Bots are built to dominate high-demand drops and on-sales. CrowdHandler layers CAPTCHAs, fingerprinting, threat intelligence and anomaly detection to push automated traffic out of the line — so inventory reaches the genuine customers you want.
Require a CAPTCHA to join the line and you make it dramatically harder for automated traffic to flood your waiting room. We support Google reCAPTCHA, hCAPTCHA and include ALTCHA, so you can choose the right friction for your audience.
Browser fingerprinting ties each visitor to their CrowdHandler token, shutting down token-sharing and collusion between queue users. Combined with destroy-on-checkout, it ensures a single position can't be exploited for multiple orders.
We analyse every queue session across more than 20 metrics to flag anomalous behaviour, and reference live IP intelligence databases to block known threats like data centres and proxies before they reach your site.
Protecting your products from bots requires a layered defense working in concert to deny the fraudsters their margins.
The queue's biggest anti-bot lever isn't a security feature — it's the countdown room. When positions are allocated randomly at go-time, the bot strategy of arriving first becomes worthless. Operators don't disappear, but their economics get a lot worse.
Require visitors to complete a CAPTCHA before joining the queue, not at checkout. Choose ALTCHA (included, open source, no third-party account), Google reCAPTCHA, or hCaptcha. CAPTCHA at the door slows automation when it's cheapest to slow it - before it's holding thousands of positions you can't reclaim
All sessions are profiled across more than 20 metrics including geography, velocity, url focus, and ip reputation to flag anomalous sessions. Anomalous sessions can be flagged, challenged or blocked.
Combine IP, geolocation, user agent and language data into a per-session fingerprint. Sessions can't be shared, sold or split across multiple devices — the queue position belongs to the device that earned it.
Most bots don't act like humans, they target API calls directly to grab stock fast. CrowdHandler can protect your API as well as your human-facing pages. Furthermore, we can detect API specific attacks on platforms like Shopify.
Every session is screened on arrival against a database of known malicious IPs — including data centres, TOR exits and ranges associated with prior bot activity. The simplest, fastest-acting layer. Most automation runs from somewhere these lists already know about
