Stablecomparisonoverview
openDesk Edu combines 10 base services from openDesk Community Edition with 15 education-specific Beta services and 11 scientific computing tools from the Collab Services suite, delivering a comprehensive digital workplace tailored for schools, universities, and research institutions. All 36 services integrate through Keycloak SSO (SAML 2.0 / OIDC) and are accessible from the unified Nubus portal.
Services within the same category may serve as alternatives to each other — for example, you can choose between Jitsi and BigBlueButton for video conferencing, or between OX App Suite, SOGo, and Grommunio for groupware. Beta services are fully functional but still under active development; they may change in future releases. Planned services are on the roadmap and not yet available in production.
