# portable-pty

> portable-pty (v0.9.0, ~22.7M crates.io downloads) is the cross-platform pseudoterminal layer from the WezTerm terminal, published as its own crate. It starts a shell or program (cmd, PowerShell, bash, wsl.exe) and streams its input and output, so a Rust or Tauri app can pair it with a terminal screen such as xterm.js. It lives in the wezterm/wezterm repo, so the stars shown are WezTerm's. MIT, Rust only. A library for developers, not an end-user app.
