BlossomOS

The desktop operating system for digital independence, finally practical for everyday use.

More and more consumers and companies want to break free from dependence on big corporations. No data collection, no forced updates, no built-in ads, no AI features you can't disable. Linux would be the answer if it didn't have so many issues: conflicting package formats, installation routes through detours and terminals, systems that are unstable or just don’t look modern. And for companies, there’s also no reliable point of contact. BlossomOS solves that.

Every piece of software with one click, no compromises.

BlossomOS puts you at the center. The system adapts to your way of working, not the other way around. Modern design, and everything with one click through the Arc Software Store.

Features

Arc Software

An app store for everything you need. Search for software and install it with one click, no detours.

• Arc Unify – On Linux, there are countless ways to install software: different formats, different stores, packages from the internet. Just open the file, Arc handles the rest via Distrobox in the background.
• Arc Winapps – Even Windows apps, which usually require extra effort, go straight into the Arc Software Store.

pkglayer

If you prefer staying in the terminal, you can. Just type yay, apt, nix, or whatever you’re used to, pkglayer takes care of the rest through Distrobox in the background. No performance overhead, everything appears immediately.

Blossom Cloud

Collaboration and data backup, kept simple.

• File synchronization – Classic cloud sync, e.g. for recovery after a reinstall.
• Better together – Work together on documents via the Blossom Office Suite, video calls via Jitsi.
• Your data is safe – EU data centers, strong encryption, also suitable for highly secure institutions.
• Coming soon: Synchronization of settings – Wallpaper, installed programs, everything backed up in the cloud and restored immediately after reinstall.

Built on a stable foundation

• KDE Plasma – A mature, open desktop. Secure, stable, accountable only to its community.
• Immutable system core – BlossomOS is immutable. The core remains clean and unchangeable; thanks to Arc Unify and pkglayer, you don’t notice it.
• Completely open source – Everything is open on git.blossomos.org. Contributions welcome. State-of-the-art offline encryption and hardware-backed security features included.

Modern design that just works

• Unified appearance – KDE apps, GTK programs, everything fits into the same design.
• We developed a completely new desktop design. And if you want to personalize it, you can easily adjust colors, style, and appearance.
• Every corner of the desktop was thoughtfully designed and actively adapted.

Don't throw away your computer. BlossomOS runs cleanly even on older devices. Good for your wallet, good for the environment.

Software development as easy as never before. App platform, documentation, sample files, and developer tools included. Developer mode sets up everything you need.

Coming soon: Blossom Hub. Full control over your company data, designed for mass deployments. Create BlossomOS accounts, set up centralized login, enforce policies, manage inventory, roll out apps via the store. Compliant, secure, no own IT department needed.

Standing still is not an option.

BlossomOS is intuitive, modern, and fast, but that’s not enough for us. We ask with every feature, interaction, and detail how we can make it even better. More intuitive, more modern, faster, more stable. That’s our premise.
