I am looking for a simple python web framework which runs both as standalone and on Appengine.

I would like to write the app in such a way that i can switch between standalone and Appengine based on the deployment configuration. Standalone will be using RDBMS.

When i checked web.py looked simple and promising. I have the following questions:

  • Does web.py work well on Appengine?
  • Is there any major known gotchas?
  • Can you share your experience with using web.py on Appengine?
  • Any suggestions to achieve the above mentioned goal is appreciated.

    Does web.py work well on Appengine?

    Yes it does work pretty well, it’s compact and very easy to use.

    Is there any major known gotchas?

    Web.py does not offer any Data Abstraction Layer compatible with GAE; that means that in order to switch from a RDBMS to a NoSQL database, you have to create by yourself a layer above both the web.db database API and the Google App Engine datastore API.

    Can you share your experience with using web.py on Appengine?

    I have deployed a couple of simple applications with web.py on top of GAE and other several pet projects with Sqlite as database; here a mini review.

    Any suggestions to achieve the above mentioned goal is appreciated.

    If the switch from Appengine to RDBMS is your primary concern, have a look to web2py.
    Although with some limitations, to the best of my knowledge is the only one Python web framework GAE friendly that offers a DAL above the App Engine Datastore and other several RDBMS solutions.
    Switching from one db to another is just a matter of initializing the DAL with the proper connection string:

    db = DAL('sqlite://storage.db')
db = DAL('mysql://username:password@localhost/test')
db = DAL('gae')
