Terminal, evolved

Everything you need to manage complex workflows in a single window.

Split anything

Binary tree split system. Up to 32 panes per workspace with drag-to-resize dividers, preset layouts, and directional focus navigation.

20 workspaces

Named, tabbed workspaces with session persistence. Your layouts and working directories survive restarts. Switch with Ctrl+1–9.

Zed’s terminal core

Same Alacritty fork and GPUI rendering engine as the Zed editor. GPU-accelerated, cell-by-cell paint with APCA contrast enforcement.

— Layouts

Splits that just work

A binary tree layout engine gives you arbitrary nesting. Split horizontal, vertical, zoom to fullscreen, or pick a preset. The layout adapts to your workflow, not the other way around.

  • -4 preset layouts
  • -Drag-to-resize dividers
  • -In-buffer regex search
  • -Undo close with Ctrl+Shift+T

— Context-aware

Dev server detection

Paneflow detects running HTTP servers in each workspace automatically. Frontend and backend ports are labeled and displayed in the sidebar. No configuration, no guessing which port is which.

  • -Auto-detect HTTP ports
  • -Frontend / backend labels
  • -Per-workspace service list
  • -Live git branch & diff stats

AI-ready

Built-in IPC server exposes a JSON-RPC 2.0 API over Unix sockets. Claude Code and Codex sessions are detected automatically. Script your terminal from any language.

  • -Claude Code & Codex detection
  • -JSON-RPC 2.0 via Unix socket
  • -Programmatic splits & text send
  • -Workspace management API

Everything you expect

24-bit color, IME input, drag-and-drop, regex URL detection, copy mode, and 6 hand-tuned themes with hot-reload. APCA perceptual contrast ensures readability across all themes.

  • -6 themes, hot-reload
  • -24-bit ANSI color
  • -Drag-and-drop files
  • -Regex URL auto-detection
