What it solves

Coralline is a highly customizable statusline for Claude Code, providing real-time visibility into the session's technical state. It replaces the default status line with a dense, information-rich bar that tracks everything from git status and environment variables to Claude's internal token usage and rate limits.

How it works

It functions as a command-based status line integrated into Claude Code's settings.json. It can be implemented via a Bash script (statusline.sh) or a native PowerShell port (statusline.ps1) for Windows users. The tool reads session data and renders it using a configurable set of "segments" (e.g., directory, model, cost, and context gauges) using Nerd Fonts for iconography.

Who it’s for

Developers using Claude Code who want a professional, terminal-based dashboard to monitor their AI session costs, token burn rates, and environment context without leaving the prompt.

Highlights

• Comprehensive Session Tracking: Monitors active Claude models, reasoning effort levels, session cost in USD, and wall-clock duration.
• Resource Gauges: Visual indicators for context window usage and rate limits (5h/7d) that change color based on fill percentage.
• Subagent Panel Theming: Ability to theme the subagent rows in Claude Code, adding per-task model info, context gauges, and elapsed time.
• Cross-Platform Support: Native installers for macOS, Linux, and Windows (PowerShell 5.1+).
• Extensive Customization: Supports multiple themes and configurable layout/style options (pill, lean, or classic styles).
