Elgg review
A flexible self-hosted foundation for groups, forums, and private communities.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Elgg is an open-source, self-hosted social networking engine for organizations, campus networks, online communities, and other socially enabled websites. It combines user profiles and avatars with public or private groups, group forums, pages, messageboards, file repositories, activity streams, RSS feeds, notifications, authentication, and administration. Fine-grained access control lists support private spaces and controlled content sharing, while moderation tools and custom domains fit sites that need their own operating environment. It is best suited to teams that want to shape the community experience rather than adopt a fixed hosted network.
The open-source model gives Elgg a different cost structure from subscription community products: the software itself is available as an open-source project, while the site operator manages the infrastructure on which it runs. That approach can suit organizations with technical ownership of deployment, administration, authentication, permissions, themes, and ongoing maintenance. It is less suitable for buyers seeking a packaged service with a managed operating layer. Event creation, registration, RSVP, and attendee management are available through the Event Manager plugin, extending the platform without making event workflows part of the core installation.
Elgg’s strongest advantage is breadth within a self-hosted community foundation. Plugins and custom themes allow administrators and developers to adapt the experience, and the web services API supports external applications and mobile clients. RSS provides a straightforward feed connection, while Event Manager adds iCal export. The platform should appeal to organizations needing profiles, groups, private activity, forums, files, notifications, and access controls in one deployable system. Buyers who prioritize a broad ready-made integration ecosystem, a hosted service, or an all-in-one event product should consider a more specialized alternative.
