Plausible

Build me a privacy-first web analytics tool like Plausible (personal scale). Requirements: - A <2KB tracking snippet (vanilla JS, no cookies): sends pageview beacons with path, referrer, screen class, and a daily-rotating visitor hash computed server-side from IP + user-agent + a salt (never store raw IPs). - An ingest endpoint that filters obvious bots by user-agent and writes to SQLite. One row per event; index on (site, date). - A /dashboard (basic-auth from .env): unique visitors, pageviews, top pages, top referrers, and countries for today/7d/30d, with a visitors-per-day bar chart as inline SVG. Fast and clean, dark mode. - Sessionization: a visit ends after 30 idle minutes; compute bounce rate. - Multi-site support via a site id in the snippet. - Node or Python, one process. Honest note in the README: at serious traffic, self-host the real Plausible instead · this is for personal sites.
