Claude Code Analytics
Generate HTML report of Claude Code usage from ~/.claude/history.jsonl.
Data Sources
- History:
~/.claude/history.jsonl— prompts with timestamps and project paths - Git: Remote URLs and commit counts per project
Output
Single HTML file with terminal aesthetic:
- ASCII art header
- Summary stats (projects, prompts, commits, days)
- Project table with remote links
- ASCII bar chart
Generation Script
Run this Python script to generate the report:
