The 11 tools, reviewed
#1 Zorin OS
Linux desktop built for people leaving Windows · Ireland · zorin.com
Windows switchers Free Core edition Familiar layouts
Zorin earns the top place by lowering the cost of the first experiment. The company's site says the Core edition is free, that you can test-drive from a USB stick with no installation, and that a computer up to about fifteen years old should run it. Pro adds layouts resembling macOS, Windows 11 and ChromeOS, plus bundled professional applications, for a one-time payment tied to a major version.
- Pricing: One-time purchase / major version. Core edition is free to download; Zorin OS Pro is a one-time payment per major version, with the price shown at checkout rather than on the product page. Free plan: free plan.
- Best for: Offices moving laptops off Windows
- Strengths: Windows-like desktop layouts; Run from USB before installing; Core edition free.
Where it falls short
There is no published enterprise support contract that we could find, and Zorin Grid, its tool for managing a fleet, is shown as coming soon. Pro must be repurchased for each major version. The registered company number differs between two of its own legal pages.
Wrong for
A company that needs a vendor contract, remote fleet management or certified hardware today should look at SUSE, Red Hat or Ubuntu Pro instead.

#2 SUSE Linux Enterprise Desktop
Supported enterprise Linux desktop from a European vendor · Luxembourg · suse.com
Enterprise desktop European vendor Subscription support
SUSE sells the desktop as a product with a support organization behind it: its site advertises transparent, follow-the-sun, personalized service, long-term service support and training. The company's contact page names SUSE S.A. as headquarters and registered office in Luxembourg, with a large German presence in Nuremberg, which matters to buyers with European jurisdiction requirements.
- Pricing: Quote only. Sold as a support subscription; the product page points to subscription options and does not list a price. Free plan: none.
- Best for: Companies that need a support contract
- Strengths: SUSE Linux Enterprise Desktop; Support subscription plans; Follow-the-sun support.
Where it falls short
Pricing is hidden, a free trial was not stated on the pages we read, and the desktop edition has a far smaller community than Ubuntu or Debian. Hardware certification and application availability need checking per model. Small companies may pay for support they never use.
Wrong for
A small office without a support requirement is better served by Zorin OS or Ubuntu, and a team that wants published prices should consider Ubuntu Pro.

#3 iodéOS
Google-free Android with a built-in tracker blocker · France · iode.tech
LineageOS base Built-in blocker French company
iodéOS describes itself as an Android operating system freed from Google trackers, powered by LineageOS and crediting the microG project. Its standout feature is a built-in blocker that runs permanently on the device and, as the company explains, works locally without collecting what happens on the phone.
- Pricing: Open source + paid tiers. The OS is free; the company's income comes from smartphone sales, premium subscriptions and donations. Free plan: open source.
- Best for: Teams wanting tracker blocking on Android
- Strengths: Android operating system without Google trackers; LineageOS and microG base; Built-in iodé blocker.
Where it falls short
It depends on LineageOS for device support, so the supported list follows that project. The blocker works by intercepting connections locally, which some security teams will want to review.
Wrong for
A team that needs published business support or a hardened security model should look at GrapheneOS or a managed Android program.

#4 /e/OS
De-Googled Android with a bundled online account · France · e.foundation
De-Googled Android French nonprofit Bundled Workspace
The e Foundation describes /e/OS as an open source Android build with no Google apps or services accessing personal data, paired with selected apps and an optional Murena Workspace account. It is run by a French association registered in 2018 in Paris, with Murena Retail SAS selling phones and accessories from a separate Paris address.
- Pricing: Open source + paid tiers. The OS is free and open source. Free plan: open source.
- Best for: Teams leaving Google on phones
- Strengths: Android-based mobile OS; No Google apps or services; Murena Workspace mail and drive.
Where it falls short
The bundled workspace gives you a second account to exit later, and the MDM is still in beta, so a company fleet has little central tooling. Installation on your own handset needs an unlocked bootloader and a supported model.
Wrong for
A security-focused team that wants the strongest hardening on a short device list should look at GrapheneOS, and a firm that needs mature fleet management should stay with managed Android.

