SPIP

SPIP is a self‑hosted, open‑source publication system designed for collaborative web authoring and multilingual sites. It provides a web‑based interface that lets multiple contributors create, edit, and manage content without requiring programming knowledge, and it supports a wide range of languages out of the box.

The software targets a variety of web projects—associative, institutional, personal, or commercial—where ease of use and collective workflow are priorities. Its GPL‑3.0 licence ensures that the code remains free and can be modified or redistributed by anyone, and the community maintains documentation, translations, and support through mailing lists, forums, and events.

Since its inception in 2001, SPIP has been adopted by tens of thousands of diverse websites, reflecting its stability and the active involvement of a global user base that contributes to its development and localization.
