My projects: MetaJS - logos-oriented lisp compiled to Javascript, universal communication protocol Coect.net.
I use Javascript and Python.
Before December 6, 2012 Appengine users used Google Apps Standard for mapping custom domain to appid.appspot.com for free (or price of using custom domain was included into App Engine regular price).
On December 6, 2012 Google canceled Google Apps Standard price plan: http://googleenterprise.blogspot.ca/2012/12/changes-to-google-apps-for-businesses.html
However in App Engine control panel on Domain Setup Tab is still stated: "If you do not have a Google Apps domain, App Engine users can sign up to a single-user Google Apps Standard account for free."
Link to "Google Apps Standard" from this page don't work ATM.
If I just need to map my custom domain to the site hosted on App Engine and don't need other Google Apps services, will I need to pay $50/year for CNAME domain alias for my app?
Asked same question in app-engine community on SO:

Often we receive tweets with which we don't agree and we want to poll our followers about their opinions. Ideally we should be able to attach a poll to a tweet without leaving Twitter. With this thoughts in mind I made PollAll.me. It allows to attach a poll to a tweet as easy as send a tweet.
If you don't agree with a tweet, just type @pollall ? in your reply and receive a poll with default question and quotation of the replied tweet. Or you can provide your own questions and answers for a poll, just reply with a tweet like:
@pollall Will Java replace C in 5 years: Yes, No, Never?
PollAll.me runs on Google App Engine. I deployed three projects on GAE already and I like it very much for the robustness and stability. Server side is wrote on Python with Jinja2 as template engine. On client-side I use JQuery, Bootstrap and CanJS, fantastic JavaScript framework to which I switched after using Backbone.js.
