Keep scrapers off your content
Tie every request to a stable device, see through proxy rotation, and enforce at the edge — so scrapers can't drain your catalog, pricing or API.
Why IP rate limits fail
Scrapers rotate through thousands of residential proxies, so an IP-based limit resets on every request. The fix is to rate-limit by a stable device fingerprint — one budget per device, no matter how many IPs it burns through.
Server-side detection
Headless browsers, automation frameworks and HTTP libraries caught from raw tells the client cannot spoof.
Rate-limit by device
Throttle by a stable device fingerprint, not IP — so proxy rotation does not reset the budget.
Proxy & datacenter
Residential-proxy, datacenter and Tor detection flags the networks scrapers hide behind.
Edge enforcement
Cloudflare Worker and nginx connectors block or challenge sub-10ms, before scrapers reach your origin.
Detect the whole toolkit
From headless Chrome to raw HTTP clients, Prynt reads the JA4 TLS fingerprint and automation tells that give a scraper away — including AI crawlers harvesting content for training.
