Short answer
Calenco differs through its combination of sovereignty, documentation expertise, and functional coverage. It is a French CCMS developed by NeoDoc, a documentation engineering specialist since 2004.
The platform relies on open standards such as XML and DocBook, which supports long-term content durability and interoperability. It covers both technical documentation with Calenco Docs and field forms with Calenco Forms.
Calenco also offers hosting in France, GDPR compliance, an on-premise option, and project support. For demanding organizations, the value comes not only from the software, but from the ability to industrialize a complete documentation lifecycle.
