Let’s remember that an operating system (OS) is the main software on a computer or mobile device that manages all other software and hardware, like Windows on desktop or Android on mobile. It lets you run apps, organize files, and interact with the device, acting like a bridge between you and the machine to make everything work smoothly.
We’re mostly used to a limited set of options when selecting an OS for our devices, and it’s not uncommon to just keep the one that came first with the device itself. However, it’s possible to change it for another one, in most cases. And that other one could bring more benefits and features —like being lighter or more private.
Of course, there are also free and open-source OS available for everyone, and we’re going to list some of them ahead. If you find them handy, you can always donate to them in cryptocurrency via

This system is also widely recognized for contributing to the OpenSSH software, used for secure remote communications worldwide.
OpenBSD’s main features include its robust cryptographic integrations, a meticulously crafted firewall, and continuous code auditing to maintain high security. It’s particularly popular for secure applications such as firewalls, routers, and intrusion detection systems. OpenBSD has also refined techniques like privilege separation, which restricts applications' access to certain system resources, bolstering its secure-by-default reputation.
Funding for OpenBSD comes from donations and support from the OpenBSD Foundation, a Canadian non-profit formed in 2007 to provide sustainable backing. If you’re interested in donating crypto to this project, you can find them on Kivach as
LineageOS is a free OS for mobile devices like smartphones and tablets, initially launched in December 2016, as a fork from the discontinued CyanogenMod.

Ubuntu Touch is a free operating system tailored for mobile devices, developed by the UBports community. Originally launched by the firm Canonical in 2013, it was later passed to UBports in 2017 after Canonical discontinued support. Primarily designed for smartphones and tablets, Ubuntu Touch is unique for its "convergence" feature, which aims to extend the mobile experience to desktops and TVs.
While its primary focus remains mobile, it also offers an innovative experience by transforming a phone into a desktop when connected to a monitor.
Another standout feature of
The community releases periodic updates, keeping the OS adaptable and secure. In recent years, support has been extended to newer devices like the PinePhone, providing users with an alternative to Android and iOS backed by a committed open-source community.

Built on Xubuntu but shifting towards Debian in recent versions, Kodachi offers a user-friendly platform that requires no special Linux expertise to benefit from its privacy features. It comes with preconfigured tools for secure browsing and communication, including VPN, Tor network integration, DNSCrypt, and cryptographic utilities for file encryption and secure messaging. Its anti-forensic capabilities prevent data recovery attempts, while network monitoring tools provide real-time insights into security status.
Kodachi’s design ensures that online activities remain anonymous, making it particularly useful for high-stakes privacy needs. Maintained as a one-person project by Al Maawali, Kodachi sustains itself through community donations, including options for cryptocurrency and PayPal support. If you find it useful, you can
Developed by Patrick Schleizer and released in 2012,
It operates through a unique setup involving two isolated virtual machines (VMs): Whonix-Gateway, which routes all traffic through Tor, and Whonix-Workstation, where users can safely perform tasks. Therefore, it's used as a "guest" OS that relies on a "host" OS (such as Windows or Linux) to provide the virtual environment in which it operates. Unique features include
Funding for Whonix primarily comes from user donations, paid support services, and grants. The project has evolved through multiple updates, enhancing its compatibility and strengthening its privacy protections, while maintaining a focus on open-source principles and community engagement.
