What It Does — A Unified Workspace for Agentic Development

Single Pane is a new macOS application designed as a "single pane of glass" for developers who have adopted an agentic workflow, particularly with Claude Code. It's built for those who have moved away from traditional IDEs to terminal-centric tools like Ghostty. The core problem it solves is the constant Alt+Tab (or Cmd+Tab) context switching between your terminal running claude code, your file explorer, and your markdown notes. It consolidates these into a single, tabbed application.

Its primary features are a full terminal emulator with advanced tab management, a dual-pane file manager, and a built-in markdown reader/editor. Crucially, it integrates directly with Claude Code via its hooks system to provide audio and visual notifications for agent events.

Setup — How to Install and Configure with Claude Code

Download and Install: Grab the latest .dmg from the GitHub releases page.
Enable Audio Hooks: When you enable audio notifications within Single Pane's settings, the app automatically registers URL scheme hooks in your Claude Code configuration. These hooks correspond to key events:
- SessionStart
- UserPromptSubmit
- SubagentStart
- Stop
- SessionEnd
- Notification
Each event triggers a distinct sound in Single Pane. You can preview and customize these sounds or mute specific events.
Start Working: Launch Claude Code sessions in Single Pane's terminal tabs. You can now manage files in the dual-pane explorer, edit CLAUDE.md or other notes in the markdown editor, and run agent commands—all without leaving the window.

When To Use It — Specific Use Cases Where It Shines

This tool excels in specific, high-context Claude Code workflows:

Horizontal tabs

Monitoring Parallel Agents: Use the grid view or split panes to run multiple claude code instances side-by-side. Watch one agent refactor a module while another writes tests, with audio cues telling you when each one completes a step or gets stuck.
Rapid File Operations: The dual-pane file manager (inspired by Total Commander) is perfect for moving generated code between source and test directories, or organizing project files while an agent is running. Drag-and-drop file paths directly into the terminal to feed file locations to Claude without typing.
Context-Rich Development Sessions: Keep your project notes, CLAUDE.md file, and the terminal output visible simultaneously. The clickable links and paths in the terminal output let you jump directly to a referenced file and line number (e.g., file.swift:42) in the editor pane.
Background Task Management: Enable macOS notifications for Stop and Notification events. You can browse Hacker News in another window, and a banner will appear when Claude finishes a long task or needs your input, thanks to the native hook integration.

Key Productivity Features

Hints Mode: Press Cmd+Shift+E to highlight every clickable URL and file path in the terminal. Type the hint label to open it.
Command Status Gutter: A visual indicator shows success/failure for each past command, making it easy to scan history for errors.
Find in Terminal: Search through all terminal output with Cmd+F.
Theme & Fonts: Includes Ghostty-inspired themes and a selection of monospace fonts.

AI Analysis

Claude Code users should evaluate if their workflow involves constant app-switching. If you're running `claude code` in a standalone terminal while managing files in Finder and notes in another app, Single Pane could consolidate that friction. Specifically, configure the audio hooks. The distinct sound for a `SubagentStart` or `Notification` event means you can look away from the screen while Claude works on a complex chain-of-thought, knowing you'll be alerted when intervention is needed. This turns Claude Code into more of a true background assistant. Use the dual-pane file manager to keep your project structure and generated code organized in real-time. Instead of letting Claude create a mess of files, you can immediately move, rename, or refactor its output as it works, maintaining a clean project state.
