update : 23/12/2020 SPIP

Originally, in 2001, SPIP was primarily used by web surfers to manage their own personal websites and on associations’ websites. It is now used by private and public organisations of all sizes, to manage their professional websites. 

SPIP enjoys a strong reputation, particularly in France. This success can be attributed to the product's simplicity, in terms of use as well as deployment and adaptation. The flip side of this simplicity is that SPIP has a number of limitations in respect of certain key content management functionalities (e.g. structured content and workflows). It is, however, remedying these gaps from one version to the next. For example, version 3, released in mid-2012, offers a new management interface (rewritten on its own framework), stronger modularity (with better APIs) and numerous enhancements and developments like a data loop that can display all sorts of external data (from .csv, .xls, Google doc files and more).
SPIP is an open source project created in France (and licensed under the GPL). Its community is relatively active, with multiple versions released each year and hundreds – if not thousands – of members.
SPIP’s software is written in PHP using MySQL, PostGreSQL and SQLite databases.
