If you're deciding on Plesk vs. ServerPilot, here are some things worth considering.
ServerPilot is the best hosting control panel for developers and businesses running their PHP applications on cloud servers.
ServerPilot prioritizes
Plesk is for hosting companies selling shared hosting as their primary business. It is also sometimes used by developers who are hosting client websites on VPSes when Plesk comes with their VPS.
Plesk prioritizes
If security is critical to you, you should use ServerPilot. Plesk users have suffered multiple critical exploited security vulnerabilities in recent years.
If already have mail hosted using Plesk, you can continue to use Plesk just for email hosting and move your apps to servers managed by ServerPilot for ServerPilot's better web hosting configuration. Alternatively, if you don't have mail hosted in Plesk already, there are other options for hosting mail.
