactions that isn't just a wrapper around the CLI seems like it would be a huge improvement”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “And it enables integration testing too. I hope it will foster the release of more cool TUIs.”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “you can finally do acceptance/integration tests on your terminal user interfaces”

Windows support and async SDK
“windows support, and the sdk. native async "wait until" something appears on your terminal, so you don't spam send-keys”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “windows support + async + public sdk. You can rewrite zellij with rmux, but not the opposite.”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “rmux is a faster and more elegant clone of tmux + windows support + programmable sdk”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” Landing page and demos
“I found the landing page covering exactly what the product does, with nice demos and examples.”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “I genuinely loved your landing page.”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “the site is actually quite cool”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” Faster than tmux or zellij
“rmux is much faster than tmux or zellj, I did some internal benchmark and it's promising.”

What people warn about
Each mark is one comment
Website looks AI-made, flashy or inaccurate
“The paragraph on the website inviting us to switch to rmux from tmux claims that tmux is programmed in C++.”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “Not to mention those absolutely horrible scroll animations.”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “The website is a little too obviously made by Claude.”

tmux or zellij already do this
“everything mentioned in the readme is already trivially possible with tmux or zellij”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “not sure why I would use this above tmux which works well”
Comment from 21 May 2026 in “Show HN: Rmux – A programmable terminal multiplexer with a Playwright-style SDK” “there are alternatives such as zellij and rmux”
