Metadot Portal Server is a leading open source portal system. Released in April 2000, it revolutionized the way complex websites are built by giving easy-to-use tools to non-technical users allowing them to create powerful database-backed websites without having to involve a webmaster or the IT department.

Its architecture makes it extremely easy to customize and deploy. It provides collaboration and content management. Typically it is used to create web portals, intranets, extranets, organization and project websites.
