=== HelmaLib ===

*HelmaLib* is included with standard Helma installations and is a Javascript library considered to be of universal usefulness for all Helma application development. It consists of two modules, a core module that extends core Javascript prototypes and a "helma" module that contains additional prototypes, providing additional functionality not provided directly by Helma's core environment. 


=== Jala ===

*Jala|https://dev.orf.at/trac/jala* is an open-source collection of JavaScript modules for Helma Object Publisher, written and maintained by  ORF.at and licensed under the Apache 2.0 License. Jala modules include support for GNU gettext compatible internationalization, asynchronous request dispatching, HopObject collection rendering, and *much more|https://dev.orf.at/trac/jala/wiki/JalaModules*.


=== HelmaSwarm ===

*HelmaSwarm* is a tool to build Helma clusters, a group of Helma instances forming one virtual server. HelmaSwarm uses asynchronous JGroups communication to distribute/coordinate cache and session state.


=== HelmaGroups ===

*HelmaGroups|http://helma.org/stories/77390/* is a Helma extension that puts several helma servers into a group and makes them share data in their memory over the network. A new global object "group" is added to the scripting environment and all changes in that object tree are immediately replicated to all members.


=== Rhinola and mod_gcj ===

*Rhinola|http://mod-gcj.sourceforge.net/rhinola.html* is a very thin server-side JavaScript execution framework running on top of mod_gcj, a module for Apache to run Java code via GCJ directly within the web server. Rhinola is a fresh implementation of a Helma core and formed the basis for the development of the Helma 2.0 development branch.


=== Rabbit ===

*Rabbit* is a framework that provides a clean and simple way to script the object-data structure of a Helma application and automates the mapping of that object structure to a relational database, including the automatic setup of that database.


=== Warp ===

*Warp repository|http://helma.org/pipermail/helma-dev/2007-May/003571.html* is a repository providing virtual prototype directories and type.properties files based on existing database schemas. You need to have correct primary and foreign keys set in your database for this to work.


=== JavaScript Template Engine, Velocity and FreeMarker ===

A flexible templating engine that is written entirely in Javascript and is backwards compatible with Helma 1.5 skins and macros, but adds additional statements such as loops and conditionals. The *JavaScript Template Engine* is implemented as a library for Helma 1.5. It has not yet been updated to be compatible with the new features added to Helma 1.6 skins and macros.

For those looking for even more templating alternatives, Jürg Lehni also implemented two Helma extensions. *VelocityExtension|http://adele.helma.org/source/viewcvs.cgi/extensions/velocity/README.txt?rev=HEAD&cvsroot=hop* is a Helma extension that integrates Velocity, a  powerful  open source template engine into Helma and *FreeMarkerExtension|http://adele.helma.org/source/viewcvs.cgi/extensions/freemarker/README.txt?rev=HEAD&cvsroot=hop* is a Helma extension that integrates FreeMarker, another powerful open source template engine into Helma.


=== Gobi ===

A dynamic wikiesque web site framework built on Helma. *Gobi|http://gobi.helma.org/* aims to provide a platform for Wiki applications as well as applications including Wiki-like features and provides simple yet powerful base classes that can be extended to do any imaginable thing.


=== Twoday Antville ===

A feature rich, industry-proven blog hosting software based on Antville*Antville|http://antville. *Twoday|http://twoday.org/* is an expandable weblog hosting system built on Helma that has some of the software running at twodayfeatures of a full grown content management system.net, Antville scales very well up to several thousands of weblogs and is very easy to use while offering a german-speaking weblog lot of advanced features that make it even capable for hosting platform hosted and developed by Knallgrauother types of websites.

Knallgrau also offers an extended commercial version called *Twoday Media|http://www.knallgrau.at/solutions/socialsoftware/twoday-media*.


=== OpenMocha ===

A soft-coding web site framework built on Helma. *OpenMocha|http://openmocha.org/* web applications are written through a web-based interface that wraps pieces of server-side and client-side code around content objects. These behaviors are inherited by other child objects in the hierarchical content tree and can be overridden at any level.


=== AppJet ===

Another browser based soft-coding framework, offered as a hosting service.  The *AppJet|http://appjet.com/* site itself runs on Helma, providing the environment in which the apps are developed, while the resulting  apps themselves are served directly from a custom developed Rhino virtualization engine.


=== Chopper ===

*Chopper|http://blog.p3k.org/stories/3143/* is a client-side Javascript library that provides methods and features to emulate the Helma scripting environment on the client-side. It effectively allows you to write client-side applications the way you would write them on the server-side using Helma.


=== Junction ===

*Junction|http://code.google.com/p/trimpath/wiki/TrimJunction* is a Rails-like, offline-capable MVC framework that runs both client side on the browser and server-side on top of Helma. It synchronizes code and RDBMS between the two sides. On the client-side it leverages Google Gears.


=== Axiom ===
*Axiom|http://axiomstack.com/about/* is a commercial fork based on Helma, a framework with a JSR-170 compliant embedded database, support for TALE templates and many other out-of-the-box features.


=== CouchDB ===

Joshua Paine ported the *CouchDB javascript lib|http://grazia.helma.at/pipermail/helma-user/2007-December/007244.html* to run on the Helma server-side. CouchDB is a document database server, accessible via a RESTful JSON API, which is what this Helma server-side lib leverages.
