Hello, I'm glad to answer your question! Anyone familiar with software development knows that educational source code is the result of hard work of technicians, and there will be no free source code. Even if there is, there are still many disadvantages except some gimmicks. For example:

1. In the process of live broadcast, jams and flashbacks often occur.

Although there are unstable factors in the live broadcast process, the picture is delayed, but the educational source code, as the basis for realizing all functions, has a poor foundation and problems are inevitable in the later stage.

2. During the live broadcast, there is a problem with the voice and video connection.

If the user experience is not well satisfied, the development of online education platform will not last long. Therefore, in order not to affect the user experience, it is a very big thing to have problems such as voice and video connection during the live broadcast.

3, free online education source code, security can not be guaranteed.

4. The source code of free online education does not support post-maintenance, and problems in the later stage need to be solved by professional and technical personnel.

......

In a word, if you want to develop steadily in the education industry, you should not have the idea of finding a source code from the Internet casually, or there will be various problems later.

Above, I hope I can help you, hope to adopt ~
