Price intelligence for marketplace sellers. Pricing health, competitor benchmarks, and an always-on watchlist — all from your browser.
Paste a list of ASINs or upload an Excel/CSV. Ruby checks every listing in parallel — buy box price, seller, stock status, deal flag — and labels each row.
FOD · OOS · Low StockStar the 5–60 ASINs that pay your bonus. Ruby checks them continuously in the background — calm, balanced, or aggressive cadence — so you know within minutes when something changes.
New in v7.1A persistent panel at the edge of Chrome shows live status, rotating ASIN cards, and action-required event cards when something needs you. Click any event to jump to its full timeline.
New in v7.1Every starred ASIN's last 24 hours or 7 days as a colored band — winning, lost to 1P, FOD, OOS, deals, price changes — at a glance. Click any cell for the snapshot details.
New in v7.1Upload your competitor monitoring file. Ruby reads live prices from each competitor site side-by-side with your marketplace price and labels each row Competitive or Not Competitive.
Live comparisonAny site, anywhere. Open a product page, click the price element, and Ruby learns it. No code, no configuration files, no developer needed. Six major sites ship configured out of the box.
Works on any siteOne click exports the current view to a formatted Excel file. Or set a fixed output file and Ruby will keep it updated as you run new checks.
Auto-save modeEvery check runs inside your browser. No price data, no product data, no browsing history is ever collected or transmitted. The only network call is a one-time license activation.
Privacy firstStar up to 60 ASINs and Ruby will check them continuously in the background. You see the live status in a persistent side panel at the edge of Chrome — and the moment something changes, an action card appears so you can act in seconds.
Calm (90–180s), Balanced (30–120s), or Aggressive (10–30s). Quiet hours pause notifications overnight.
FOD, lost Buy Box, 1P takeover, OOS, low stock, price drop — each event surfaces with Open in Seller Central, Snooze, and Mark Resolved.
Critical events (FOD, OOS, 1P takeover, price reduction) ping your OS. Click the notification to jump to the affected ASIN's timeline.
Opt-in toggle keeps Chrome alive while your screen is locked — so the heartbeat keeps ticking overnight. Best on plugged-in machines.
Listing is live with a buy box price. Ruby captures the price and seller name.
A competitor site is selling the same item for less. The marketplace removed the Buy Box until you match the cheaper price elsewhere.
No stock available on the listing. Ruby flags it so you can replenish before you lose ranking.
Inventory is running low. Replenish before it goes OOS and you drop in search ranking.
The listing is running a deal. Ruby captures the deal price and flags the discount window.
Type ASINs directly or upload an Excel/CSV file. Ruby reads your list and queues every item.
Opens background tabs at your chosen speed (pinned as a favicon, never full-width), reads each listing, and updates the table in real time.
Star the ASINs you care about. Ruby starts watching them in the background and shows live status in the side panel.
Download a formatted Excel file with the current view. Set a fixed output file and Ruby will keep it updated automatically as you run new checks.
