There are currently two e-Learning platforms: free or open-source and commercial platforms, which offer various payment possibilities.
Open-Source E-Learning Platforms
They are a type of software designed to be freely distributed and developed. Your license is in the public domain. Although they are used and distributed freely, it may be necessary to invest something to maintain or hire qualified personnel for their installation or updating.
This is the case of Moodle, the open-source online training platform, which today has the most reputable and is the most used by universities, training centers, and companies, preferred for its simple interface.
Chamilo, Canvas, Sakai, or the LMS for WordPress, are some other free or open-source platforms like www.allegromediadesign.com . In the case of Chamilo, although it seems more challenging to install than Moodle, it does not have as extensive a network of users as Moodle, and there are not as many references and experiences about its learning platform in forums and communities.
As for Canvas, what sets it apart from other open-source platforms is that it works entirely in the cloud and does not need to be hosted on any server. Sakai, meanwhile, has a system that is not as easy to use as Moodle, for example but adds tools for content development in a learning and interaction environment. And for those who use WordPress, it is possible to install a plugin that transforms the web into a platform for learning; some of them are LearnDash, Good LMS, Learn Press, among others similar.
Online Commercial Platforms
These do not have the free code, so you have to pay for the user license. They include two modalities according to the payment possibilities:
Pay-as-you-go e-learning platforms in the cloud. It is one of the most used alternatives lately. The subscriber pays based on the use that he will give the platform, the number of active users, courses, or modules. Pay-per-license e-learning platforms
In this case, the subscriber pays for the use of the platform for a specified time. During that time, you can use the platform for an unlimited number of users, courses, and modules. Some of the available payment platforms are eDucativa, FirstClass, Saba, NEO LMS, and Blackboard.
In education, the platform is simple and is a relatively accessible commercial LMS alternative to others. For its part, Saba Learning Suite, by its full name, also offers a complete platform to monitor learning mainly.
FirstClass is designed for more professional use due to its cost, but it is used in the cloud and adapts to all devices. At the same time, NEO LMS is straightforward to use, does not require installation, and even elementary school students can handle it. Requires programming knowledge.
Finally, Blackboard is currently one of the best-known and most used payment platforms because it allows a good user experience, although Moodle is still easier to use and also the plus of being free.
