It is based on WSGI and utilizes the Paste library. This allows it to be deployed in various ways, including CGI, FastCGI, SCGI, mod_python and as standalone HTTP server.
This is not a full-stack framework that requires specific external components to be used with. Instead, any desired component should be easy to integrate into Upraise, including template engines (e.g. Genshi, Mako, or Jinja), database abstraction layers/ORMs (e.g. SQLAlchemy, Elixir, or SQLObject), URL dispatchers (e.g. Routes, selector, or Upraise's own, very simple dispatcher), authentication and authorization mechanisms (e.g. AuthKit, or barrel), i18n toolkits or whatever other component one might wish to make use of.
Not to mention lots of WSGI middlewares that are available, although spread over multiple packages and sometimes redundant.
Upraise provides a basic, flexible framework that does require some better understanding of the components desired to be used, but comes without the overhead and maybe unsatisfying preselection that full-stack frameworks like TurboGears, Django and, although to a lesser extent, Pylons imply.
