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
PaneFlow split layout with multiple panes and workspaces
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.

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.
