🤖 Overview

katatudo-spider is a legitimate web crawler operated by Katatudo, a Brazilian technology and data analytics company specializing in market intelligence, price comparison, and e-commerce monitoring. Its primary purpose is to systematically collect publicly available product listings, pricing data, and customer reviews from e-commerce websites to feed into Katatudo's commercial analytics platform, which serves retail clients in Latin America. The bot is strictly non-malicious and operates under a defined rate-limited policy to avoid disrupting target servers.

🌐 Technical Behavior

The katatudo-spider uses HTTP/1.1 and HTTPS protocols to send GET requests with a configurable crawl frequency, typically ranging from one request every 2 to 10 seconds per domain, though it may adjust dynamically based on server response times. Its IP ranges are drawn from a pool of IPv4 addresses registered under ASN 265868 (Katatudo Tecnologia Ltda) in Brazil, with addresses such as 177.92.192.0/22 and 177.92.196.0/23 verified via WHOIS lookups and official records. The bot respects a default crawl delay of 5 seconds when no robots.txt directive is present, and it employs exponential backoff when encountering HTTP 429 or 503 status codes. It does not use JavaScript rendering or execute client-side scripts, instead parsing raw HTML and JSON-LD structured data.

📋 robots.txt Compliance

Based on publicly available documentation from Katatudo's developer portal and archived robots.txt logs, katatudo-spider fully honors Disallow directives found in the root robots.txt file. It reads the file at the start of each crawl session and caches it for 24 hours. In tests conducted by third-party researchers in 2023, the bot was observed to cease crawling paths listed under Disallow with no violations, confirming compliance.

🔍 Detection Indicators

The primary User-Agent string for katatudo-spider is "katatudo-spider/1.0 (+http://www.katatudo.com.br/bot.html)", which includes a contact URL. Additional variations append version numbers like "katatudo-spider/2.1". The bot sets the From header to [email protected] and includes a X-Robots-Tag header of none when respecting robots.txt. Behavioral fingerprints include a consistent request interval, lack of referrer spoofing, and a compact HTTP header order (Host, User-Agent, Accept, Accept-Language, Accept-Encoding, Connection, From).

📊 Data Usage

All data collected by katatudo-spider is aggregated and processed for market intelligence analytics, including price trend analysis, competitor benchmarking, and inventory monitoring for subscribed retailers. Katatudo's official privacy policy states that no personally identifiable information (PII) is intentionally harvested, and product data is anonymized before inclusion in reports. The bot does not contribute to training generative AI models; its outputs are used solely for business dashboards and API feeds.

⚙️ Rate Limiting Policy

Despite its legitimate nature, katatudo-spider is rate-limited by many webmasters because its aggressive crawling cadence on large product catalogs can spike server CPU and database load. A threshold-based blocking policy (e.g., allowing 100 requests per minute per IP) is a pragmatic approach to preserve site performance while still permitting the bot to gather essential commercial data.
