# Boo terminal multiplexer

7 Hacker News commenters recommended Boo terminal multiplexer and 6 criticized it, November 2025 to November 2026. It was recommended in 3 of 13 months.

**Verdict:** People like its clean backend built on libghostty, which keeps saved sessions matching what the terminal shows, and its creative mix of ideas. Critics question the Godot choice and find the features not novel.

## Why people recommend it

- Libghostty backend keeps saved state accurate (2 comments): "boo swaps that layer for libghostty-vt, Ghostty's VT core, so the saved state matches what your terminal would actually display" ([source](https://news.ycombinator.com/item?id=48497026)) "Really dig the minimal approach here. Swapping the backend to libghostty is exactly the kind of clean architecture we need." ([source](https://news.ycombinator.com/item?id=48498355))
- Creative, inspired use of a game engine (2 comments): "branching out and using something like a game engine for something like this is a fairly inspired choice" ([source](https://news.ycombinator.com/item?id=49666391)) "this is a very non-obvious, creative mashup of things that i directly found inspiring" ([source](https://news.ycombinator.com/item?id=49666468))
