* Works from the SDK or in production (great for advanced datastore management)
* Exceptions, modules, and types link to their own documentation on python.org
* Quick access to the datastore, application dashboard, and Google Analytics
* When in production, optionally returns HTTP 404 to non-authorized users (”cloaked mode”)

Google App Engine Backup and Restore (Gaebar)
Description: With Gaebar you can:
* Backup either your local datastore or a deployment environment datastore.
* Restore backups either to your local datastore (test with real data while developing), or to your app's deployment environment datastore. (You can restore into any app that you have admin access to and that has Gaebar installed, not just the one you backed up from. So, basically, you can have a separate Staging App to test with before updating your actual app.).

Virtual Proxy Economy
Description: The virtual proxy economy (VPE) is an open-source software representation of a real-world economic domain. The representation uses virtual actors (software objects) to serve as proxies for real-world economic actors. The virtual actors hide the complexity and diversity of real-world economic actors by providing a common and unified view of the economic actors at different levels of aggregation and abstraction. A virtual actor represents a real-world economic actor performing a specific role in a service domain. A service domain supports a particular user view and contains the virtual actors performing the role specified by the view. The role in turn defines the kind of stock and flow data and behavior to be associated with the virtual actors playing the role. The VPE provides eight service domains organized as a series and tightly integrated through software links connecting the virtual actors in one service domain to their counterpart actors in the prior and next service domains in the series. The integration of data follows from the integration of the service domains. The VPE serves as a centralized and unified data repository and processor implemented on a low-cost cloud computing infrastructure to ensure scalability and availability using the Internet and standard web browsers (see the work-in-progress VPE web site at http://ecoknowmics.appspot.com).

Description:
Generic Forward and Backward Bookmark paging for Google App Engine for Java.
At the present time, the Google App Engine does not provide a built-in pagination support. There are various methods how one can implement limited pagination manually, but writing the paging queries by hand can be tedious and error-prone. This project tries to alleviate this problem by providing an automatic way to generate appropriate paging queries from a base query, and then using these queries to page through the data.

Description:
The project uses Apache License 2.0. AEJTools provide a set of tools to remotely access the appengine datastore data. It can be used to run queries, store new entities or as a data import/export tool.
- It has a server module which provides a Rest style interface for the data and uses XML as the transport language. It is almost the Rest style equivalent of the Low level Datastore api.
- It also has a client module which implements DatastoreService, and PreparedQuery interfaces and allows access to the datastore remotely. Any calls made using these implementations actually runs on remote appengine server. The client module also makes use of Groovy interactive shell and this allows the user to use the shell like using the mysql command line client. Users can run queries, store new entities easily using the client.
- The server module is only accessed using HTTPS and by default it is only accessible by admin privileged users.

So basically it depends on what kind of deployment is needed for your application. It will work equally well with applications which are hosted on GAE as well as applications which are hosted outside. Since the container can be accessed via HTTP, it can very well support applications written in any language.
