# Multi Server Edition

Welcome to the PanelAlpha Multi Server Edition documentation.

Multi Server Edition is designed for companies that run WordPress hosting across multiple servers and external services. It combines a client-facing interface (Client Area) with centralized administrator tooling (Admin Area) so you can manage provisioning, operations, and platform-wide configuration from one place.

Use it to connect hosting servers, automate onboarding, manage migrations, configure plans, and integrate DNS, email, billing, SSL, analytics, and other supporting services across your infrastructure.
