Use case - Catalog pulse report
See their launches, often before they go live
Brands add new products and categories to their catalog before the homepage, ads or emails show them, and every quietly retired SKU is a signal too. RivalSweeper tracks the launches and pullbacks across your competitive set and surfaces them as a simple pulse - so you move in weeks, not quarters.

Catalog pulse - real sample, anonymized
Captured Oct 14, 2026 - An activewear competitive set of 18 brands (US and Europe), Sep 15 - Oct 14, 2026
Notable new arrivals
- Bars: Brand A-E are US activewear and basics brands, Brand F is a Swedish activewear brand. 3 more brands added 17 products between them.
- Not counted: one brand's first full catalog read (a baseline, not new arrivals) and one store whose product count read as zero (a read failure, not a cull).
The problem this solves
Sound familiar? Here is how RivalSweeper changes each scenario.
A competitor launched a new line last month. You heard about it from a customer asking why you do not carry it. Embarrassing - and late.
Live catalog tracking flags every new product within 48 hours of it appearing in a competitor's catalog, often before they promote it, so you learn about a launch from us, not from a customer.
A rival is quietly building out a new category - a few SKUs a week - and by the time you notice they have a beachhead you cannot easily take back.
The pulse shows launch velocity per brand, so a slow, deliberate category build is visible in week one, giving you months of lead time to respond.
You cannot tell what competitors are backing away from - the discontinued items that reveal what is not working for them.
Retired SKUs are tracked alongside new ones, so you see both what rivals are betting on and what they are cutting - and avoid their dead ends.

A simple new-versus-gone view per brand, plus the categories where launch velocity is picking up.
Respond first
Fast-track sourcing against a launch you caught in week one, and steer clear of the categories rivals are retreating from.
The features behind it
Why RivalSweeper for this
- Launches surfaced within 48 hours, often before the brand announces them
- New arrivals and discontinued SKUs together - what they back and what they cut
- Launch velocity per brand reveals a quiet category build early
- Whole-set view, deduped across locales and variants, not one tab at a time
Frequently asked questions
How do eCommerce teams monitor competitor assortment changes?
RivalSweeper tracks every competitor's full catalog and detects when products are added, removed, or shifted between categories. Instead of checking sites manually, teams get a pulse of new arrivals and discontinued SKUs across the whole competitive set, refreshed every day.
How fast will I know when a competitor launches a new product?
Within 48 hours of the product appearing in their catalog. Brands often add products to their catalog before they promote them, so you frequently see a launch before it is announced.
Does it also show what competitors discontinue?
Yes. Retired SKUs are tracked alongside new ones, which tells you what a competitor is quietly backing away from as well as what they are betting on.
