Dotclear is an open-source blog publishing application distributed under the GNU GPLv2. Developed by Olivier Meunier in 2002, Dotclear has attracted a solid team of developers. It is relatively popular in French-speaking countries, where several major blogging platforms use it (Gandi Blogs, Marine Nationale, etc.).

Dotclear's proposed aim is to develop software that fully respects web standards based on open-source solutions[buzzword], with multilingual interface and publishing capabilities. It is written in PHP.

Notable features include handling many blogs, using Wiki or XHTML syntax for entries, adding pages independent from the flow of access, and supporting several database types: (MySQL, PostgreSQL, SQLite).
