Top free panels for VPS

New free panels, give a try.

Zeslecp.com
Ovipanel.in
TinyCP.com (I'm incredulous about this Panel, they use low RAM and CPU, very lighter panel)

Remember, free panels are risky since if they don't receive regular updates, they can be exposed to vulnerabilities. Use only for short time.

A paid panel is a good solution, they have constant updates in this case I should go with ISPManager or DirectAdmin (DirectAdmin is replacing CPanel in many Hostings like BuyVM).

Cyberpanel is great but only one domain free.

Agree, we have customers using CyberPanel, although again we prefer Webuzo Panel for single users , no restrictions ,$3/mo is the license cost (they have free version which is with limitations of scripts and php versions).
