From Singapore: In an era when the cost of enterprise software subscriptions is rising and data sovereignty concerns are becoming a boardroom issue across the Indo-Pacific, a small open-source project from Turkey is quietly building something worth watching. NebiOS, a Linux distribution developed under the NebiSoft umbrella by a solo developer named Sarp Mateson, has attracted genuine attention in the Linux community for its ambition: a complete, privacy-respecting alternative to Google Workspace, packaged into a single operating system.
For Australian businesses that have grown uneasy about the concentration of their productivity data inside a handful of American cloud giants, that pitch has obvious appeal. The question is whether NebiOS is ready to deliver on it.
What NebiOS Actually Offers
NebiOS is a Linux distribution from Turkey that has been in development since 2023. It is the work of Sarp Mateson, building the Ubuntu-based distribution under the NebiSoft umbrella, beginning it as a personal project that has since evolved into a complete operating system with an entire ecosystem surrounding it. Born as a personal project over a decade ago, when it was known as "Spez Linux", today's Ubuntu-based NebiOS has grown into a full-fledged operating system with an entire ecosystem that accompanies it.
What makes it stand out is the NebiDE desktop environment, a Wayfire-based custom Wayland compositor. Other highlights include Steam Proton integration, easy multi-kernel installation via an integrated kernel switcher, the NebiOS App Runtime portable app with bubblewrap containerisation, and more. Reviewers have compared the overall aesthetic to a blend of KDE Plasma and GNOME, with well-executed animations and a clean panel layout. The overall interface feels familiar, with Windows 7 Aero-like elements mixed in, and there are pre-configured widgets including a music player, clock, RSS reader, and sticky notes.
NebiOS has no telemetry, no background data services, no tracking daemons, and cannot send any personal data without user action — a meaningful differentiator for any organisation cautious about where its information flows.
The Google Workspace comparison is anchored by NebiCloud, a companion cloud service that uses Nextcloud as its interface. NebiCloud provides a suite covering files, calendar, photos, activity tracking, contacts, mobile tracking, notes, music, announcements, forms, TV events, tasks, podcasts, and a password manager. NebiCloud offers a free account providing 10GB of file storage.
The Security Problem That Cannot Be Ignored
Here is where the enthusiasm needs to be tempered. Reviewers found it difficult to locate information about NebiCloud, including pricing details or confirmation of active development. NebiCloud is open source, and the most recent activity on its GitLab repository dated from 2024. That is a significant problem for a cloud service handling sensitive personal and business data.
Given that NebiCloud has not been in active development for some time, there are likely security vulnerabilities present, and connecting NebiOS to the service is not recommended. This concern is not abstract. The broader Nextcloud ecosystem, on which NebiCloud is built, has a well-documented vulnerability history: in 2024 alone, Nextcloud had 16 security vulnerabilities published. An unmaintained fork of Nextcloud would carry those risks without the benefit of the patches that Nextcloud's active development team routinely issues.
For Australian businesses that might otherwise see NebiCloud as a locally-controllable alternative to Google Drive or Microsoft 365, this is not a minor footnote. Data breach obligations under the Notifiable Data Breaches scheme administered by the Office of the Australian Information Commissioner mean that deploying cloud software with known, unpatched vulnerabilities carries real legal and reputational risk.
The OS Itself Remains Actively Developed
It would be unfair to conflate the stalled NebiCloud with the state of NebiOS itself. The operating system is a different matter. Version 10.2, released in late February 2026, focuses on a completely rewritten napp-runtime and Bundle Store, the component that manages apps, packages, and services for users to install. Although still experimental, NebiOS 10.2 is also the first release to include a separate ISO for systems with Nvidia GPUs; the ISO bundles the 590 driver, though users should note it lacks support for Pascal-based cards such as the GTX 1080 Ti or GTX 1050 Ti.
With NebiOS X, the X11-based NebiDE Legacy era has officially come to an end. That environment was only available in NebiOS 2 and 3; from now on, the Wayland-based modern NebiDE is the default, forming the foundation for all future releases. That is a consequential architectural commitment. Wayland is the modern display protocol that the broader Linux world is converging on, and building NebiDE from the ground up for it positions the project well for the long term.
The installation experience is also genuinely accessible. NebiOS uses the Calamares installer for system installation, which offers a clean and straightforward setup process with standard options including disk partitioning, user account creation, and timezone selection. The Calamares installer works well on NebiOS. That matters if the distro is ever to reach beyond its current enthusiast audience.
A Signal Worth Tracking
The broader trend NebiOS represents is one Australian policymakers and technology buyers should pay attention to. Across the Indo-Pacific, interest in reducing dependence on a small number of dominant American cloud platforms is growing. Whether the motivation is data sovereignty, cost control, or privacy compliance, the demand for credible open-source alternatives is real. Australia's Digital Transformation Agency has been gradually updating its guidance on cloud procurement, and open-source productivity software is increasingly part of that conversation.
NebiOS, at this stage of its development, is not an enterprise-ready replacement for Google Workspace. It is a compelling proof of concept with genuine design quality and a clear philosophical direction. The NebiCloud problem is solvable: either through renewed development effort from the NebiSoft team, or by users pointing the OS at a self-hosted, fully maintained Nextcloud instance instead. That flexibility is, arguably, the whole point of open-source software.
For Australian businesses willing to run their own infrastructure, the OS itself is worth trialling. For those who need a managed cloud service to come with it, the wait continues. Reasonable people in IT procurement can look at the same set of facts here and reach different conclusions about acceptable risk. That is exactly the kind of honest trade-off that open-source software forces its users to confront, which is not a weakness but a feature of the model.
