is dedecms free?

DEDE, PHPCMS and Empire are all licensed models, that is, personal non-commercial use is free, but websites generally have small advertisements or something, even if they are commercial, but generally the website is small. No one is looking for you. Currently, the only truly free and open source one in China is JTBC CMS. You might as well give it a try to see if it’s suitable for you. Each CMS is suitable for different people. There are several programs, which one is better and which one is worse? Choose according to preference.

1. Mainly based on official templates, from the aesthetic point of view
The aesthetics of phpcms release is better in Wuyou Host. The interface is simple and elegant. dedecms has always used a green template, which has not changed much. The Empire is more ugly, and you have to modify the default template yourself before the homepage can display the required data. It is not as convenient as dede and phpsms, which will automatically call the template. This is a bit difficult for novices.
2. In terms of program running speed
The operation generation speed of Empire should be the fastest. It may be due to the architecture. The speed of phpcms is not too slow, almost the same as Empire. As for dede, it is a bit mediocre. Both the background operation and the homepage access speed are not ideal. The current 5.7 speed, especially the homepage access speed, is good. The previous version was very laggy. This is the flaw that DreamWeaver has always had.
3. From the perspective of security
Empire’s security is very good. Empire’s slogan is “the most secure cms”. Empire basically has no updates on security vulnerabilities. Updates are basically version updates.
The security of phpcms is also pretty good, there are no loopholes. DreamWeaver is notoriously riddled with holes and has been updated a lot, so its security performance needs to be further improved. For this reason, some foreign space providers prohibit users from using the DreamWeaver program.
4. In terms of functions
Because they are all cms programs, the functions of dede, empire, and phpcms can meet everyone's needs.
5. Judging from the user experience after installation,
Empire’s website building tutorial is still very smooth. For example, it is relatively simple to modify the template, add content, etc. The official help document is very complete and I have basically never encountered it. Faults in program execution. Dede is also very easy to use, and all functions are clear at a glance. This may be because the program updates quickly, and there are few program failures. Finally, there is the difficult phpcms. The official help of phpcms is not perfect, and we often encounter various problems during use, but as long as we do not make any modifications to the program, it is still good to use.
6. In terms of the number of bugs and bugs
Based on the sebug data, both DreamWeaver and phpcms have a lot of bugs. There are so many every year that they take up a full screen. It is best to The Empire has only had a few holes over the years.
7. From the perspective of official services and support
For free users, in fact, the services of the three companies are relatively "not caring". The editor thinks that phpcms is the worst among them. There is rarely a response even if I post a post. Therefore, there is still a lot of research on phpcms. There are many enthusiastic netizens who will reply to the forums of the Empire, and the official tutorials are also relatively complete. Dreamweaver is the best, which is one of the reasons why most users like to use dede.
8. In terms of program version updates
Dreamweaver's version update is undoubtedly the fastest, and it is normal to update it two or three times a year. Relatively speaking, the update speed of the Empire is very slow. It is calculated on an annual basis. There may be no update once in a year. Of course, this is based on the relatively complete foundation of the Empire itself. There are no loopholes and functions. It’s powerful and there’s no need to update it so frequently. The update of phpcms is generally slow and normal.
