CubicWeb is a semantic Web application framework that empowers developers to build Web applications by reusing components (called cubes) and following the well known object-oriented design principles. Its main features are: an engine driven by the explicit data model of the application; a query language, RQL, similar to W3C’s SPARQL; a selection+view mechanism for semi-automatic XHTML/XML/JSON/text generation; a library of reusable components (data model and views) that fulfill common needs; the power and flexibility of the Python programming language; and the reliability of SQL databases, LDAP directories, Subversion, and Mercurial for storage backends.
Dynamic Form is a Python request abstraction library that lets you write one request handler that will run on multiple Python Web frameworks (such as Django and Google's AppEngine). This allows you to create pages and apps once and use them on multiple projects without concern about which framework is being used. Additionally, it makes AJAX easy. Simply adding nested request classes allows you to define AJAX handlers that can easily be refreshed both sever-side and client-side.
GUI Builder is a drag and drop interface for creating WebElement User Interface (WUI) templates that can be used as the foundation of a responsive Wep app. It simplifies the process of designing applications, and encourages separation of the logic and view. It is part of the WebBot Web development framework, which makes it possible to build Web apps in a similar fashion to Qt/KDE apps.
PySite is not a CMS in the traditional sense. Rather, you manage the contents of a Web site via a file manager interface, which gives you access to all settings (pages, styles, plugins, etc.). Compose your pages with Jinja templates, and edit your code comfortably with syntax highlighting in the ACE editor. You may write your stylesheets in Sass and let the integrated compiler write CSS files. PySite also contains a facility to manage virtual mailboxes, in case you maintain your own SMTP and IMAP server, e.g. with Postfix and Dovecot.
Pyramid is a small, powerful, and flexible set of Web development components that supersedes both Pylons 1. 0 and repoze.bfg. It can be used to write clean and fast applications, and supports plugging in a variety of components like storage, templating engines, and authentication mechanisms.
gauger is a lightweight performance recording and monitoring tool, aimed at detecting regressions (or sudden impovements) in any measurable metric. It is mainly intended for software development, but can be used for other purposes such as network monitoring or meteorological logging. It collects measurments made by a number of clients (potentially behind firewalls) on a central server and allows you to visualize and analyze the data later. It offers a central log server, Python, Java, and C interfaces for the clients, and a Web interface to browse the data. It allows you to view graphs of the data per host or per metric, selecting the desired ranges and sizes, and allows you to download the data in a gnuplot script for further processing.
Pagekite is software to make servers on "localhost" visible to the wider Internet. It can be used by Web developers to show off their works in progress to clients or colleagues, embedded developers who need direct access to devices in the field, or as an alternative to dynamic DNS for individuals/hobbyists who would rather host their own content than rely on 3rd party hosting. It creates and maintains a tunnel between your server on localhost and a remote "front-end" (a reverse proxy). Only the front-end has to have a visible IP address; the server itself can reside on a heavily firewalled computer, a mobile device, or even an anonymous node on the Tor network.
