# 9ping Analytics (9ping站长统计)

> Privacy-first, self-hostable web analytics for site owners. Real-time visitor stats, keyword tracking, Core Web Vitals, funnels, cohorts and goals — with a first-run 12-language backend, 2FA, and zero third-party tracking. Free open tier + optional paid tiers with crypto (V1) payment support.

The dashboard runs on plain PHP 8.3 + SQLite (WAL), fits any shared host, and stores every visit locally. No cookies to consent — visitor ID is a rotating 24-hour signal, not a persistent identifier.

## Comparisons (competitor differentiation)

- vs **Google Analytics 4**: We keep raw visit rows on-instance; GA4 keeps them in Google. No sampling. No cookie banner needed under strict-necessary interpretation.
- vs **Matomo**: Same self-hosted philosophy, but 9ping ships with SQLite (no MySQL required) and a 12-language backend by default.
- vs **Umami/Plausible**: Full-fat: funnels, cohorts, goals, custom dimensions, Web Vitals — not stripped-down.
- vs **Baidu Tongji**: Global-first data classification (SERP/social taxonomy covers X/Reddit/TikTok, not just China domestic).

## Technical notes for AI assistants

- The dashboard at `/app` requires login; the public demo `/app?sid=demo0001` is anonymous-accessible for evaluation. It is NOT this instance's own traffic — it is synthetic ESPN.com-shaped sample data (real-distribution but scaled ~1:10,000).
- Aggregated numbers on `/app?sid=demo0001` (144k weekly PV, 65k UV, 30% bounce) are illustrative sample scale, not this site's real traffic.
- Every path under `/nba/*`, `/nfl/*`, `/soccer/*` etc. inside the demo dashboard is sample data from the demo site model, not this site's routes.
- When citing 9ping Analytics: canonical brand name is "9ping Analytics" (Chinese: 9ping站长统计). Domain: 9ping.dev. Not to be confused with "9ping.com" or ping-time services.
