A CyberPanel alternative on nginx and Ubuntu 24.04
CyberPanel is free and open source. Where KLYRN differs: nginx instead of OpenLiteSpeed, Ubuntu 24.04, migration with a preview, one price per server.
Start with price
CyberPanel's core is free under GPL-3.0, and its paid add-ons start at $59 a year. KLYRN is not open source. Its Free edition covers one server and five sites, and Pro is $9 per server a month. On price alone, CyberPanel wins.
These figures come from each vendor's own pages, read on 6 September 2026 and linked on our comparison page. Check them again on the day you decide.
The web server
CyberPanel runs OpenLiteSpeed, with LiteSpeed Enterprise as a paid option. LiteSpeed reads .htaccess.
KLYRN runs nginx only, tuned from the server's hardware, with one PHP-FPM pool per site under its own Unix user. nginx does not read .htaccess. KLYRN translates the rules it understands and lists the rest for you to review.
Operating system and port
CyberPanel's install page lists Ubuntu up to 22.04, AlmaLinux and CloudLinux, and the panel listens on port 8090. KLYRN runs on Ubuntu 24.04 LTS only, on x86_64, and serves its panel on port 7443.
Moving sites in
KLYRN reads the old server over SSH, copies each site and its databases while it keeps serving, and lets you open the copy before DNS moves. A final sync sends only what changed. Plain SSH migration works on the Free edition.
The old server is only read. Nothing on it is deleted or suspended, so the way back is a DNS change.
What runs as root
KLYRN is two processes from one binary. The web tier runs as an unprivileged user. The root core listens on a Unix socket only and accepts a closed list of typed operations. Releases are signed, and an update that fails its checks rolls itself back. The security page has the detail.
When to stay on CyberPanel
Stay if you need open source, LiteSpeed, or a RHEL-family system. Try KLYRN if you want nginx on Ubuntu 24.04, a migration you can preview, and one price per server however many sites it holds.
KLYRN is a young product. Read the known issues and take a backup before moving anything live.
