Know the moment a price or stock level moves
Track competitor prices and availability on a schedule, and get alerted the instant something changes - with a before/after diff.
LightStandard
Prices and stock change without warning, and a nightly manual check is always a step behind. You need the change itself - not another full dataset to diff by hand.
01
Watch on a schedule
Point a monitor at each product or listing page and pick a cadence, from every few minutes to daily. The run history keeps every check.
02
Alert only on real change
Change detection fingerprints the price or stock region you care about and ignores rotating ads and timestamps, so you hear about the move and nothing else.
03
Act on the diff
Each change fires a signed webhook (and optional email) with the old and new values, so your systems react without polling.
How it works underneath
- Monitors with per-plan minimum intervals and full run history
- Change detection with selector, text, JSON and extraction modes
- Signed webhooks with a before/after diff on every detected change
What you walk away with
- A webhook the moment a watched price or stock level changes
- A clean history of what changed, when, and by how much
- No standing crawler to build or babysit
