Paneflow is a cross-platform terminal multiplexer built for agentic
CLI workflows - Claude Code, Codex, OpenCode, and any other agent that
speaks plain shell. Split panes, persistent sessions, dev-server port
detection, and zero-config theming, all in a native GPU-accelerated
app that boots in under 200 ms.

  Paneflow ships signed binaries for **macOS** (notarized `.dmg`, Apple
  Silicon) and **Linux** (`.deb`, AppImage, tarball, x86\_64 and ARM64).
  The buttons above grab the recommended format for each OS; the per-OS
  guides below cover every other path.

## What runs on the inside [#what-runs-on-the-inside]

* **Pure Rust** + [GPUI](https://www.gpui.rs/) - the same framework Zed runs on.
* **Native VT emulation** via `alacritty_terminal` (crates.io 0.26).
* **Native PTY** via `portable-pty` - same code path on Linux and macOS.
* **JSON-RPC IPC** at `$XDG_RUNTIME_DIR/paneflow/paneflow.sock` for headless scripting.
* **Sub-200 ms cold start** and sub-4 ms keystroke-to-pixel on the latency probe.

## Install with your AI agent [#install-with-your-ai-agent]

Already running Claude Code, Codex, OpenCode, or another agentic CLI?
Hand the install over - the prompt below tells your agent to read this
documentation, detect your OS, and walk the install one confirmation
at a time.
