Easy to use

Easy to use

Silva makes it easy and efficient to create and publish content for the web.

Updating content, managing content, using the editor, previewing your work, organizing your content, the publication workflow... everything feels fast and intuitive, saving you time and energy.

Versioning and workflow

Versioning and workflow

Versioning was build into Silva since it was created, this makes it robust, simple to use. Separation between authors who create content and editors who approve content, avoiding a single-person bottleneck without the loss of editorial control. No need to worry losing your content as an author, and no need to worry that unapproved content gets published.



The Silva content management user interface is translated in the language that a user sets in his Preferences. Authors can write content in the audience language and edit in their native language. This is very handy for international organizations that require collaboration between employees that have a different native language.



Up to date user documentation at your finger tips, that you can install while setting up your Silva site.

One central website having all the latest documentation by version number, no need to search the web and find outdated documentation confusing you and make you waste valuable time following outdated instructions.

Export and Archiving

Export and Archiving

Export and import valuable content across multiple Silva sites by making a zip which will also contain all required assets. This can be used as a local backup or for duplicating content to another Silva site.

Create a local HTML export for offline presentations and other offline activities.
