Omeka Classic review 2026: free open-source CMS for digital collections and exhibits from George Mason University. Features, hosting options, and alternatives.
Omeka Classic is a free, open-source content management system built specifically for publishing digital collections and online exhibits. Development began in 2007 at the Center for History and New Media at George Mason University (renamed the Roy Rosenzweig Center for History and New Media, or RRCHNM, in 2011), with the first public release in February 2008.
The platform was created to give museums, libraries, and archives a free, standards-based way to publish collections online with an administrative interface as simple as blogging software, at a time when few affordable alternatives existed for cultural heritage institutions.
Omeka Classic catalogs items using the Dublin Core metadata standard by default, with customizable item types and unlimited metadata fields to fit different collection needs. Its Exhibit Builder lets curators arrange items into narrative, multi-page online exhibits without writing code.
A plugin and theme ecosystem extends core functionality with features like geolocation and mapping, PDF and document embedding, and custom site design, while its single-site architecture keeps setup and administration relatively simple compared to multi-site platforms.
Omeka Classic itself is completely free and open source; the software can be downloaded and self-hosted at no cost, provided the user supplies a compatible PHP/MySQL web server.
For institutions that do not want to self-host, RRCHNM offers a separate managed hosting service, Omeka.net, with annual plans including a free tier and paid tiers such as Plus ($35/year), Silver ($75/year), Gold ($350/year), and Platinum ($1,000/year), which scale by storage, number of sites, and available themes and plugins.
