Into the Scrape-Verse · Bright Data × WeMakeDevs

Bright Data repairs a broken scraper. Something has to notice it broke.

PriceGuard reads the rows a run came back with, not the job status, because a scraper that broke overnight still reports success and still returns a normal row count.

Showing the captures committed in this repository

Every price on this page carries the capture that confirmed it.

Built from the captures committed with this page (fixtures/live), so what you read is exactly what shipped.

A refresh re-runs the projection over a store of captures. It never runs the scraper, so it spends no Bright Data credits.
