Price history — 30 days
Illustrative tracker. Real values are observed at each scheduled check and shown with their timestamp.
Daily Price History
See how a product's price has moved, not just what it costs today.
Buy Box Watch
Know who holds the Buy Box on the listings you care about.
BSR Trends
Best Sellers Rank history to spot momentum or decline early.
Rating & Review Count
Track how star rating and review totals change over time.
Six signals tracked for every product
One snapshot tells you little. A dated history of the public details that move sales tells you what is actually happening.
Price Movements
Price history with the lows, highs and recent changes — so you can tell a promotion from a permanent cut.
Buy Box Ownership
Which seller held the Buy Box when it was checked, and when that changed on your own listings.
BSR History
Rank trends in the product's category. Sales figures derived from rank are always labelled as estimates.
Ratings & Reviews
Changes in average rating and total review count, so a slide doesn't go unnoticed.
Offer Count
How many sellers are offering the product — a signal of new competition arriving.
Listing Changes
Notable changes to the title and key listing details between checks.

See the history
Charts show how price, rank, rating and offers moved — with the time of the last check always visible.

See the moves competitors make, without checking by hand
Price cuts, lost Buy Boxes, new sellers and listing edits show up in one timeline instead of dozens of browser tabs.
Spot price wars early
Price history shows whether a drop is a short promotion or a lasting change.
Honest boundaries
We track public marketplace details only — never a competitor's private data or exact sales.
You stay in control
We show what changed. Pricing and listing decisions stay with you — nothing is changed automatically.
Recent changes — tracked competitors

Where tracking pays for itself
Competitor Watch
Keep an eye on the listings you compete with and notice when they cut price or change their listing.
Buy Box Defense
See when the Buy Box on your own listing moves to another seller so you can investigate.
Product Research
Watch a candidate product for weeks before committing — price stability and rank trends tell a story.
Pricing Decisions
Use real price history, not a single snapshot, when setting or adjusting your own prices.
