Possible disadvantages of FreeBSD

  • Hardware Compatibility
    FreeBSD may have limited support for certain hardware devices compared to other operating systems like Windows or Linux.
  • Learning Curve
    The system can be complex for new users, requiring a significant amount of time and effort to become proficient, especially if they are accustomed to more user-friendly environments.
  • Smaller Community
    Compared to Linux, FreeBSD has a smaller user and developer community, which might result in less community-driven support and fewer available resources.
  • Limited Desktop Support
    While FreeBSD can be used on desktop systems, it is primarily optimized for servers and might not offer the same level of convenience or support for desktop applications and environments as Linux distros.
  • Software Availability
    Although it has a vast Ports Collection, some software might not be available or can be more challenging to compile and maintain than on Linux.

OpenBSD features and specs

  • Security
    OpenBSD is known for its focus on security. It undergoes rigorous code auditing, has a proactive security approach, and includes features like secure memory management and privilege separation.
  • Stability
    The operating system is well-known for its stability and reliability, due to its minimalist approach and an emphasis on creating a robust user experience.
  • Documentation
    OpenBSD provides comprehensive and thorough documentation, making it easier for users to understand and utilize its features effectively.
  • Cryptography
    The system includes strong cryptography and has been a pioneer in developing and implementing various cryptographic techniques and software.
  • Simplicity
    OpenBSD focuses on simplicity in its design and functionality, reducing unnecessary complexities and streamlining the user experience.

Possible disadvantages of OpenBSD

  • Hardware Support
    OpenBSD may have limited hardware support compared to other operating systems, which can pose challenges for users with modern or specialized hardware.
  • Software Availability
    It can lack the breadth of software availability found on more popular platforms like Linux or Windows, which might limit its use for certain applications or tasks.
  • Performance
    Some users may find that OpenBSD prioritizes security over performance, resulting in slower performance compared to other systems optimized for speed.
  • Limited Community
    The user community for OpenBSD is smaller relative to other open-source operating systems, which can lead to less support and community-driven resources.
  • Learning Curve
    For new users, especially those not familiar with Unix-like systems, OpenBSD can present a steep learning curve due to its unique configuration and system management.

FreeBSD Reviews

Best free Linux router and firewall distributions of 2023
OpenBSD and FreeBSD are actively developed and are very capable, but these systems require a high level of understanding of operating system internals and low-level networking to be used as routers.

With "Linuxulator," FreeBSD has compatibility with Linux binaries. Linuxulator can run unmodified Linux binaries without using virtual machines or emulation. Additionally, FreeBSD has tens of thousands ported libraries and applications.

OpenBSD Reviews

Best free Linux router and firewall distributions of 2023
These systems are not intended for routers. They are general-purpose operating systems and should not really be used as routers. Similar to OpenBSD and VyOS, you will have to configure everything by hand without a Web Interface. It's easy to make a mistake and leave a hole that exposes internal systems to attackers.

  • I've never used FreeBSD and have some questions
    Aside from being UNIX based, what similarities does it share with Linux? Both have monolithic kernels. Source based build systems are offered (ports, which are like the portage system on Gentoo) as well as binary build systems (pkg, which is like apt, yum, pacman, etc.) Both offer a lot of free software, though more licenses are compatible with FreeBSD like CDDL, which is not compatible Linux. Both let you... Source: over 1 year ago
  • FreeBSD turns 30 today!
    There's no mention of a birthday on their site, and its footer says 1995-2023. That must be just the site, because Wikipedia tells me FreeBSD's initial release was indeed, but not quite, 30 years ago, November 1st 1993. Still no birthday. Source: almost 2 years ago
  • Computer
    I'm not the right person to ask this -- I just run it on whatever I happen to have. But I think sleep and wifi (for example) have issues with different hardware, so you'd have to do your homework. The FreeBSD handbook on freebsd.org is always very helpful to me. You can try it out with a live cd / thumbdrive to see how much supported hardware you've got. My Lenovo X1 from a couple years ago works for what I... Source: almost 2 years ago

  • Configuring a simple router with OpenBSD
    OpenBSD is a security-first Unix-like operating system belonging to the BSD family of operating systems. It is best known for the OpenSSH project founded in 1999 under the OpenBSD umbrella which has garnered widespread adoption beyond OpenBSD, including the infamous Linux operating system and even Microsoft Windows (since Windows 10). - Source: dev.to / over 1 year ago
