Why NixOS is my choice for Development?

A year ago, my Void Linux setup broke because my battery died in the middle of an update. That single moment corrupted system libraries, and even the default package manager started throwing segmentation faults. The system was effectively unrecoverable. That experience pushed me to look for something more reliable. I didn’t just want a distro—I wanted guarantees. That’s what led me to NixOS.
The Pain
NixOS is not beginner-friendly, and there’s no point pretending otherwise. At first, it feels rigid. Your system behaves like a specification rather than something you casually tweak. Want to install software? You declare it in a config. Want to change system services like systemd? You declare it in a config. Want to modify your environment? Same rule. Then you rebuild the system instead of “just installing things.” It feels slow. It feels restrictive. It feels like overkill. But that rigidity is the entire point. NixOS uses declarative configuration, meaning your entire system is defined in code. Instead of mutating your system step-by-step like traditional distros, NixOS builds a new system configuration and switches to it only when everything succeeds.
Why This Matters
On most Linux distributions, updates are imperative: they directly modify your current system. If something fails midway (like my Void Linux incident), you can end up in an inconsistent and broken state. NixOS avoids this entirely through: Atomic upgrades – changes are applied as a whole, or not at all Rollbacks – you can boot into previous working configurations Reproducibility – the same config produces the same system every time Isolation – packages don’t overwrite each other in unpredictable ways This is not just convenience—it’s a fundamentally different model.
The Save
My system broke again. At that point, I seriously questioned my decision to use NixOS. It’s supposed to be stable, so why was I dealing with another failure? This time, the issue was hardware—my SSD had failed and needed replacement. After installing a new drive, I restored my NixOS configuration. Within minutes, my entire system was back: same tools, same environment, same setup. No manual reinstallation. No “what did I forget this time?” No hidden dependencies or missing steps. That’s when it clicked. All the time spent writing configuration wasn’t overhead—it was stored effort.
Developer Experience
The developer experience on NixOS follows the same pattern: painful upfront, stable long-term. Setting up environments—especially for things like Android development—can feel like solving a puzzle. You need to understand flakes, dependencies, and how Nix expressions work. But once configured: Your environment becomes reproducible You avoid “works on my machine” problems You can reuse and share configurations You don’t have to redo setup across machines A well-written flake.nix can eliminate hours of setup work in the future.
Trade-offs
NixOS is not without downsides: The learning curve is steep Error messages can be difficult to interpret Documentation is powerful but fragmented Builds can be slower compared to traditional package managers These are real costs, especially early on.
Who Is NixOS For?
NixOS is a good fit if: You value reproducibility and stability over convenience You frequently rebuild or switch environments You want your system configuration to be version-controlled You’re willing to invest time upfront to save time later It may not be ideal if you just want something that works immediately with minimal effort.
Conclusion
NixOS doesn’t feel natural at first. It forces you to think differently about your system—not as something you modify, but as something you define. That shift is uncomfortable. Progress feels slow in the beginning, and the friction is real. But that effort accumulates. It doesn’t disappear. When things break—and eventually, they will—that stored effort is what brings everything back in minutes instead of hours. NixOS trades short-term convenience for long-term reliability. And over time, that trade starts to make sense.
A final note I want to say is It's your system and at the end of the day you should be able to do anything you want. There will be time when speed will be more important than stability and that's exactly why I keep an ubuntu docker, case sometimes speed > stable.
