What learners say

“Choosing nixcademy for our NixOS trainings has been an invaluable building block in our Shift-Left Strategy at secunet. The trainings have not only enabled us to deliver more value to our customers at a faster pace but have also proven to be a cost-effective way to train our staff. The feedback from the clear majority of participants was overwhelmingly positive. Without a doubt, I would happily purchase Nixcademy trainings again.”

“The Nix(OS) workshop was a valuable experience that has opened up many new possibilities for us. It was particularly impressive how easy it is to create reproducible environments for training neural networks with Nix. Thanks to the knowledge we learned, we have already been able to successfully create some packages and contribute to nixpkgs.”

“Nix is a very promising technology, but I found it very difficult to get started. The Nixcademy helped me a lot to use Nix effectively in my work. The training has given me the practical skills I need to fully evaluate and use Nix.”

“Having recently embarked on building our products with Nix & NixOS, the training provided by nixcademy has been a game-changer for our team. The steep learning curve was made manageable through the comprehensive and well-structured program. The trainer's deep expertise and ability to simplify complex concepts made the learning process enjoyable and effective. I wholeheartedly recommend nixcademy trainings to my colleagues.”

Frequently asked questions

Is it really free?

Yes. A free account lets you watch every free course in full. There is no trial period and nothing upgrades automatically. Premium courses are separate, optional one-time purchases.

Do I need a credit card to sign up?

No. Creating an account only takes an email address. You are only asked for payment details if you decide to buy a premium course, and that checkout is handled by Paddle.

What can I see without an account?

You can browse the whole course library, read every course and lesson description, and preview the content without signing up. Pressing play on a video is the only thing that needs a free account.

Are the premium courses a subscription?

No. Each premium course is a one-time purchase with lifetime access — buy it once and revisit every lesson whenever you need it.

How is this different from Nixcademy team training?

The courses here are self-paced videos for individuals. Our instructor-led team trainings at nixcademy.com (where we train hundreds of engineers and administrators every year) are customized to your team and much more personal: your questions get answered in depth, and we help you apply Nix directly to your own projects and products. The trainings are organized right here on this platform: participants download their slides, set up access to their personal training machines, and follow everything on the training page.

Can companies get their own training content here?

Yes. Some companies get access to internal training videos created just for them — there are already many more training videos on this platform than public visitors can see. Companies can also set up bulk contracts so their employees learn self-paced with our course library. Get in touch via nixcademy.com.
