What is qcbot?

The qcbot is the dedicated crawler for the QUIC.cloud platform, designed to facilitate various performance-enhancing services for websites using the LiteSpeed Cache plugin. Unlike general-purpose search crawlers, this bot operates on a per-site basis to retrieve specific assets—such as images for optimization or page content for CSS generation—and returns the processed data to the user's server. It acts as a bridge between the website and QUIC.cloud's remote processing infrastructure.

Helpful — This bot is a functional component of the QUIC.cloud performance suite, enabling essential site optimization tasks requested by the site owner.

What we read

Why it crawls your site

The bot crawls websites to perform off-server processing tasks that would otherwise consume excessive local server resources. By fetching assets like images or stylesheets, it allows QUIC.cloud to optimize them remotely and notify the site when the improved versions are ready for deployment. Site administrators can verify the bot's legitimacy by checking its user-agent and ensuring that requests originate from the official QUIC.cloud IP range, which is recommended for allowlisting to ensure service continuity.

Block or allow qcbot

Block it

Add a Disallow rule for qcbot in your robots.txt file. You can also block at the server level using your web server configuration or CDN firewall rules to filter requests matching the user-agent string.

# Block qcbot from crawling your entire site
User-agent: qcbot
Disallow: /

# Allow qcbot full access
User-agent: qcbot
Allow: /
Allow & verify

Ensure your robots.txt allows qcbot. Verify requests by checking the user-agent string.
