What is WHM?
WHM in plain English — the definition, the analogy, and why it matters to anyone who runs a website.
The short answer
WHM is the administrative layer above cPanel — the interface where resellers and server owners create accounts, set plans and manage the platform.
Below: the fuller explanation, an analogy that makes it stick, why it matters in practice, and where you'll actually meet it.

To read, obviously
Each cPanel account manages one customer's world; WHM manages the accounts themselves — creation, suspension, quotas, packages, and server-wide settings like nameservers and security policy.
The split is the reseller business model in software form: WHM for you, cPanel for each of your customers, cleanly separated.
The analogy version
The building manager's office above the apartments — tenants (cPanel users) control their own flats; the manager allocates units, sets rules and holds the master keys.
Analogies simplify, of course — but this one holds up well enough to reason with, and reasoning is the point of a glossary.
Why you should care
If you sell or manage hosting for others, WHM is your workplace — plan design, account isolation and per-client control all live there, and its per-account licensing is the line item that shapes reseller margins.
You don't need to operate this layer daily — you need to recognise it when it's the explanation for something, which is exactly when this page pays for itself.
What it looks like in practice
A reseller creates a 'Starter' package (10 GB, 5 mailboxes) in WHM once, then provisions each new client into it in thirty seconds — isolation and limits applied automatically.
Multiply that example across every site on the internet and you have the concept's entire job description.
The HostingAlly angle
You'll meet it in the control panel and occasionally in a support conversation — usually already configured the right way. If this term made sense, the natural next reads are cPanel, Reseller Hosting, WHMCS and Control Panel.
NVMe storage and LiteSpeed caching are standard here, not premium-tier extras.
Why we wrote a hundred definitions
Every confusing term in hosting eventually becomes a support ticket — so we defined the hundred most common ones properly, once, in the plain English we'd use on the phone.
Support is answered by real people around the clock — including the questions other hosts call out of scope.

FAQ
Your questions, answered
Do regular hosting customers ever see WHM?
No — a standard hosting account is cPanel-only. WHM appears when you buy reseller hosting or your own server; it's the difference between renting a flat and managing the building.
How do WHM and WHMCS relate?
WHM provisions and controls hosting accounts; WHMCS automates the business around them — orders, invoices, suspensions for non-payment. WHMCS instructs WHM through its API; together they're the automated hosting company.
Will you move my existing website for free?
Yes — open a ticket with your current host's access details and we handle the whole move: files, databases, email and configuration, verified by you before DNS switches. The old site keeps serving until the new copy takes over, so visitors never see a gap.
Is SSL really included at no cost?
On every plan, with no exceptions — certificates are issued automatically when your domain points to us and renew themselves before expiry. The encryption is identical to paid DV certificates; paid tiers exist only for wildcard convenience or organisation-level validation.
Do you support staging sites?
Yes — plans with staging let you clone the live site, test changes safely, and push to production when ready. It's the difference between 'I hope this update works' and knowing it does.
Are backups included, and can I restore them myself?
Daily automatic backups are standard, restorable from the panel in minutes — files, databases or both, at 3am without a ticket if that's when you need it. For extra cover, you're welcome to run your own offsite copies alongside.
Do you monitor uptime, and what do you commit to?
We commit to 99.9% uptime and monitor continuously — not a marketing number but an operational one, with alerting that usually has us fixing issues before customers notice them.
