Get hosting. Or license what it runs on.
Websites, email and servers from £3.99 a month — or the billing, control plane and operations software underneath, licensed to run on your own machines.
Hosting for your business
One login for your websites, email, DNS and databases — not four suppliers and four renewal dates.
- One-click WordPress, Ghost and five more
- Mailboxes on your own domain
- Free SSL, renewed for you
- Daily backups you restore yourself
Software for hosting companies
Billing, a control plane and operations tooling. Self-hosted on your own servers, licensed per install.
- Zephyr — billing and provisioning
- kstack — the panel your customers use
- Standby — on-call and a status page
- Imports from WHMCS and HostBill
What you can run
Six things, one control panel.
Buy them together or on their own. One login, one bill, one place to fix things.
The software
Three products, sold separately.
They run on their own and are licensed on their own. Built to the same contract, so a licence issued in one is honoured by the others and an install updates from a single signed pipeline.

How an install stays current
No licence, no bytes.
Updates are not a download link and a changelog. A licence gates the release, the artifact is signed at build time, and the installer verifies it before anything is swapped in.
Bound to your install
A key is issued for your install and the hostnames it may run on, with rotation, revocation and an audit trail.
Signed at build
Every release is built from a tag and signed with Ed25519 — including historical ones.
Verified before the swap
Checksum, then signature against a pinned key. Anything unverified is refused.
Expiry is not a kill switch
The software keeps running and your customers keep being served. You stop receiving updates, and the admin says so plainly.
Questions
Asked most often.
Are you a hosting company or a software company?
Both, and deliberately. We run hosting on the same platform we license to other hosting companies — which means the software is exercised daily by people who have to answer the support ticket when it is wrong.
Do I have to take all three products?
No. They are licensed separately and each runs on its own. If you do run more than one they exchange licences, inventory and cost events instead of each keeping a half-right copy.
Is the software self-hosted?
Yes. Your servers, your PostgreSQL, your customer data — none of which leaves your machines. The only thing that talks to us is the update check.
Can I migrate from WHMCS or HostBill?
Zephyr imports clients, hosting accounts, domains and invoices from both. Dry-run by default and idempotent, so you can rehearse it until the numbers match. Passwords cannot be carried across.
I just want a website hosted. Is this overkill?
No — that is the other half. Hosting starts at £3.99 a month with email, SSL and backups in the price, and you never have to think about the software underneath it.
