Lone Wolf Development, creators of the Army Builder and Hero Lab programs, has been working for a few years on Realm Works, a tool for G Ms who want to track the information of a campaign and its world, complete with cloud storage of data and selective revelation of information to players. They have launched a Kickstarter project to secure further funding, in particular for the resources to run the cloud servers.
