Restock Alerts: Never Miss Your Size Again
Learn how restock alerts work and why they've become essential for European fashion enthusiasts who refuse to settle for the wrong size.
The Problem: The "Out of Stock" Frustration
You know the feeling. You spot the perfect piece on Zara, COS, or Sézane. You click. And there it is: out of stock in your size. You refresh the page 10 times a day for a week. Sometimes it works. Often you miss the restock — it was gone in 15 minutes.
You're not alone. On Reddit, r/Aritzia and r/femalefashionadvice communities are full of threads about restock strategies. Users share their "techniques": checking at 4am, using change detectors, stalking abandoned cart returns.
The finding is clear: retailers' native notification systems are broken. "Back in stock" emails arrive hours late — when they arrive at all.
Why Native Alerts Don't Work
Online stores have little incentive to optimize their alerts:
1. Deliberate latency: notifications are often batched (hourly or less) 2. No size granularity: many sites notify "product back in stock" without specifying the size 3. No prioritization: no difference between a single return and a full restock 4. Emails landing in spam: native systems use unreliable no-reply senders
The Solution: Continuous Size-Level Monitoring
This is exactly what restocking does — and why we built it.
Our worker continuously scans product pages from 120+ major European fashion brands, every 5 to 30 minutes depending on your plan. As soon as a specific size comes back in stock, you get an immediate alert via email or SMS.
How It Works Technically
Our system uses a 4-layer detection approach:
1. dataLayer Analysis: extracting structured JavaScript data 2. "Add to Cart" Button Detection: checking button state 3. Variant Attributes: parsing size and color selectors 4. Semantic Analysis: text classification to confirm status
Double Confirmation: we require two consecutive IN_STOCK detections before sending an alert, to eliminate false positives.
Brands We Monitor
Our coverage is 100% European: Zara, COS, Aritzia, Sézane, Mango, Uniqlo, Massimo Dutti, & Other Stories, Arket, Pull&Bear, Bershka, Stradivarius, H&M, and 100+ more.
Why It's Free (Almost)
We have a Free plan with 3 active alerts, and a Pro plan at €5.99/month for power users. We want the tool to be accessible to everyone, not just tech early adopters.
The first 100 signups get 3 months of Pro for free.