#5 GrapheneOS
Hardened Android for Google Pixel phones · Canada · grapheneos.org
Hardened Android Pixel only Nonprofit
GrapheneOS focuses on one job: a hardened mobile system for a short list of devices. Its FAQ lists Pixel models from the 8 series through the Pixel 10a, states that eighth-generation and later Pixels carry a minimum of seven years of support from launch, and offers a browser-based installer.
- Pricing: Open source. Free and open source; funded by donations, and the project sells no product or support plan. Free plan: open source.
- Best for: Security-sensitive teams using Pixels
- Strengths: Hardened Android build; Official support for Pixel 8 to Pixel 10 series; Minimum 7 years of support from launch.
Where it falls short
It runs only on Google Pixel hardware, which ties you to Google's phones even as it removes Google's software. There is no commercial support contract and no fleet management we could find documented. The bootloader must be unlocked at install.
Wrong for
A company that needs a help desk, a mix of handset brands or centralized device management should choose a managed Android setup or /e/OS.

#6 Ubuntu
General-purpose Linux with paid extended support · United Kingdom · ubuntu.com
Desktop and server LTS releases Ubuntu Pro
Canonical's site calls Ubuntu the preferred choice for professional developers, and the numbers support its default status. Release 26.04 LTS has standard security maintenance to May 2031, expanded maintenance to May 2036 and a legacy add-on to May 2041. The desktop needs a 2 GHz dual-core processor, 6 GB of memory and 25 GB of disk.
- Pricing: Open source + paid tiers. Ubuntu is free to download; Ubuntu Pro is free for personal use on up to 5 machines and sold to enterprises after a 30-day trial. Free plan: open source.
- Best for: Mixed fleets needing wide app support
- Strengths: Ubuntu Desktop LTS; Five years of free security updates; Up to 15 years with Ubuntu Pro.
Where it falls short
Enterprise prices were not visible on the pages we read, so budgeting means a quote or a calculator. The default desktop can feel unfamiliar to Windows users. Long support windows arrive only with a paid Pro subscription.
Wrong for
A team that wants Windows-like screens on day one should try Zorin OS, and a company that wants to avoid a single commercial sponsor should look at Debian.

#7 Red Hat Enterprise Linux
Enterprise Linux with a ten-year life cycle · United States · redhat.com
Enterprise Linux Ten-year life cycle IBM-owned
Red Hat's lifecycle page describes versions 8, 9 and 10 as a ten-year life cycle across three production phases, and its enterprise Linux page lists a Workstations variant aimed at graphics, animation and scientific work. The company states that it has been joined with IBM since 2019, and it publishes a Raleigh address.
- Pricing: Per system / year. Subscription-based; Red Hat also offers no-cost developer subscriptions, and prices are not shown on the product page. Free plan: free plan.
- Best for: Regulated firms and Red Hat server shops
- Strengths: Red Hat Enterprise Linux for Workstations; Ten-year life cycle; Developer subscriptions at no cost.
Where it falls short
It is built around servers and high-performance workstations, so the everyday office desktop experience is thin. Pricing is subscription-based and was not shown on the pages we read. The IBM ownership means strategic decisions sit far from the people who use the product.
Wrong for
A ten-person office, or anyone who wants a polished general desktop, should look at Zorin OS or Ubuntu, and a team that wants server parity without a license should consider AlmaLinux.

#8 Pop!_OS
Linux desktop from a Colorado computer maker · United States · system76.com
Developer desktop Full-disk encryption Hardware maker
System76 says Pop!_OS is engineered in-house at its Denver factory, is free to download and collects zero user data, with full-disk encryption where only the user holds the key. The company claims over a million users. Because System76 makes computers as well as software, drivers and firmware on its own machines are designed together, which a general distribution cannot promise.
- Pricing: Open source. Free to download; System76 sells computers that ship with it. Free plan: open source.
- Best for: Developers and creators on Linux laptops
- Strengths: Pop!_OS desktop; Full-disk encryption; Zero user data collected.
Where it falls short
Support is tied to System76 hardware, and the company is small next to the vendors above. It has no enterprise subscription or fleet tool on its public pages. Release timing depends on one company's priorities.
Wrong for
An office that wants a familiar Windows-style layout or a vendor contract should look at Zorin OS or SUSE, and a team on non-System76 laptops should test hardware first.

