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:
import json
import os
import subprocess
from datetime import datetime, timedelta
from collections import defaultdict
def get_git_info(path):
if not os.path.isdir(path) or not os.path.exists(os.path.join(path, '.git')):
return None, 0
try:
result = subprocess.run(['git', '-C', path, 'remote', 'get-url', 'origin'],
capture_output=True, text=True, timeout=5)
remote = result.stdout.strip() if result.returncode == 0 else None
if remote:
remote = remote.replace('[email protected]:', 'github.com/').replace('.git', '').replace('https://', '')
week_ago = (datetime.now() - timedelta(days=7)).strftime('%Y-%m-%d')
result = subprocess.run(['git', '-C', path, 'rev-list', '--count', f'--since={week_ago}', 'HEAD'],
capture_output=True, text=True, timeout=5)
commits = int(result.stdout.strip()) if result.returncode == 0 else 0
return remote, commits
except:
return None, 0
# Parse history
history = []
with open(os.path.expanduser('~/.claude/history.jsonl'), 'r') as f:
for line in f:
try:
history.append(json.loads(line))
except:
pass
# Filter last N days (default 7)
days = 7
now = datetime.now()
cutoff = (now - timedelta(days=days)).timestamp() * 1000
projects = defaultdict(lambda: {'prompts': [], 'sessions': set()})
for entry in history:
ts = entry.get('timestamp', 0)
if ts >= cutoff:
project = entry.get('project', 'unknown')
projects[project]['prompts'].append(entry)
projects[project]['sessions'].add(datetime.fromtimestamp(ts/1000).strftime('%Y-%m-%d'))
# Collect data
results = []
total_commits = 0
for project, data in projects.items():
remote, commits = get_git_info(project)
total_commits += commits
results.append({
'name': os.path.basename(project) or project.replace('/Users/ris/', '~/'),
'folder': project.replace('/Users/ris/', '~/'),
'remote': remote,
'prompts': len(data['prompts']),
'sessions': len(data['sessions']),
'commits': commits
})
results.sort(key=lambda x: -x['prompts'])
max_prompts = results[0]['prompts'] if results else 1HTML Template
Use terminal aesthetic with:
- Monospace system fonts:
'SF Mono', 'Monaco', 'Inconsolata', monospace - Dark background:
#0d0d0d - Muted colors:
#b0b0b0(text),#555(dim),#4ec9b0(cyan),#ce9178(orange) - ASCII box-drawing for header
$ command --flagsstyle section headers- ASCII bar chart using
