Included server management

Every included VPS ships with YSK Server

Each US dedicated-IP VPS in a remote-dev plan is provisioned with YSK Server — YSK Limited’s own panel + CLI + API (port 9287). One host for sites, files, mail, databases, and defense; not shared hosting.

MIT-licensed single-host control plane. YSK uses it to run the machine; you can sign in to the panel too. Not a multi-tenant cloud panel.
