The Linux desktop that looks after itself.
OTT os is our own Linux desktop, built for people switching from Windows or Mac who want it to just work and to be able to undo anything.
OTT os is Omarchy. The desktop underneath is Omarchy, created by David Heinemeier Hansson and its contributors: we track its upstream releases, merge them, and add our own tools on top. Kernlux is an independent company, and is not affiliated with or endorsed by the Omarchy project.
Our app store for Omarchy.
Omarchy Store is the community app store for Omarchy Linux. Apps, themes, plugins and screensavers install in one click, and every listing is checked before it appears.
- Safe driversRefuses the ones that would break your machine.
- Restore pointsA snapshot before every change, so anything can be undone.
- Script guardExplains a script in plain language before it runs.

Yours to keep
No tracking, no accounts you do not need, your data stays on your computer.
Open to inspection
We explain how we work in public, and we credit the people whose work we build on.
Quick answers.
The basics, in plain words. The rest is on the FAQ page, or just ask.
What is Kernlux Development Labs?
Kernlux Development Labs is a software company that designs and builds desktop software for Linux: a dock, a browser, an uninstaller, a backup tool and our own operating system, OTT os. Every product is engineered, tested and checked before it ships.
Are your apps free?
The apps on this site are free to use. Each app page shows its licence, and we will say clearly on the page if anything ever changes.
What is OTT os and can I download it?
OTT os is our own Linux desktop that looks after itself: it finds safe drivers, takes a restore point before every change, explains scripts before they run and heals common problems. It is in testing and is not available to download yet. See the OTT os page.
Do your apps work with Omarchy?
Yes. Our apps are built for Omarchy and other Arch-based Linux desktops, and OTT os itself is built on Omarchy. Kernlux Development Labs is an independent company. We credit the projects we build on on our credits page.
How do you check that software is safe?
We check the licence, make sure the project is real and maintained, read our own install and setup scripts line by line, test on real machines and re-check before every release. The full list is on How we verify. When in doubt, we leave it out.
