Built-in Image Resizing

Upload an image, and it's automatically rescaled to a variety of sizes, ready to be used in your content. No Photoshop needed.

Look Your Best

Plone is easy to theme. It can seamlessly blend with your existing look, or allow you to create a bold new style that’s all your own.

Make your business processes part of the document workflow — complemented by fool-proof security management.

Speed and Scalability

Comes out-of-the-box with clustering capability and intelligent caching proxy integration.

Security and Flexibility

Fine-grained role-based security model secures your content. Plone's sandbox architecture ensures that even if your system should be compromised, intruders will not have access to your server or your network.

Syndicate and Aggregate

Smart folders and smart updates. Plone automatically produces RSS feeds from folders, search results and more — the ideal way of staying on top of the information explosion and customize information delivery.

Outstanding Search Engine Visibility

100% valid XHTML and CSS keeps search engines and web browsers happy. Plone sites are consistently ranked well in Google search results.

Plays Well with Others

LDAP, SQL, SOAP, Web Services (WSDL) and WebDAV — Plone works with them all.

Pluggable Authentication

Easy integration with LDAP, Active Directory and SQL databases. You name it, Plone talks to it.

Supported

World-class Support

Whether you use the online documentation, mailing lists and chat rooms — or the services of the hundreds of companies around the world that support Plone — you're never alone.

Open Source, Open Standards

Plone is available under the same open source license as Linux, and uses the open source Python programming language and Zope application server. This avoids vendor lock-in, expensive licenses, and gives you a predictable future — and the freedom to innovate.

Great Documentation, in Print and Online

Currently, there are five published books about Plone, which have been translated into German, Japanese and several other languages.

Innovative and Extensible

Hundreds of add-on products are available — forums, issue trackers, blogs and collaboration tools.
