Collapsify
What is Collapsify?
About
Collapsify is a Cloudflare internal service that crawls customer error pages to serve them directly from Cloudflare's edge network. This improves performance by caching and delivering error pages from edge locations rather than origin servers. You can see how often Collapsify visits your website by setting up Dark Visitors agent analytics.
Expected Behavior
Fetchers visit websites on-demand. They're normally dispatched by apps to present metadata about a link (e.g. the title and thumbnail image) to a user.

Should I Block Collapsify?
Probably not. If you block a fetcher, it won't be able to fetch the metadata it needs to display a link preview. Fewer people will click on the link to your website without this.
How Do I Block Collapsify?
You can block Collapsify or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
