Marketplace Alert Questions, Answered

Classifindr is a self-serve marketplace alert app for web, iOS, and Android. It checks Auto Trader, CarGurus, Cazoo, Facebook Marketplace, Gumtree, Craigslist, Trade Me, Kijiji, OfferUp, Poshmark, Pinkbike, Vinted, eBay, Depop, Mercari, and Chrono24 where available, then sends useful matches to your chosen alert channels.

Browser extensions and manual refreshing usually depend on you being at the right computer with the right tab open. Classifindr runs searches from your saved configuration, monitors multiple searches across multiple marketplaces in parallel, and sends alerts to mobile push, Telegram, Discord, email, or Web Push when a check finds a match.

You can create searches for cars, electronics, furniture, tools, collectibles, sporting goods, property, and more across supported marketplaces, including fixed-price eBay listings in selected countries.

Yes. Every new subscription includes a 7-day free trial with 10 units. That is enough to try one search checked every 1 minute and one search checked every 10 minutes on one marketplace each. Your payment method is collected at checkout, but you are not charged until the trial ends, and you can cancel anytime during the trial to avoid being charged.

No. You can use Classifindr entirely from a browser with no extension required, and the same account also works in the native iOS and Android apps. Alerts can be delivered through mobile push, Telegram, Discord, email, or Web Push so you receive them on the device and channel that fits the search.

The Classifindr app is free on the App Store and Google Play. Search for "Classifindr" in either store, or visit our mobile page for direct links. Sign in with the same account you use on the web. The app supports passkeys, Sign in with Apple, Google, and email magic-link.

The apps use Apple Push Notification service on iOS and Firebase Cloud Messaging on Android, the standard systems for native app notifications. After a check finds a match, mobile push can reach your phone even when the app is in the background or closed, subject to Apple, Google, carrier, and device notification settings.

Classifindr is available globally, while individual marketplaces cover different regions. If eBay is unavailable for your search location, that source is disabled for the search and uses 0 units.

Classifindr checks as often as every minute on the fastest tier. After a check finds a new matching listing, it sends the alert to your chosen channel shortly after. End-to-end timing depends on when the listing appears relative to your next check, marketplace availability, and the notification channel you use.

You choose the check speed per search: checked every 1 minute, every 10 minutes, or every 60 minutes. The 1 minute option is for time-sensitive hunts where being first matters. The 10 and 60 minute options stretch your units across more searches when speed is less critical. You can mix and match check speeds across your searches so high-priority hunts run faster than the rest.

Classifindr sends alerts through mobile push, Telegram, Discord, email, Web Push, and webhooks. You can connect multiple channels per search and route different searches to different channels, including your own tools.

Classifindr applies three layers of filtering to every search so less noise reaches your phone. Your search parameters (keywords, picked location, radius, price, and sometimes category or condition) narrow the field at the platform level. A title-rule engine then runs Require, Exclude, and Override rules on each fetched listing. AI relevance can help identify mismatches keywords cannot see, like "iPhone case" when you want a phone. Filtered listing review then lets you inspect filtered-out listings before making the rules stricter.

Every search shows current health information in your dashboard, so you can see when a search stops matching anything. Filtered listing review also helps you catch over-tight rules because you can inspect listings that were filtered out and see why. If useful listings are being blocked, loosen an exclude rule, broaden a keyword, increase your price ceiling, or adjust AI relevance. Because Classifindr lets you adjust filters without rebuilding the search, tuning is a continuous workflow, not a one-time setup.

Classifindr gives you several layers to keep alerts signal-rich. You set keyword rules per search to require or exclude specific terms (for example, require "leather" and exclude "replica"). AI filtering scores each listing's title and thumbnail against your search description, helping prioritize listings that match what you are looking for. Use filtered listing review to see which listings were filtered out and why, then adjust one rule at a time.

Yes. Classifindr has filtered listing review in the alert feed. You can switch between matched, filtered, and all listings, inspect match reasons, and use that context to tune include terms, exclude terms, price, radius, and AI relevance. That feedback loop helps reduce junk without silently hiding listings you would have wanted.

Yes. Custom URL mode lets you paste a supported marketplace search URL you already built, then layer Classifindr title and location keyword rules, AI relevance filtering, filtered listing review, and alerts on top. Use it for single-platform searches when the copied address carries advanced marketplace filters such as vehicle make, model, year, category-specific filters, region boards, or native filter combinations. OfferUp uses standard search fields instead of Custom URL mode.

Yes. Classifindr lets you connect multiple mobile push, Telegram, Discord, email, Web Push, and webhook channels and assign each search to whichever channels you want. A common setup is to send your most important search to mobile push or Telegram, and route lower-priority searches to a Discord server or an email inbox so they do not interrupt you.

Search pricing keeps choosing simple, while units keep the plan flexible. Checkout converts your selected searches into reusable units so you are not locked to the exact searches you picked. You can swap one search checked every 1 minute for several searches checked every 60 minutes, change marketplaces, or pause one search and use that room elsewhere when the new setup still fits.

Classifindr uses unit-based pricing instead of fixed plans. Every active search reserves units based on the check speed you choose and how many marketplaces it checks. A search checked every 60 minutes costs 1 unit, every 10 minutes costs 3 units, every 1 minute costs 7 units, and each unit is $1.60 a month or $0.50 a week. Monthly checkout starts at 3 units ($4.80/month), and weekly checkout starts at 5 units ($2.50/week). Pause or deactivate a search and its units immediately return to your active search capacity, ready to fund a different search. Large packs also earn bonus units at no extra cost. See the pricing page for full plan details.

Review the billing currency, applicable tax treatment, and final total on the pricing page and at checkout before you subscribe.

Yes. Classifindr has no long-term contracts. You can cancel at any time from your account settings, your searches remain active until the end of your current billing period, and your search configuration is preserved if you ever want to resubscribe.

Webhooks send signed HTTPS events to a tool or endpoint you control. V1 includes new-listing matches and price decreases, with the listing, search, and match context your workflow needs.

Create one in the desktop web portal, save the whsec_ secret when it is shown once, verify the endpoint with a signed test event, and assign it to your searches. Mobile can view and assign active channels, but setup and delivery history are desktop-web-only in v1.

Yes. Webhooks are available to all accounts with no webhook-specific surcharge.

No. Verification proves signed reachability and a 2xx response, not ownership. Only configure an endpoint you are allowed to use.

Mobile can display and assign existing active webhook channels. Create, verify, rotate, inspect, and redeliver webhooks from the web portal.

Yes. Classifindr encrypts your data in transit and at rest, isolates your account data from other tenants, and never sells or shares your personal data. Sign-in supports passkeys for phishing-resistant authentication, and your billing details are handled by our payment provider so we never store your card. See the security page for full details.

No. Classifindr never asks for or stores marketplace login credentials, including Cazoo, Mercari, and Pinkbike sign-in details. Your marketplace accounts remain separate from your Classifindr account.
