Getting started
KLYRN is a hosting control panel for Ubuntu 24.04 servers. One command installs it. Every site it hosts runs as its own Unix user with automatic HTTPS.
What you are installing
One static binary runs as two processes. A root core owns nginx, PHP-FPM, MariaDB, the firewall and the panel database. An unprivileged web tier serves the panel and the API. The core never listens on the network, and the web tier can never become root. See the security model.
- 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
- arm64,
.htaccessat runtime, filesystem quotas. Each limitation, with its reason. - Costs
- Nothing today. An install with no licence key runs the Free edition: one server, five sites, everything except cPanel and DirectAdmin migration, staging and resellers. Pro adds unlimited sites, migration and staging for $9 a month per server.
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.
- 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, suspension, and moving customers in.
KLYRN is a young product. Take a backup before you move a live site onto it, and keep your own copy of anything irreplaceable. What that means, in full.
When something is wrong
Both commands work when the panel does not.
