Track approved product pages, keep an auditable price history, and generate price-drop, target-price, and stock-change alerts with a transparent Python starter kit.

Built for consultants, small sellers, researchers, and solo operators who want an editable local workflow instead of another recurring subscription.

WHAT IS INCLUDED • Dependency-free Python monitoring engine • Editable JSON configuration • Product JSON-LD and common product meta-tag parsing • Append-only price history and change log • CSV, JSON, and HTML alert outputs • Deterministic synthetic demo covering 12 fictional targets • Three unit tests, sample outputs, quick-start guide, privacy notes, and buyer license

REQUIREMENTS • Python 3.10 or later • Verified on Windows 11 with Python 3.12.8 • Internet access only for live URLs or optional SMTP delivery

IMPORTANT LIMITATIONS This is an unsigned source-code bundle, not a signed installer or universal no-code scraper. JavaScript-rendered pages, logins, CAPTCHA, unusual layouts, and sites without structured product data may require custom adaptation. The package does not bypass access controls. Buyers are responsible for authorization and compliance with website terms and applicable law.

Custom website adaptation, hosting, scheduling, and email-provider setup are not included in the download.

PRIVACY The tool reads only configured URLs and writes results locally. It contains no telemetry and does not upload results. SMTP is disabled by default.
