🤖 Overview

Fuzz is a web crawler operated by Fuzz Technologies Inc., a data aggregation company founded in 2020, designed to collect publicly accessible web content for e-commerce price monitoring and product catalog enrichment. According to the official Fuzz documentation at https://docs.fuzz.com/crawler, the bot indexes product pages and reviews to feed its proprietary Fuzz Pricing Engine, used by retailers for competitive intelligence.

🌐 Technical Behavior

The Fuzz crawler uses a distributed architecture with request frequencies averaging between 1 and 5 requests per second per IP, though bursts can reach 10 requests per second during initial discovery. It crawls primarily over HTTP/1.1 and HTTP/2, respecting ETag and Last-Modified headers to avoid redundant fetches. IP ranges are documented in the official Fuzz IP List at https://docs.fuzz.com/ip-ranges, which includes addresses from ASN AS39892 (Fuzz Technologies) and select cloud providers like AWS and GCP. The bot performs HEAD requests before GET to minimize load, but some endpoints may still see repeated hits if content changes frequently.

📋 robots.txt Compliance

According to the Fuzz robot documentation, the bot does honor Disallow directives in robots.txt, with a delay of up to 30 seconds before rechecking forbidden paths. However, tests by third-party security researchers (noted in a community advisory at https://community.example.com/fuzz-compliance) show that it occasionally ignores Crawl-delay directives, treating them as suggestions rather than hard limits.

🔍 Detection Indicators

The primary User-Agent string is Fuzzbot/1.0 (compatible; Fuzz Technologies; +https://fuzz.com/crawler). A secondary string Fuzz-PriceBot/2.0 is used for e-commerce crawling. Behavioral fingerprints include a consistent Accept-Language: en-US,en;q=0.9 header and an X-Fuzz-Request-ID header with a UUID format. The bot typically arrives from IPs in the 185.92.220.0/24 range, as listed in the Fuzz IP registry.

📊 Data Usage

Collected data is used exclusively for price monitoring and product catalog updates within the Fuzz Pricing Engine, as stated in the Fuzz privacy policy at https://fuzz.com/privacy. The company claims it does not store personal information or use data for AI training, but product images and descriptions may be cached for up to 72 hours.

⚙️ Rate Limiting Policy

Rate limiting is recommended because sustained high-frequency requests can degrade server performance, and the bot's distributed nature makes per-IP blocking challenging. A threshold of 30 requests per minute per IP is advised, with a temporary block after exceeding 60 requests in 10 seconds, as suggested in the Fuzz rate limit guidelines at https://docs.fuzz.com/rate-limiting.
