Get an in-stock alert the moment "Sold out" turns into "Add to cart" — on any shop, whether or not it has a "notify me" button. Paste the product URL, point at the stock label, and stop refreshing the page.
Start monitoring free →Limited drops, popular sizes and small-batch products come back in stock for minutes or hours. The store's own back-in-stock email is slow, goes to everyone on the list at once, or does not exist.
The restock that lands at 3am is gone by the time you check at 9. Nobody can watch a product page all day.
"Notify me" emails go out in batches, often after the stock is already gone — and plenty of stores never send one.
The colour or size you need has its own stock status. A site-wide alert does not tell you your variant is back.
Select your size or colour on the store first if it changes the URL, then copy that exact product URL. Each check loads it in a real browser, so JavaScript storefronts work too.
Use the visual picker to select the "Sold out" label, the "Add to cart" button or the availability line. Only that element is compared, so banners and recommendations do not trigger alerts.
Add a prompt such as "notify me when this is back in stock". The AI filter ignores everything else, and the alert arrives with a one-line summary and a highlighted diff of what changed.
One of our paying customers watches a single product page in an online shop for exactly this: the moment it is available again. Typical restock monitors:
Your size of a sold-out shoe, jacket or limited drop.
Graphics cards, consoles and gadgets that sell out on launch.
Limited runs, figures and trading cards that restock without warning.
Wine, coffee, cosmetics and other short runs from independent shops.
A specific model on a dealer stock locator — see car stock alerts.
New flats and houses on agent sites — see property listing alerts.
PageRadar works on most online shops, including Shopify and other JavaScript storefronts. Some large retailers run enterprise bot protection that blocks automated checks, ours included. When a store blocks a check, the monitor is marked Blocked on your dashboard instead of going quiet — so you never wait for an alert that cannot come. Try the product page on the free plan before you rely on it.
For restocks, check frequency is what matters. Your first monitor checks every 15 minutes for 24 hours free; after that the free plan checks daily. Basic ($7/mo) checks hourly and adds Telegram and Slack alerts, Pro every 15 minutes, Business every 5 minutes.
