DemTools is a suite of free, open source software solutions developed by NDITech and distributed for supporting democracy building efforts around the world. The software includes contact management, issue tracking, crowdsourcing, election monitoring, open data, and petition development tools. These were built with the developing world in mind but can also be used in other contexts.
An associated DemTools Guide Book offers an overview of each of the suite of tools, including use cases, user consideration, technical specifications, security considerations, languages/translations, the type of support offered by the publisher, instructions for deploying and hosting the tools and case studies of the tools in practice.
The publisher also offers free and paid hosting service and technical support, but some resources and expertise will be required of the user for setup and ongoing maintenance of the tools.
