Chromium OS
Google
Chromium OS is an open-source project that aims to build an operating system that provides a fast, simple, and more secure computing experience for people who spend most of their time on the web. Here you can review the project's design docs, obtain the source code, and contribute. We think of Chromium as a tabbed window manager or shell for the web rather than a browser application. We avoid putting things into our UI in the same way you would hope that Apple and Microsoft would avoid putting things into the standard window frames of applications on their operating systems. The tab is our equivalent of a desktop application's title bar; the frame containing the tabs is a convenient mechanism for managing groups of those applications. In future, there may be other tab types that do not host the normal browser toolbar. -

NetBSD
NetBSD
NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices. NetBSD was originally released in 1993. Over time, its code has found its way into many surprising environments, on the basis of a long history of quality, cleanliness, and stability. The NetBSD code was originally derived from 4.4BSD Lite2 from the University of California, Berkeley. NetBSD is an entirely free and open-source UNIX-like operating system developed by an international community. It isn't a "distribution" or variant but has evolved over several decades to be a complete and unique operating system in the BSD family. NetBSD users enjoy a simple, well-documented, and fully integrated UNIX-like system that feels minimal, and in many ways traditional, while including many modern and interesting features, and support for recent hardware.Starting Price: Free -

Remote operations are done using ssh, scp, and sftp. Key management with ssh-add, ssh-keysign, ssh-keyscan, and ssh-keygen. The service side consists of sshd, sftp-server, and ssh-agent. OpenSSH is developed by a few developers of the OpenBSD project and made available under a BSD-style license. OpenSSH is incorporated into many commercial products, but very few of those companies assist OpenSSH with funding. Contributions towards OpenSSH can be sent to the OpenBSD Foundation. Since telnet and rlogin are insecure, all operating systems should ship with support for the SSH protocol included. The SSH protocol is available in two incompatible varieties, SSH 1 and SSH 2.Starting Price: Free -

syzkaller
Google
syzkaller is an unsupervised coverage-guided kernel fuzzer. Supports FreeBSD, Fuchsia, gVisor, Linux, NetBSD, OpenBSD, and Windows. Initially, syzkaller was developed with Linux kernel fuzzing in mind, but now it's being extended to support other OS kernels as well. Once syzkaller detects a kernel crash in one of the VMs, it will automatically start the process of reproducing this crash. By default, it will use 4 VMs to reproduce the crash and then minimize the program that caused it. This may stop the fuzzing, since all of the VMs might be busy reproducing detected crashes. The process of reproducing one crash may take from a few minutes up to an hour depending on whether the crash is easily reproducible or non-reproducible at all.Starting Price: Free -

cryptography
cryptography
cryptography includes both high-level recipes and low-level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests, and key derivation functions. Encrypt with cryptography’s high-level symmetric encryption recipe. cryptography is broadly divided into two levels. One with safe cryptographic recipes that require little to no configuration choices. These are safe and easy to use and don’t require developers to make many decisions. The other level is low-level cryptographic primitives. These are often dangerous and can be used incorrectly. They require making decisions and having an in-depth knowledge of the cryptographic concepts at work. Because of the potential danger in working at this level, this is referred to as the “hazardous materials” or “hazmat” layer. These live in the cryptography.hazmat package, and their documentation will always contain an admonition at the top.Starting Price: Free -

MidnightBSD
MidnightBSD
It includes all the software you'd expect for your daily tasks — email, web browsing, word processing, gaming, and much more. With a small community of dedicated developers, MidnightBSD strives to create an easy-to-use operating system everyone can use, freely. Available for x86, AMD64 and as Virtual Machines. The FreeBSD project has developed a reliable server operating environment, but often usability and performance on the desktop is overlooked. Scheduling, allocation of resources, security settings, and available application support should be tailored to desktop users. Many of the BSD projects are tailored to servers or older hardware. Others are distributions of FreeBSD with a nice graphical user interface, but still suffer from server-centric design under the hood. We did not fork FreeBSD as a result of a falling out, but rather as an excellent starting point.Starting Price: Free -
