Crawler

CombupBot

CombupBot is the crawler behind Combup, a fashion search service that helps shoppers compare products across stores. It reads public product information so people can find an item and then buy it on the store's own website.

How it identifies itself

Mozilla/5.0 (compatible; CombupBot/0.1; +https://combup.com/bot)

We don't imitate a web browser, and we don't try to get around bot protection, CAPTCHAs or access controls. If a site challenges or blocks our requests, we stop.

What it reads

How fast it crawls

At most about one request per second per site, usually far less. We honor Crawl-delay and slow down automatically when a site responds slowly or returns errors.

How to limit or block it

CombupBot follows the Robots Exclusion Protocol (RFC 9309). It obeys rules written for CombupBot, and otherwise the rules for *. To block it completely:

User-agent: CombupBot
Disallow: /

To ask it to slow down:

User-agent: CombupBot
Crawl-delay: 10

How products appear on Combup

Each product links to the store's own page, where the purchase happens. Combup shows the store's name as text and doesn't use store logos.

Remove your store from Combup

To have your products removed from Combup, email [email protected] from an address at your store's domain. We apply the request within 48 hours, and CombupBot stops visiting your site. Blocking CombupBot in robots.txt also works; the change is picked up the next time it reads your robots.txt, at most one day later.
