Pylets is a fast, lightweight, aspect-oriented Web framework built on mod_python and Apache. It uses Apache logs (and more Apache configuration in the future.) It can use Python objects, packages, and modules, or whatever the programmer wants. Pylets are also template-agnostic. With the debug switches off, and caching turned on, Pylets are less than 2x slower than serving static pages. The package comes with ORMit, a lightweight DB-API 2.0 connector-compatible object relational mapper.

Roundhouse is a modular J2EE application platform that allows applications to combine Struts modules, JSR-168 portlets, and Web services into a single application. It is intended to take the drudgery out of new J2EE application development by providing existing user and security architecture, navigation, and logging although it can be used standalone with no additional development. It ships with forum and blog modules along with several handy portlets which essentially make it a a portal based blog and forums application. The architecture is Struts-based and includes a Struts-based JSR-168 Portlet container. Developers extend Roundhouse by creating new standalone modules which can be independently developed without mucking around in the Roundhouse codebase and merged with Roundhouse and any number of other modules at build time. Modules can be created, packaged as MARF files, and redistributed.