#9 AlmaLinux OS
Free enterprise Linux compatible with RHEL · United States · almalinux.org
RHEL compatible Foundation governed Server-first
The AlmaLinux OS Foundation describes the system as a free, community-owned and governed enterprise Linux distribution focused on long-term stability and binary compatible with RHEL, and its site lists a certification catalog and an upgrade tool called ELevate. The foundation states that it is a registered 501(c)(6) organization under US law, with an address in Estero, Florida.
- Pricing: Open source. Free and open source; the foundation runs a membership program and a shop. Free plan: open source.
- Best for: Teams matching Red Hat servers for free
- Strengths: Binary compatible with RHEL; ELevate migration tool; Community governance.
Where it falls short
The project is server-first, the desktop is not its selling point, and there is no commercial support from the foundation itself, though third parties sell it. Compatibility depends on keeping pace with Red Hat's releases. The foundation is a trade association structure, not a charity.
Wrong for
A nontechnical office should choose Zorin OS, and a company that needs a support contract from the vendor itself should choose Red Hat or SUSE.

#10 Debian
Volunteer-run universal Linux base · United States · debian.org
Volunteer project Stable releases Base for others
The Debian site calls the project an association of individuals who have made common cause to create a free operating system, and its releases page names version 13, codenamed trixie, first released in August 2025, as current stable, with a version 13.7 update in September 2026.
- Pricing: Open source. Free to download and use; there is no commercial edition or support plan from the project. Free plan: open source.
- Best for: Administrators who value stability
- Strengths: Stable release 13 (trixie); Testing and unstable branches; Free software focus.
Where it falls short
There is no company to call, no support contract and a plainer desktop experience than the products above. Debian itself is not a legal entity; the trademark holder's state is New York and its city was not verified.
Wrong for
A company without an administrator should pick a supported product such as Ubuntu or SUSE, and a team that needs polished onboarding should choose Zorin OS.

#11 Ubuntu Touch
Linux mobile OS maintained by a German foundation · Germany · ubports.com
Not Android German foundation Community
UBports describes Ubuntu Touch as an open source Linux mobile operating system built to be a daily driver, and a recent 24.04-2.0 release was announced on its site. The foundation page says the UBports Foundation is a charitable foundation under German law, with an installer, an OpenStore app catalog and a published list of supported devices.
- Pricing: Open source. Free and open source; the foundation is the foundation takes donations and runs a membership program and a shop. Free plan: open source.
- Best for: Hobbyists and pilots of non-Android phones
- Strengths: Ubuntu Touch mobile OS; Lomiri interface; OpenStore app catalog.
Where it falls short
Mainstream apps, banking tools and some hardware features often have no equivalent. Device choice is limited, and the foundation's city and address were not found on its public pages. It is a poor fit where staff need reliable messaging and authenticator apps.
Wrong for
A business that needs mainstream apps on phones should choose /e/OS or GrapheneOS, and anyone needing a support contract should stay on managed Android.

Questions and answers
What is the best operating system alternative to Windows in 2026?
Zorin OS ranks first of 11, best for offices moving laptops off Windows. SUSE Linux Enterprise Desktop is second (companies that need a support contract) and iodéOS third (teams wanting tracker blocking on Android). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
What is the best alternative to Android for company phones?
/e/OS stands out because it publishes a device selector for installation, ships with a bundled online account and is run by a French nonprofit with a commercial retail arm.
Can I run Windows applications on these Linux systems?
Some, not all. Browser-based tools run unchanged, and many Windows programs can run through compatibility layers, but anything that depends on a Windows-only driver, a macro-heavy Office file or a vendor's licensed client needs testing.
Is Linux secure enough for a business without an antivirus subscription?
Linux has a different threat profile from Windows, but security still depends on patching, disk encryption and account hygiene. A distribution with a long, supported update window matters more than a product name.
How much does it cost to replace Windows with Linux?
The licenses are free for most entries here, but the cost moves to people and testing.
What happens to my data if I switch away from a de-Googled phone system?
Contacts, calendars and files stay wherever you stored them.
Which Linux distribution suits a company that already runs Red Hat servers?
AlmaLinux is the closest free match, since the foundation describes it as binary compatible with RHEL and forever free, which suits teams that want server parity without a Red Hat subscription.
Is Debian a good choice for office desktops?
Debian suits an organization that has an administrator and values stability and a long-standing volunteer project. Its current stable release is version 13, codenamed trixie, first released in August 2025.
Can Linux be managed centrally like a Windows fleet?
Yes, but the tools depend on the product. Ubuntu Pro adds fleet management features, Red Hat sells Ansible Automation Platform alongside its enterprise Linux, and Murena lists an MDM service that it labels as beta.
Do de-Googled phones work with banking and work apps?
Many do, but it varies by app and by system, and you should test the exact applications your staff use before buying handsets.
How long will an operating system on this list keep getting security updates?
It depends on the product and the release. Red Hat Enterprise Linux publishes ten years across three phases.
