Redlight Greenlight is a native macOS menu bar application designed specifically for Claude Code users. Its main purpose is to display Claude Code permission requests in a floating overlay that appears when Claude needs permission to execute code, allowing users to respond without interrupting their workflow.

The app provides a floating overlay interface that appears automatically when Claude Code requests permission. Users can accept or reject Claude Code permissions directly from this overlay without switching applications. The application runs as a menu bar app on macOS systems.

Redlight Greenlight works by monitoring Claude Code permission requests and displaying them in a floating overlay window. This approach allows users to stay focused on their current application while still being able to respond to Claude's permission prompts instantly.

The primary benefit is maintaining workflow continuity by eliminating the need to switch between applications when Claude requests code execution permissions. This saves time and reduces context switching for developers and users working with Claude Code.

The target users are macOS users who work with Claude Code and want a more efficient way to handle permission requests. The app requires macOS 13+ and supports both Intel and Apple Silicon processors.
