50+ Data Points

Canvas, audio context, WebGL renderer, font enumeration, battery status, privacy flags, timezone, language, and dozens more — all from one lightweight collector.

Zero-Dependency SDK

Under 5KB gzipped. One script tag, no build step, no config. Works on every modern browser with zero external dependencies.

📈

Real-Time Dashboard

Dark-themed live dashboard with visitor timeline, device breakdown, geo map, and per-session drill-down. Built with Chart.js.

🔒

Privacy-First Design

Server-side geolocation. No third-party tracking. No cookies required. Your data stays in your SQLite database — nobody else sees it.

🧠

AI-Powered Insights

Kimi 2.5 analyzes visitor patterns, detects anomalies, and surfaces actionable intelligence. Ask questions about your traffic in natural language.

💰

Free Forever

No billing, no usage limits, no premium tier. Every feature is available to every user at zero cost. Self-hosted, self-owned.

Seven algorithms. One unified signal.
Each algorithm detects different patterns in visitor behavior. The ensemble combines them into a single confidence score.
📊

BOCPD

Bayesian Online Changepoint Detection. Identifies abrupt shifts in traffic patterns and visitor composition in real time.

📈

GPR

Gaussian Process Regression. Models smooth trends with uncertainty bounds. Reveals the underlying trajectory beneath noisy data.

🔀

HMM

Hidden Markov Models. Discovers latent behavioral states — are visitors browsing, comparing, or ready to convert?

Survival Analysis

Time-to-event modeling. Predicts when visitors will return, churn, or convert based on historical cohort data.

🚨

CUSUM & PELT

Cumulative sum and pruned exact linear time. Industrial-grade changepoint detection for traffic volume anomalies.

📐

Matrix Profile

Finds recurring motifs and discords in time series. Detects bot patterns, periodic traffic spikes, and unusual sequences.

🎯

Ensemble

Weighted combination of all six algorithms. Produces a single confidence score and directional signal with explainable reasoning.

Built for speed and reliability
TypeScript + Fastify backend, SQLite WAL storage, Chart.js visualizations. Everything self-contained.
🚀

Fastify API

TypeScript backend on Fastify with schema validation. REST endpoints for fingerprint collection, visitor queries, and AI analysis.

🗃

SQLite WAL

Write-ahead logging for concurrent reads during writes. Zero-config, single-file database. No external database server required.

📊

Chart.js Dashboard

Dark-themed analytics dashboard with real-time charts, visitor timelines, device breakdowns, and interactive drill-downs.
