Hello,

There is so many free Cpanel alternatives most of them has some restrictions like: Phpmyadmin, MySql, File manager but if you want to host a WP (WordPress) website than you can use them for free:

1. ZesleCP
2. VestaCP
3. Webmin
4. Ajenti

Also you can get premium versions of them as well.

As you said low-cost alternate than I would like to suggest “plesk” it is the best alternative of Cpanel.

Thanks!
