Track any product.
Capture the All-Time Lowest Price.
Automated multi-store price monitoring with ordinary least squares trajectory forecasting and Pareto optimization. Checks prices every 4 hours and sends immediate alerts to your Telegram, WhatsApp, or Webhooks.
Decision Science & Automation
Mathematical price modeling • 4-hour background cycle
Discovery & Search
Explore 10–15 candidate products across any storefront. Multi-objective Pareto frontier filtering isolates non-dominated price-to-rating options.
Automated 4-Hour Cron
GitHub Actions schedules continuous extractions every 4 hours with exponential jitter backoff and SSRF loopback defense.
Predictive Decision Alerts
Ordinary Least Squares slope analysis and optimal stopping theory (Secretary problem) decide optimal purchase timing with multi-channel alerts.
Defensive Engineering Standards
SSRF Loopback Defense
Strict domain whitelists and private octal/hex IP blocking protect against internal network probes.
Sliding Rate Limiter
Search requests are strictly rate-limited to 5 requests per minute with automated Retry-After headers.
Row-Level Security (RLS)
PostgreSQL RLS locks down personal credentials and isolates user watchlist entries.
Pareto Frontier Optimizer
Multi-objective algorithms calculate non-dominated deals balancing price, discount, and ratings.
Optimal Stopping Theory
1/e statistical cutoff rules compute buy vs. wait probabilities from log-normal price volatility.
5-Channel Alert Dispatcher
Real-time dispatches across Telegram, WhatsApp, Discord, ntfy.sh, and Email via Google Apps Script.
Engineered for Pure Price Transparency
We build institutional-grade price intelligence without commercial bias, ads, or sponsored placements. Our mission is to restore pricing sanity across India's leading e-commerce platforms through data structures and automated monitoring.
