Oscailt is an independent media centre content management system developed by the Indymedia Ireland Tech Group, and written using PHP and MySql. The word "Oscailt" is an Irish word meaning "open" and is pronounced kind of like us-kilt or us-cult or us-culch depending upon your accent.


A comphrehensive feature list for Oscailt is maintained here including release notes for the latest releases which document the new features added in each release.

As of Mar 2024 the Oscailt HTML User Guide v1.8 has been updated for the latest release. The user guide is available from the Oscailt sourceforge where it is checked into svn source control system. It also comes shipped with the latest release of Oscailt v4.3.1

An Install and Configuration Guide is now available as of June 2019 and will be included in all releases from v3.8 onwards.

There is also some design documentation on Oscailt available here


Oscailt is freely available to use and download under the terms of the GPL.

Oscailt is a continually evolving codebase and all contributions are welcome. SVN access to the codebase is available at Sourceforge.net

All discussion concerning Oscailt takes place on the Oscailt Mailing List. Please subscribe if you wish to play a part in Oscailt's future development. Unfortunately the mailing list was hosted on the main Indymedia servers and all their lists were shutdown in 2015. For any Oscailt related questions, direct them to: techies at indymedia dot ie

Bear in mind when submitting code that the primary focus of Oscailt is to serve the needs of Indymedia Ireland and this will be the primary factor in deciding whether to integrate submitted code. That said, the needs of Indymedia Ireland probably overlap a great deal with the needs of other independent media centres, so the code should be generally useful. And even then, as the code is open source you are free to create and maintain your own derivative branch if you so wish.

This number has varied over the years and unfortunately has dwindled from a high of approximately 15 IMC sites at the height of the Indymedia to the present much reduced set now
