Instant desktop alerts when new OfferUp listings match your saved searches. One dashboard for every search you're running. OfferUp's own alerts only reach you by email or an in-app push — easy to miss, slow to check, and there's no single place to see what's new across more than one search at once. By the time you open the app, the good stuff is already sold. OfferAlert watches your OfferUp searches for you and fires a real desktop notification the moment something new posts. Paste any OfferUp search URL, set an optional max price, and OfferAlert rechecks it automatically in the background — even when the tab isn't open. Features: - Paste-a-URL setup — no configuring filters twice, just reuse the search you already ran on offerup.com - Real desktop notifications, not another email to miss - Optional max price per saved search - A single Matches tab collects every new hit across all your saved searches - Runs automatically on a background timer, no need to keep OfferUp open - One-click test notification so you know it's working - Free: 2 saved searches, checked every 5 minutes. Pro: unlimited saved searches, checked every 2 minutes Add OfferAlert and stop losing local deals to whoever refreshes faster.
