What is Plone?
Plone is a powerful and flexible, enterprise-quality content management system that is easy for developers to download and install, and easy for end-users to use. Plone lets non-technical people create and maintain website content using only a web browser. Plone offers a rich set of capabilities for public websites, private intranets and collaborative workspaces.
Plone is among the top 2% of all open source projects worldwide, with 200 core developers and over 300 solution providers in more than 50 countries.
Plone has been actively developed since 2001, is available in more than 40 languages, and has the best security track record of any major CMS.
Plone’s codebase and intellectual property is owned by the Plone Foundation, which is a non-profit organization where donations are tax-deductible (at least in the US).
