Claude Code History Viewer

A simple web application to view conversation history from Claude Code.

Features

• 📁 Browse all Claude Code projects
• 💬 View conversation history in projects
• 🎨 Modern web interface
• 🔍 Support for viewing complete message content, including thinking processes and tool calls
• 🚀 Automatic port detection, automatically uses other available ports if the default port is occupied

Requirements

• Python 3.6 or higher
• Claude Code installed with conversation history generated

Installation

Install via pip (Recommended)

The easiest way to install is using pip:

pip install claude-code-history

Or install from source:

pip install git+https://github.com/chenwei-zhang/claude-code-history.git

Install from source

1. Clone or download this project:

   git clone https://github.com/chenwei-zhang/claude-code-history.git
   cd claude-code-history
   

2. Install the package:

   pip install .
   

3. Ensure Python 3.6+ is installed:

   python3 --version
   

The project uses Python standard library, no additional dependencies required.

Usage

After installation, you can run the application using the claude-code-history command:

1. Run the application:

   Use default port 8000:

   claude-code-history
   

   Or specify a custom port:

   claude-code-history --port 8080
   

   Or use the short form:

   claude-code-history -p 8080
   

   If you installed from source without pip, you can still run:

   python3 app.py
   

2. Open your browser and visit:

   http://localhost:8000
   

   (If you specified a different port, use that port number instead)

   If the specified port is occupied, the program will automatically use other available ports (+1, +2...), and display the actual port used in the terminal.

3. Browse your Claude Code project history in the browser

4. Stop the server:

   • Press Ctrl+C in the terminal

How It Works

The application reads conversation history from Claude Code's storage location:

• macOS/Linux: ~/.claude/projects/
• Windows: %USERPROFILE%\.claude\projects\

Each project folder contains multiple .jsonl files, each representing a conversation session. The application parses these files and displays them in the web interface.

FAQ

Q: What if the port is occupied?

A: The program automatically detects and uses other available ports. If the default port 8000 is occupied, it will automatically try ports 8001, 8002, etc., and display the actual port used in the terminal.

Q: What if no projects are found?

A: Make sure you have used Claude Code and generated conversation history. Project data is stored in the ~/.claude/projects/ directory.

Q: Can I change the port?

A: Yes! Use the --port or -p argument to specify a port, for example: python3 app.py --port 8080. If not specified, it defaults to port 8000.

Q: What operating systems are supported?

A: Supports all operating systems running Python 3.6+, including macOS, Linux, and Windows.
