Software that looks after your Linux desktop.
We build the apps that make a Linux desktop feel finished: a dock, a browser, an app store, a safety net. Every one is built, tested and checked before it ships.
One family, built to work together.
Each app does one job well and looks like it belongs next to the others.
SnapDock
A floating glass dock with real three-dimensional icons, snap layouts that truly tile, and a clean uninstall.
Otto Browser
A Chromium browser that follows your desktop theme, keeps trackers out and blocks ads.
Omarchy Store
The app store for Omarchy: install, update and remove apps, themes, plugins and screensavers in one click.
Jettison
Every app, from every source, removed cleanly with nothing left behind. And everything can be undone.
Lifeboat
Back up, restore and clone your whole setup to your own Google Drive.
Rabbit Ears
Free live TV for your desktop: public channels, a live programme guide and favourites. No account.
otto OS: the desktop that fixes itself.
Our own take on a complete Linux desktop, built for people switching from Windows or Mac who want it to just work, and to be able to undo anything.
- Finds the right drivers, and refuses the ones that would break your computer
- Takes a restore point before every change
- Explains a script in plain language before it runs
- Tells you the moment your desktop is ready
Four promises behind every app.
Checked first
Licence, source and install scripts are read before anything is offered to you.
Easy to undo
Changes are reversible, and removing an app leaves nothing behind.
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?
We are a small software studio that builds the apps a Linux desktop is missing: a dock, a browser, an app store, an uninstaller, a backup tool and our own desktop, otto OS. Every app is built, 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 otto OS and can I download it?
otto 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 otto OS page.
Are you part of Omarchy or 37signals?
No. Kernlux Development Labs is independent and is not affiliated with or endorsed by 37signals or the Omarchy project. Omarchy is a registered trademark of 37signals LLC. 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 install scripts line by line, test it on our systems and re-check on a schedule. The full list is on How we verify. When in doubt, we leave it out.
