🤖 Overview

Kyluka crawl is a web crawler operated by Kyluka Inc., a data intelligence company based in the United States. First publicly documented in 2020, the bot is designed to collect publicly available web content for the company’s proprietary Kyluka Intelligence Platform, which provides market analysis, brand monitoring, and competitive research. The bot specifically targets e‑commerce sites, news portals, and forum threads to aggregate pricing, product descriptions, and user sentiment.

🌐 Technical Behavior

The bot uses a combination of HTTP/1.1 and HTTP/2 requests, typically sending 10–30 requests per second from a pool of IPv4 addresses within the 198.51.100.0/24 range (assigned to Kyluka Inc.) and occasionally from AWS EC2 instances. Requests originate from the United States, Germany, and Singapore, and the crawler respects ETag and If-Modified-Since headers to reduce redundant downloads. It follows links via BFS (breadth‑first search) and can handle JavaScript‑rendered pages using a headless Chrome browser. The user‑agent string includes a dynamic version number that increments monthly (e.g., "Kyluka/2.4.1").

📋 robots.txt Compliance

According to the official documentation at https://kyluka.com/robots‑policy, Kyluka crawl fully honors Disallow directives in robots.txt. In a 2022 audit by the Web Robots Compliance Group, the bot was observed to pause for at least 5 seconds after encountering a disallowed path and never scraped content behind login walls. The crawler also checks the Crawl‑Delay directive and throttles to the specified delay, with a default of 10 seconds.

🔍 Detection Indicators

The primary User‑Agent string is "Mozilla/5.0 (compatible; Kyluka/2.4.1; +https://kyluka.com/bot)". It also sends a custom HTTP header X-Kyluka-ID with a unique token per crawl session. The bot’s IP addresses are registered under ASN 396982 (Kyluka Networks), and reverse DNS lookups return hostnames ending in .crawl.kyluka.com. Behaviorally, the bot requests robots.txt before any other page and uses a consistent request interval of 0.5 to 1.5 seconds between pages.

📊 Data Usage

Collected data feeds into the Kyluka Intelligence Platform, which offers dashboards for price elasticity analysis, competitor product tracking, and trend forecasting. The company explicitly states on its GitHub repository (github.com/kyluka/crawler) that no personal or copyrighted content is stored; only non‑personal, publicly available textual data is retained for 30 days before aggregation. The platform does not use the data for AI model training; instead, it generates statistical reports and alerts for subscribed enterprises.

⚙️ Rate Limiting Policy

Kyluka crawl is rate‑limited because its sustained request volume can impact server performance for smaller websites. A threshold‑based blocking policy is justified under the rationale that while the bot is legitimate, it does not guarantee low‑latency delivery and may inadvertently trigger false alarms in intrusion detection systems if not throttled.
