Software for running a hosting business.
Zephyr sells and bills, kstack runs the hosting, and Standby proves your compliance and watches every server. Each is licensed on its own and runs on your own machines.
From £9 a node, a month
Each product is licensed on its own.
Three products, sold separately.
They run on their own and are licensed on their own, and they work together when you use more than one.
Commerce. Website, shop, billing and support, and provisioning for hosting companies. A paid invoice becomes a working account; a missed one suspends it. Coming soon.
Hosting panel. Websites, mail, DNS and databases for your customers, on servers you own. £9 a node, a month, from ten nodes.
Compliance and operations. Audit evidence for 24 frameworks, a public Trust Center, on-call paging and security. Coming soon.
Frequently asked questions
Do I have to take all three products?
No. They are licensed separately and each runs on its own. If you run more than one, they work together without extra setup.
Is the software self-hosted?
Yes. Your servers and your customer data, none of which leaves your machines. The only things that talk to us are the licence check and 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 running it twice never creates anything twice, so you can rehearse it until the numbers match. Passwords cannot be carried across.
When can I buy Zephyr and Standby?
They are coming soon. kstack is on sale now. Register your interest on the Zephyr and Standby pages and we will email you when each one launches.
Can I see it working before I buy?
Yes. Tell us what you run today and we will walk you through it on a call.
