Use case

Track competitor prices automatically

To track competitor prices, point Page Byte at a product or catalog page and describe the fields — 'every product: name, price, availability'. Schedule it hourly, and Page Byte alerts you with an AI summary whenever a price moves. Use the multi-URL batch to watch the same SKU across many stores at once.

Price intelligence is the most common reason teams scrape the web. The hard part isn't the first scrape — it's keeping it running as stores redesign their pages and change their markup.

Page Byte's self-healing extractor survives those redesigns, and its diff engine surfaces only what changed: 'three price drops averaging 12%, one item out of stock, two new SKUs'. Point it at up to 50 URLs to compare the same product across competitors in one table.

Frequently asked

Can I monitor the same product across several stores?
Yes. Page Byte's multi-URL batch applies one extractor across a list of URLs and tags each row with its source, so you get a single price-comparison table.
How often can prices refresh?
As often as every 5 minutes on paid plans, down to daily or weekly. You're alerted only when a price actually changes.
