Analytics dashboard for Claude Code sessions.
Parses JSONL conversation logs from ~/.claude/projects/ and serves a web UI with:
- Model usage breakdown — doughnut chart showing distribution across Opus, Sonnet, Haiku
- Token stats — input, output, cache read, cache create per session
- Cost estimation — estimated API value based on Anthropic pricing (not actual spend)
- Project filtering — sidebar with search, select/deselect all
- Date range filtering — presets (today, 7d, 30d) or custom range
- Sortable sessions table — all metrics per session
CRT aesthetic inspired by Serial Experiments Lain, with dark and light themes.

Everything runs locally — no telemetry, no session data leaves your machine. The frontend loads Google Fonts and Chart.js from CDN (standard browser requests, no app data sent).
The app runs in a Docker container with ~/.claude/projects/ mounted read-only at /data. A FastAPI backend scans the JSONL session files (including subagents/ subdirectories) and serves both the API and the static frontend.
- Backend: Python / FastAPI
- Frontend: Vanilla JS, Chart.js (CDN)
- Container: python:3.12-slim, non-root by default
