See what competitors stock — and when it sells out
We track competitor and marketplace assortments across your categories, monitor stock and availability over time, and surface the gaps in your own range — so you spot opportunities and stockouts before they cost you sales.
The problem
Assortments shift constantly: rivals add products, quietly delist others, and run out of stock at the worst possible moment. Spotting it by hand across competitors and marketplaces is impossible, so ranging and replenishment decisions get made on a partial, out-of-date picture of the shelf.

Decision-ready data
Not a tool to operate or a raw dump to clean up — structured, ready-to-use data, delivered the way you already work.
- Catalog and assortment coverage by competitor

Use cases
What teams do with it
The same clean, reliable data powers very different decisions.
Range & assortment planning
Compare your range against competitors category by category, and find the products you're missing before a buyer does.
Stockout & availability alerts
Know the moment a competitor sells out — a window to win demand — or when a key line goes out of stock across the market.
New-product detection
Catch the products competitors add as they launch them, so you're never the last to react to a new entrant.
Delisting & long-tail decay
See what rivals quietly drop, a signal of weak demand or margin you can use to prune or double down on your own range.
Share-of-shelf tracking
Measure how much of a category each competitor covers over time, and where your presence is thinning.

FAQ
Common questions
- How do you tell when something is out of stock?
- We capture each product's availability exactly as a shopper sees it on every check, and track it over time — so you get both the current state and the full history of when items went out of and back into stock.
- Can you track assortments across multiple marketplaces?
- Yes. We cover competitor sites and the marketplaces that matter to you, including sources that block most collectors, and normalize everything into one consistent view of the shelf.
- How do you match competitor products to my range?
- We match on whatever identifies a product — your product IDs where you have them, or GTIN/UPC, brand, title, and attributes where there's no clean ID — then quality-score each match so gap analysis is reliable.
- How often is availability checked?
- On a cadence we scope to your category — from continuous intraday monitoring for fast-moving lines to daily or weekly where that's enough. You choose it; we maintain it.
- We've tried monitoring this ourselves and it keeps breaking — can you keep it running?
- That's exactly what we take on. Sources change, access gets cut off, and coverage slips — keeping assortment and availability tracking reliable on the hardest sites is a relentless, full-time job. We absorb all of it and simply deliver the data, so it never lands back on your team.
- How is it delivered?
- However you already work: a REST API, scheduled feeds, direct into your data warehouse, or a ready-made dashboard with change alerts.
