What is better: buy a panel for hosting or write it yourself?

Question

Network administration

Hello.
I'm doing my hosting here and I want to know:
Is it better to buy a ready-made control panel (for example, ISPmanager and ISPbiling or whatever) or write your own? I know HTML and other languages ​​that can be used on the web.

Answer 1

1. brainycp - proprietary
+ script installation
+ sooo great features, the biggest I've ever seen in admin panels, and most importantly everything works
+ innovations come through updates
+ proprietary BUT free
- well, very strange interface
2. ispconfig3
+ Excellent user-friendly interface
+ Can do much more than the most complete ispmanager
+ open license
+ free
+ I personally use it on my servers
- Everything is installed by handles, the installation script is only for the panel itself, everything else is handled by handles
For example, you need to twist nginx + apache yourself, but it works fine for me.
+ If you want to write, join the community
3. bitrix vm
+ Proprietary open source
+ Free
+ cluster in a box
+ constantly updated by the market leader.
+ Has its own API, you can simply do all the settings with commands!
+ Optimized for performance and very good
+ Installation in a minute
- Console navigation, console menu but it is there.

Answer 3

Buy. You will write it yourself for more than one month. And you can't write to the commercial level.
I myself am writing now, only because there is nothing ready.
