TL;DR - None of this would be here without all of the Nix contributors. Below is only a few of the amazing Nix moments of 2022. If you Nix, keep Nixing. If not, start Nixing. Comment more great Nix that happened last year 
This is also a followup to our discourse post here Nix 2022, What Was Great? - Development - NixOS Discourse
Nix in the Numbers & Community Survey
- We launched the first ever community survey and received over 2k responses, giving us the first cross community glimpse into how/why/where Nix is happening. You can check out the full recap here. 2022 Nix Survey Results - Announcements - NixOS Discourse
- Nixpkgs crossed 200,000 Pull requests/Issues on GitHub
- Over 80k people visited NixOS.org when we launched the last release
Nixpkgs is the 7th open-source project on GitHub by contributors <3
Nixpkgs is the largest and freshest repository
Even the older and unmaintained 22.05 release has more fresh packages than the current 2023 AUR. Graphs - Repology
Nix star count keeps doubling
If there are more interesting metrics, ping them in the comments and we will add it in!
Teams
The community established new teams in critical areas such as:
- The Nixpkgs Architecture Team, with the goal of improving Nixpkgs using impactful changes
- The Nix Documentation Team, born out of the wide-spread desire for better official documentation
- The Nix Team, created to stabilize Nix development and maintenance, distributing the responsibility to more people than just Eelco
Current teams kept delivering and supporting the community across all key pillars of the community, keeping Nix alive and well. Nix Community (nixos.org)
We’ve also kicked off a part of a first step in our plans to Empower Teams by beginning to test out a new team structure in collaboration with the NixOS Foundation Board to ensure critical areas in the community are always up & running by receiving more support and having more accountability.

We had 21 participants, 5 team coordinators, 6 project leads, 6 tech whizzes. 38 in total!

(The NixOS Foundation grant/funding program will also be supporting these events!)
NixCon in Paris - All Recordings
Finally, we got together and sipped some Club-Mate. For the first time in 3 years we all got together in Paris for three days of presentations, discussions and good times. With over 200 in person and hundreds live online we kicked off talks showcasing the staggering breadth of the community: people successfully using Nix for working on particle accelerators, computational chemistry, satellites, and even resuscitating Flash for a legacy enterprise migration. Check out the presentations and recordings!
One NixCon equals 16 hours of content, 200 iconic mugs and ?? numbers of beers (purchased largely by @matthewcroughan )
Huge thanks to all of the organizers and everyone else that made NixCon possible!

2023
If calendar years were reproducible, it would get boring quickly. 2023 is just getting started and there’s a lot in store for us! Nix is officially celebrating 20 years in March with various efforts going around that will be announced over the coming weeks. The NixOS Foundation is launching a grant/funding program to support various Nix meetups/sprints/efforts and will be working on bringing more support into our general community. We are spreading Nix to the world, with tables/booths and devrooms across leading Open Source events worldwide (link SOOCON / FOSDEM / SCALE) and as you can clearly see if you’ve reached this portion of the post… lots and lots more coming in from every part of the NixOS community daily.
I wish us all a year filled with health, happiness and Nix!
Thank You.
