Distance learning has not been widely used for several objective reasons in many countries until recently | mainly because of the underdevelopment of the technical means of new technologies. At present, technical premises have been created for the widespread use of distance learning in education and, with the restrictions imposed by Covid, the dynamics of their implementation was surprising. E-learning software is represented by both simple static HTML pages and complex learning management systems (LMS), and learning content management systems (LCMS) used in computer networks. The further development is related, also, to the possibilities o®ered by the cloud environment. Successful implementation [1] of e-learning is based on the correct choice of software that meets the speci¯c requirements and objectives of the organization. This article proposes an analysis of the usability and software functionality of the Open Source E-learning Platforms. Based on the survey of the state-of-art [2] science research we can highlight some of our results: { a series of criteria for analysis of the LMS platforms were proposed: ± Functionality, ± Reliability, ± Stability, ± Availability of content development tools, ± SCORM support, ± Knowledge testing system, ± Easy to use, ± Modularity, ± Ensuring access, ± Scalability and extensibility, ± Multiplatform LMS. { most popular distance learning platforms were analyzed, { assessment of current LMS Integration capabilities was done. LMS are commonly used for management of online learning activities inside single or many courses. Modern trends in the development of Open Source LMS/LCMS are aimed at universalizing and increasing the functionality of systems. Most of open source systems have multiple platforms and are not related to speci¯c operating systems or speci¯c web browsers. In terms of their capabilities, the most advanced systems are not inferior to their commercial counterparts, and some are even superior. They are usually rich enough in di®erent tools and options in order to allow modern interactive learning environment. A wide-range comparative analysis of 8 electronic learning management systems was presented. All of them support the use of multimedia elements, creating and editing the lectures, exercises and course assignments.
