Hosting Terms
What is WHM?
WHM in plain English — the meaning, the comparison, and why it matters to anybody running a website.
Straight answer first
WHM is the administrative deck above cPanel — where resellers and server owners create accounts, define packages and set the rules for the whole platform.
Below: the fuller explanation, a picture that makes it stick, why it matters in practice, and where you will actually run into it.

To read, naturally
A cPanel account runs one customer's world. WHM runs the accounts themselves: creating them, suspending them, setting quotas, building packages, and holding server-wide settings such as nameservers and security policy.
That split is the reseller business model written into software. WHM for you, a separate cPanel for each of your customers, with a clean line drawn between the two.
The everyday comparison
The manager's office behind a row of shop units. Each trader runs their own unit however they like; the manager allocates the units, sets the rules of the market and keeps the master keys in a drawer.
Comparisons simplify, naturally — but this one holds together well enough to reason with, and reasoning is the whole point of a glossary.
Why this one is worth knowing
If you sell or look after hosting for other people, WHM is where you work. Package design, account separation and per-client control all live in it, and its per-account licence cost is the line item that decides whether reseller margins work.
You do not need to work at this layer every day. You need to recognise it when it explains something, which is exactly the moment this page earns its keep.
What it looks like day to day
A reseller builds a 'Starter' package once — 10 GB, five mailboxes — then drops each new client into it in about thirty seconds, with the limits and the isolation applied automatically.
Multiply that example by every website on the internet and you have the concept's entire job description in one go.
The Hosting Seller angle
You will meet it in the control panel and occasionally in a support conversation, usually already set the right way. If this term made sense, the natural next reads are cPanel, Reseller Hosting, WHMCS and Control Panel.
NVMe disks and LiteSpeed caching sit on the shelf at every price point, not behind a premium tier.
Why we bothered with a hundred definitions
Every confusing term in hosting turns into a support ticket sooner or later, so we defined the hundred most common ones properly, once, in the plain English we would use across the counter.
Real people answer the counter at any hour, including the awkward questions other hosts wave off as out of scope.

Pictures that stick
Each concept gets a comparison you will still remember at the moment you actually need it.
First Steps
From choosing to live
- 1
Find it in your own account
Open the control panel and find where this concept lives — seeing it attached to your own site is what turns a definition into understanding.
- 2
Check what the defaults are
Our platform ships sensible defaults for this — check rather than assume, and you will know your setup instead of hoping about it.

Across the Counter
The questions we get asked most
Do ordinary hosting customers ever see WHM?
No. A standard hosting account gives you cPanel and nothing above it. WHM appears once you buy reseller hosting or a server of your own — it is the difference between renting a unit and managing the parade of shops.
How do WHM and WHMCS fit together?
WHM creates and controls the hosting accounts; WHMCS runs the business wrapped around them — orders, invoices, suspensions when nobody pays. WHMCS gives WHM its instructions over an API, and together the pair make an automated hosting company.
Do you shift an existing site across at no charge?
We do. Open a ticket with the login details for your current host and the whole lot comes over: files, databases, mailboxes and configuration. You check the copy before DNS changes hands, and the old site keeps serving customers until the new one takes the traffic, so nobody ever sees a gap.
Is the SSL certificate genuinely free?
On every plan, with nothing held back. The certificate is issued the moment your domain points here and reissues itself well before expiry. The encryption is the same as a paid DV certificate — paid tiers exist only for wildcard coverage or organisation validation, which most sites never need.
Can I test changes somewhere safe first?
Yes — plans with staging let you clone the live site, work on the copy, then push it across when you are satisfied. It is the difference between hoping an update behaves and knowing that it does before any customer meets it.
Are backups included, and can I put one back myself?
A backup is taken daily on every plan, and the restore is yours to run from the panel in minutes — files, databases or both, at three in the morning without waiting on a ticket. Keeping your own copy offsite as well is never a bad habit, and nothing here stops you.
What uptime do you commit to, and who is watching?
We commit to 99.9% uptime and watch it continuously. That figure is an operational target rather than a poster line, and the alerting behind it usually has an engineer on a problem before the first customer notices anything is wrong.
