+Zhixi is a free mind mapping product that supports multi end synchronization. The UI design is beautiful and the features are complete, but it is not open source, so it can only be used as a user and cannot be used in your project.
+
+There are many other online mind mapping products similar to Zhixi, such as [GitMind](https://gitmind.cn/)、[MindLine](http://www.mindline.cn/)、[MinMeister](https://www.mindmeister.com/zh)、[Mubu](https://mubu.com/) and so on, There are many searches on search engines, but these products either require fees or are developed by small companies, and their stability and sustainability cannot be guaranteed. Of course, the most crucial thing is that they are not open-source.

+`kityminder-core` is an open source brain mapping tool developed by Baidu. It has powerful functions and good performance, but it is no longer maintained. Therefore, the code is relatively old, and the interface beauty is relatively ordinary. In addition, bugs can only be fixed by yourself, and the functions can only be developed by yourself. It has high requirements for front-end development capabilities.

+These open-source mind maps are also good, each with its own characteristics, but they also have certain drawbacks, such as stopping updates, average interface aesthetics, less functionality, relying on a certain framework, and so on.
+
+In summary, in open-source mind maps, it is difficult to find a better choice than `simple-mind-map`. Of course, `simple-mind-map` is far from being the best, and it also has many shortcomings, as you saw in the previous [special note]. However, `simple-mind-map` has always been in a fast iteration process, and we welcome you to join and improve it together.
