Built on top of the Nix package manager, it is completely declarative, makes upgrading systems reliable, and has many other advantages. ## NixOS Reviews ### 1. Manage your entire Linux system configuration using a single language **Rating:** 4.5/5.0 stars **Reviewed by:** Neil M. | Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** September 26, 2019 **What do you like best about NixOS?** • One language and syntax to configure every aspect of the system • Dependable and accurate control of system states • Ability to back out upgrades, even if the system is unbootable • Create isolated, disposable environments for trying new packages • Create software build environments with just the dependencies you need • No worrying whether installing some dependency or tool is going to mess up your system **What do you dislike about NixOS?** • Closed-source binaries are harder to install and keep working • Not everything works all the time **Recommendations to others considering NixOS:** Take some time to understand the paradigm since it's significantly different from other Linix distros. You can also kick the tyres a bit by using Nix on top of a regular Linux distro, but keep in mind that using Nix to manage the OS itself is a huge step up from just managing packages. **What problems is NixOS solving and how is that benefiting you?** • Fearless system upgrades! • No accretion of junk over time • A sane software development environment that uses a single paradigm for all languages ### 2. it was different but great **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Package/Freight Delivery | Small-Business (50 or fewer emp.) **Reviewed Date:** July 10, 2020 **What do you like best about NixOS?** i thought it was a little complicated at first.. but once i started using it i got comfortable **What do you dislike about NixOS?** at first it was a little complicated like i explained earlier, but honestly its nothing i can say negative or to dislike at time **Recommendations to others considering NixOS:** Do not get impatient on using it **What problems is NixOS solving and how is that benefiting you?** upgrading some systems is the benefits so far, but still figuring it out ### 3. NixOS user and NixOS server admin, devops **Rating:** 5.0/5.0 stars **Reviewed by:** Danylo H. | DevOps/AS3/C++ Developer, Entertainment, Small-Business (50 or fewer emp.) **Reviewed Date:** October 18, 2017 **What do you like best about NixOS?** - reproducibility and deduplication, and many other benefits from Nix package manager - configuration management united with system configuration - actually, quite fast for deploys - upgrades can be rolled back without fear, because it doesn't manage state - functional language as configuration language. Immutability, referential transparency and laziness are really cool! - good and evolving community - easy to patch packages, easy to create new packages (Nix benefits) - open world module system for configuration, where it is easy to manage dependencies and harder to make errors **What do you dislike about NixOS?** - poor reflection support (why is disk space occupied, why is this option enabled) - poor stackoverflow community - often you should dive into deep internals of NixOS and Linux to figure out how to fix/overcome problems - has bugs - security updates (and unattended upgrades) exist but are a bad story - project is still in experimental state, so enterprises rarely adopt it - community has not enough manpower - typical NixOS admin should be more proficient than typical Ubuntu admin - doesn't have support for all features from upstream (for example, reloading services instead of restarting is still an open problem) **Recommendations to others considering NixOS:** Learn Nix language Don't be afraid to dig into NixOS internals Don't be afraid to fork it and modify when in need **What problems is NixOS solving and how is that benefiting you?** Move system configuration into some central place Managing root servers with many-many services and containers. It's really cool that you can remove some service from configuration and it will be really removed from system - no need to mark explicitly to remove some service. This helped to keep servers in a clean state ### 4. I consider it to be the future, but needs documentation work **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Program Development | Small-Business (50 or fewer emp.) **Reviewed Date:** March 03, 2016 **What do you like best about NixOS?** Ease of deployment and reproducibility of the system **What do you dislike about NixOS?** Poor documentation, making it hard to create new packages, services or builds on the Hydra CI service **Recommendations to others considering NixOS:** Please, contribute to the docs whenever you can. **What problems is NixOS solving and how is that benefiting you?** Deployment of web services. ## NixOS Discussions - [very good](https://www.g2.com/discussions/very-good-5fc8ff0e-fd91-401e-b68d-6751d8742198) - 1 comment, 1 upvote - [View NixOS pricing details and edition comparison](https://www.g2.com/products/nixos/reviews?section=pricing&secure%5Bexpires_at%5D=2026-06-25+02%3A44%3A39+-0500&secure%5Bsession_id%5D=0347145c-6520-414c-aa30-76ee174a49e2&secure%5Btoken%5D=e0b74343fe32f63e10ca2c6e6db2ba0cb5fc3b3f2bd3daff2e58b8d9e624d4fb&format=llm_user) ## Top NixOS Alternatives - [Red Hat Ansible Automation Platform](https://www.g2.com/products/red-hat-ansible-automation-platform/reviews) - 4.6/5.0 (369 reviews) - [GitHub](https://www.g2.com/products/github/reviews) - 4.7/5.0 (2,301 reviews) - [ServiceNow IT Service Management](https://www.g2.com/products/servicenow-it-service-management/reviews) - 4.5/5.0 (1,736 reviews)
