Developing Free and Open Source software takes a lot of time. In order for the development of Fidus Writer to be sustainable, I need to ask ask those interested in Fidus Writer continuing to contribute. Fidus Writer has been developed since 2012 and is licensed under the the open source AGPL-license, free for anyone to use and install as they see fit. There have also been other projects that came out of Fidus Writer, such as the diffDOM library, which I still maintain.
While fixing bugs is free, working on adjusting Fidus Writer to fit into your site or custom development of proprietary features that will be unique to your site is offered at a rate of 150 Euro/hour. Features that will be made available under an open license can be developed at a discount. Please contact me for details.
