Getting started
KLYRN is a hosting control panel for Ubuntu 24.04 servers: one command installs it, and every site it hosts runs as its own Unix user with automatic HTTPS. There are three ways people start, and this page sends you to the right one.
What you are installing
One static binary that becomes two processes: a root core that owns nginx, PHP-FPM, MariaDB, the firewall and the panel database, and an unprivileged web tier that serves the panel and the API. The core never listens on the network; the web tier can never become root. The security model is the whole architecture.
- Hosts
- PHP sites, WordPress, static sites, Node.js applications, and reverse-proxied services, each in a hosting account that is a Unix user of its own.
- Does automatically
- Let's Encrypt certificates and their renewal, verified backups, a health engine with bounded self-repair, signed updates with rollback.
- Does not do
- Mail hosting, authoritative DNS, phpMyAdmin, arm64. Each is a decision with a reason, and none is on a roadmap page.
- Costs
- Nothing today. An install with no licence key runs the Free edition: one server, five sites, everything except reseller accounts. The paid editions are not on sale yet.
Three ways to start
- A fresh serverA VPS and an SSH login to a site on HTTPS with a backup schedule. Eight steps, fifteen minutes of hands-on time.
- Sites that exist somewhere elseA cPanel or DirectAdmin backup, or any server over SSH. Analysed, copied, previewed and verified before DNS moves.
- Customers to hostAccounts, limits, resellers, backups per site, suspension and deletion, and moving customers in.
KLYRN is in beta. It is tested on real servers and it is not finished. Use a fresh or non-critical server, expect updates often, and keep your own copy of anything irreplaceable. What that means, in full.
When something is wrong
Two commands answer most of it, and both work when the panel does not.
