Some developers trying to easy the use of the system as a whole have created Virtual Machines with everything you need already configured. It is the case of:
- Ginga-NCL Virtual Set-top Box is a Linux-based VMWare image with including Ginga-NCL. (It looks outdated!)
- GingaAIO is a virtual machine for execution and authoring of NCL application. Unlike Ginga-NCL Vittual Set-top Box, gingaaio also includes a graphical environment to easy the creation and execution of NCL applications. (It looks outdated!)
- Ginga CDN

- GingaBuild is a shell script program to install and configure a Ginga development environment. (It looks outdated!)
- NCL Composer is an extensible authoring tool to support mixed (textual and visual) authoring of NCL applications.
- NCL Eclipse is an Eclipse plugin aware of NCL syntax and elements relations.
- ISB Designer is an authoring tool with the aim of supporting interactive storyboards. The tool can export NCL documents.
- Cacuriá is an authoring tool suporting the creating of hypervideo-based learning objects, and that can export to NCL.
- NCL/Lua plug-in for Gedit
- NCL/Lua plug-in for Latex
- Berimbau iTV Author was created focused on designers and media professionals, allowing them to create interactive applications without programming knowledge. The tool is free to use (but it is not open-source).
- Celula is an authoring tool developed by INCoD focused on creating interactive content for digital TV.
- CreaTVDigital is a tool aiming at easing the development of interactive Digital TV application by media professionals. It follows a WYSIWYG approach and does not require authors to know NCL or Lua.
- Iris (Cpqd) is a graphical tool that allows for content producer to create interactive multimedia application without the necessity of coding.
- Creative-NCL is a web-based tool that allows for the creation of NCL documents through visual abstractions.
- Guri Project FIXME.
- NEXT is an authoring tool for NCL documents using templates. It is based on plugins, where each plugin provides a different view of the document (spatial, textual and structural) or a facility for creating document parts (connector plugin). NEXT allows the author to choose a template from a template base and fill it, through a set of screens, in order to create an NCL document (available at request).
- STEVE is an authoring tool designed based on commercial tools for creating multimedia presentations. It allows the author to create an NCL document from its temporal view. STEVE allows creating temporal relations among media objects, including interaction relations.
- Ginga Studio FIXME.
- NCL Validator --- Java is a Java-based validator for NCL documents. It is currently integrated into NCL Eclipse and nclvs.
- NCL Validator --- C is a C-based software for incremental validation of NCL documents. Currently, its source code is integrated into NCL Composer.
- nclvs (NCL Validator Service) is an online validation service for NCL documents.
- ncl-inspector is a rule-based critique system to evaluate NCL applications code quality automatically.
- aNaa4Web is an interface built upon the aNaa API.
- Property Editor is an editor for creating temporal properties to be validated in an NCL document and performing the validation.
- LuaTPL enables Lua to be used as a template specification language in a similar way to how PHP, ASP, JSP, etc. are integrated to HTML. In special, the use of Lua as base for template specification in the scope of Ginga-NCL also allows for processing this templates in the client side, since Lua is a standard for developing iDTV applications for Ginga-NCL.
- TAL (Template Authoring Language) is an authoring language for hypermedia document templates.
- XTemplate 3.0 is a language to create composite templates for NCL. The composite templates describe, in a generic way, the behavior of an NCL context.
- EDITEC is an authoring tool for XTemplate 3.0 templates.
- LUAR is a framework for agile development of applications written in NCL/NCLua for Digital TV.

- NCLuaSOAP is an NCLua module that implements the SOAP 1.1/1.2 protocol.
- aNa (API for NCL authoring) is an API for representing NCL documents through Java classes. Its purpose is to help programmers to create tools that manipulate NCL code.
- aNaa (API for NCL authoring and analysis) is an extension of aNa providing methods for performing document validation.
- NCLuaRSS-Reader is an RSS feed reader for Digital TV.
- JNS (JSON NCL Script) is an alternative syntax to write NCL documents. Instead of XML, JNS uses JSON. Additionally, JNS includes new features aiming at to improve reuse and easy programming. For instance, JNS allows inline declaration of descriptors, rules and regions in the document's body. (If you do not know what is descritor, rule, or region in the context of NCL language, please see the NCL Handbook.

- ncls3d is a lua script to convert an NCL application to its stereoscopic counterpart. The final application is ready to run on stereoscopic 3D displays. It allows both off-line conversion, and on-line (client-side) conversion---through an NCLua media object.
- Lua2NCL is a Lua-based API to create NCL documents.
