🤖 Overview

Galaxybot is a web crawler operated by Galaxy AI Inc., a company specializing in large language model development. First documented in early 2024, its primary purpose is to systematically collect publicly available web content for training and improving Galaxy’s proprietary AI models, including chatbots and text-generation systems. The bot feeds data exclusively into Galaxy’s internal training pipeline and is not used for search indexing or advertising.

🌐 Technical Behavior

Galaxybot employs a breadth-first crawl strategy, sending HTTP GET requests with a default delay of 2–3 seconds between pages. Official documentation from Galaxy AI (galaxy.ai/crawler-policy) indicates it uses rotating IP addresses drawn from the Amazon Web Services (AWS) and Google Cloud Platform (GCP) ranges, primarily US‑based. The crawler respects Cache‑Control and ETag headers to minimise redundant downloads, and it follows 301/302 redirects to canonical URLs. Requests are made over HTTP/1.1 and HTTP/2, with a maximum concurrency of 10 simultaneous connections per domain. Galaxybot also sends a User‑Agent containing the crawler version and a contact email () for site owners.

📋 robots.txt Compliance

Galaxy AI’s policy (galaxy.ai/robots‑txt) explicitly states that Galaxybot honors Disallow directives in robots.txt. Independent analysis from BotCheck.io (2024) confirmed that the bot respects both per‑path and wildcard rules. It also reads Crawl‑Delay directives and will slow its request rate accordingly. No confirmed violations have been reported in public security advisories.

🔍 Detection Indicators

The primary User‑Agent string is Mozilla/5.0 (compatible; GalaxyBot/1.0; +https://galaxy.ai/bot). A secondary variant GalaxyBot/2.0 is used for deep‑page crawling. Behavioral fingerprints include a X‑Galaxy‑Crawler header set to true and a typical request interval of 2–3 seconds. The bot does not spoof browser user agents; it always identifies itself as a crawler.

📊 Data Usage

Collected content is stored in Galaxy’s private data lake and used exclusively for training large language models (LLMs). According to Galaxy’s privacy policy (galaxy.ai/privacy), raw HTML, text, and metadata are processed, but personally identifiable information (PII) is stripped during ingestion. The data is not sold or shared with third parties and is retained for the duration of model training cycles, typically 6–12 months.

⚙️ Rate Limiting Policy

Although legitimate, Galaxybot can issue thousands of requests per hour across a site’s public endpoints, which may degrade performance for smaller servers. Rate limiting is recommended to protect server resources while still allowing the bot to complete its crawl within a controlled timeframe, balancing data collection with operational stability.
