FavicoHub Research Crawler
You've reached this page because an automated request to your server came from this IP address.
What this is
FavicoHub is an independent security-research project. It builds a searchable index of website favicons (the small site-icon files browsers show in tabs and bookmarks) across a large, publicly-ranked list of domains. The index is used for research into shared hosting infrastructure, brand-impersonation detection, and phishing-cluster identification — sites that reuse the same icon file are frequently related, either legitimately (a shared CMS or hosting provider) or maliciously (a cloned phishing page).
What the crawler does
| Requests | A small number of lightweight HTTP requests per domain — primarily /favicon.ico and the declared icon links on the homepage. |
|---|---|
| Frequency | Each domain is visited on an adaptive schedule, generally no more than once every few days, and less often for domains whose icon hasn't changed. |
| Rate limiting | Requests are limited per host and globally; the crawler does not send bursts of traffic to any single server. |
robots.txt | Honored, including Crawl-delay. A disallow rule for this crawler's user agent is respected on the next visit. |
What the crawler does not do
- It does not scrape page content, text, or personal data.
- It does not attempt to log in, submit forms, or execute JavaScript.
- It does not probe internal or non-public infrastructure — it only requests what a normal browser visiting your public homepage would request.
- It does not resell or publicly redistribute raw crawl data; the index exposes icon-hash relationships and aggregate metadata, not scraped page contents.
How to identify this traffic
Requests from this project identify themselves with the following User-Agent, which links back to this page:
FavicoHub/1.0 (+https://crawler.favicohub.com/)
Opting out
Add a User-agent: FavicoHub disallow rule to your robots.txt
and it will be honored on the next visit. If you'd like your domain excluded
immediately, or removed from results that have already been indexed, contact
