Top 10 most popular sites running on Google App Engine

Checking whether a specific website is running on the Google App Engine is pretty easy (see "How to identify if a website is hosted using Google App Engine").

So what are some popular sites running on the Google App Engine?

I've compiled a list of what I believe are the ten most popular sites currently running on the Google App Engine. In this context the site's Alexa ranking is taken as a proxy for the site's popularity. Sure, Alexa is not a perfect indicator of popularity, but it is the best publicly available traffic data source there is.

Here is the list of the most popular site running on Google App Engine as of May 6, 2009:
Do you believe that I've missed a Google App Engine hosted site that belongs to the top ten list? Please leave a comment! Don't forget to specify the Alexa ranking of the site that you believe should be added to the list. Please also let me know of any false positives in the list above. Well, please let me know if the list can be improved in any way, shape or form.

Jaiku.com should probably be given a special mention. While Jaiku.com appears to be running on the App Engine platform I'd guess that Jaiku is running in a server environment that is separate from the standard public GAE environment. The CNAME setup of www.jaiku.com would support that hypothesis (CNAME jaiku.l.google.com instead of the standard GAE CNAME of ^(ghs|appspot)) . Does anyone know if that is the case? Please leave a comment.

I'll update this top list from time to time as I'm certain that a significant number of high-traffic sites will be migrated to GAE over the coming months thanks to the recently added support for Java (or more specifically Java bytecode).

  2. I thought Alexa ranks aren't that accurate in predicting site traffic since it counts visitors using the Alexa toolbar which AFAIK not many people use.

  5. @xAbhishek: That was true until roughly a year ago when Alexa added additional data sources, see this article.

  7. Alexa lumps together *.appspot.com to the aggregate rating for the entire appspot.com domain which has an Alexa ranking of 3192.

    Appspot.com subdomains (*.appspot.com) are used for GAE-hosted sites without a site specific domain name. These are usually sites under development or smaller sites.

  8. Are you sure about www.robtex.com? CNAME does not go to ghs.google.com, and /form returns an ordinary 404.

  9. @losjackal: It appears as if robtex.com has moved away from AppEngine. I'm sure it was on GAE - the site also featured the text "latest news: Mar 26: we are in the process of moving the site to google appengine.".
