🤖 Overview

hslide is a legitimate web crawler operated by Hslide Inc., a company that provides website change monitoring and alerting services. Its purpose is to periodically crawl designated web pages to detect content modifications and notify subscribers. The bot feeds data into the Hslide platform for real-time monitoring of competitive intelligence, regulatory compliance, and content freshness. Official documentation at hslide.com confirms its non-malicious nature.

🌐 Technical Behavior

Hslide employs scheduled crawling at user-defined intervals, from minutes to days, making HTTP/HTTPS requests at a moderate rate of roughly one request per 10–30 seconds per monitored URL. It uses IP addresses from cloud providers like AWS and Google Cloud, and identifies via User-Agent hslide/1.0 or hslide. The bot does not execute JavaScript or load external resources, focusing purely on raw HTML. It includes a From header with contact information, as noted in its technical documentation.

📋 robots.txt Compliance

According to Hslide’s official robots.txt policy page, the crawler fully respects Disallow and Crawl-delay directives. Webmaster reports and public bot listings confirm consistent adherence to these rules, making it a well-behaved agent that can be managed via standard robots.txt.

🔍 Detection Indicators

The primary User-Agent string is hslide or hslide/1.0. Additionally, the bot sends a custom X-Hslide-Request header containing a unique request identifier. IP ranges are listed in public databases such as bot.inc and can be matched to known cloud providers.

📊 Data Usage

Collected page content is used solely to generate change alerts for Hslide customers. No data is sold, shared, or repurposed for AI training or search indexing. The service stores only diffs and does not retain full page content beyond comparison needs, as per their privacy policy.

⚙️ Rate Limiting Policy

Rate limiting is advisable because hslide can send bursts of requests when monitoring many pages. A threshold-based block (e.g., >100 requests per minute per IP) is a practical policy to protect server resources while allowing legitimate monitoring activity.
