The Sakai Collaboration and Learning Environment (CLE) is a Java-based, service-oriented web application that provides a variety of capabilities supporting teaching and learning, portfolios, research, and ad-hoc project collaboration. The Sakai CLE is typically deployed using Apache Tomcat as its servlet container and scalability is achieved by running multiple instances of Tomcat in a clustered environment, each deploying a copy of the Sakai CLE. It integrates with a variety of external authentication services including CAS, Kerberos, LDAP, Shibboleth and WebAuth. A single database, usually MySQL or Oracle, provides a transactional store of information while file storage is typically delegated to NAS or SAN solutions. In most production settings, the Sakai CLE relies on a back-end student information system (SIS) to provide it with student and course information, which the Sakai CLE consults via provider APIs.

The Sakai CLE 2.8 release builds on previous releases by refining and stabilizing the 2.x feature set. It offers dozens of new features and improvements to key areas like accessibility, internationalization, performance, and security.
