A watch list operators could manage.
A multi-brand sleep portfolio needed a tool for recording competitor prices and reviewing changes over time. Operators needed control of the targets without editing the application code.
Targets, collection and history.
Each target stored a label, source URL and selector for extracting the displayed price. The app supported scheduled collection and manual refresh, with a record of previous values.
An embedded app and metafield updates.
The Shopify app included authentication, an interface for adding and editing targets, and charts and tables for reviewing historical snapshots. Collected prices could be written to Shopify metafields.
Maintenance and evidence limits.
The implementation record includes runtime and Shopify API updates over several years. Selector-based extraction can break when a source website changes.
The record establishes what was built and maintained. Current production use, price accuracy and commercial impact have not been verified here.
