    On the same topic, check out this how-to on software development with Guix from the Cookbook (author here):

    https://guix.gnu.org/cookbook/en/html_node/Software-Developm...

    The idea was to show that there are several "levels" to take advantage of Guix for development, where the `guix.scm` file in David Thompson's blog post is the first level.

    I feel like declarative container-like dev environments (e.g. nix shell or guix shell, and so on) will become much more popular in the following years with the rise of LLM agentic tools. It seems that the aformentioned tools provide much more value when they can get full access to the dev environment.

    Sprites[0], exe.dev[1], and more services seem to be focusing on providing instant VMs for these use cases, but for me it seems like it's a waste for users to have to ssh into a separate cloud server (and feel the latency) just to get a clean dev environment. I feel that a similar tool where you can get a clean slate dev environment from a declarative description locally, without all of the overhead and the weight of Docker or VMs would be very welcomed.

    (Note: I am not trying to inject AI-hype on a Guix-related post, I do realize that the audience of LLM tools and Guix would be quite different, this is just an observation)

      As a Guix lover and LLM tooling enthusiast, I complete agree. Administrating my system via Claude Code is so much easier. LLMs work better on a system that's hackable via text.

      random note: there's `guix shell --container --emulate-fhs`.

    Guix looks really tempting to me because i find guile scheme so much more pleasant than nix. But i heard there are not that many packages in Guix. I wonder if some sort of transpiler from nix derivations to guix package definitions would be possible.

      You can just visit https://repology.org/ and see that GNU Guix has the 5th largest repository, ahead of Fedora and Gentoo. This does not include any proprietary packages, which can be added using https://gitlab.com/nonguix/nonguix (though gitlab seems to be dying for me right now?)

      I've been running GNU Guix for five years now, after lots of distro hopping, including to and from NixOS. I left Nix because I found the documentation (particularly regarding the language) to be a struggle to work with (though I imagine it's improved since then).

      GNU Guix + nonguix + flatpak is perfectly suitable for everyday use.

      You can run Nix packages on Guix if there isn't a "native" package for it. Look at nix-service.

      https://guix.gnu.org/manual/1.5.0/en/html_node/Miscellaneous...

      I've never felt the need myself. If something is missing, I add it and I think that is the real fun in running Guix because creating your own well defined package or service is deeply rewarding.

      Anyway, you can find people using it in the wild either by search engine[1] or with Toys[2] which is also handy for finding examples of missing packages too.

        You can stop recommending that flow (nix on guix), it's not good. You'll know if you try it.
    • heavyset_go 12 hours ago
      This is where I'm at after using Nix for a few years for different use cases. I never want to write it again, and would welcome a Scheme over Nix.
    • sidkshatriya 8 hours ago
      The nix language is maximally lazy. It does not evaluate things it does not need to. This is good because you don't want it to burn CPU building things (very expensive expressions!!) that it will ultimately not need for final derivation. I'm wondering if guix scheme is suited well for this task:

      (a) evaluation is eager

      (b) lots of variable mutation.

      But perhaps lazy evaluation and lack of variable mutation in guix scheme is not such a problem after all for a nix _like_ system -- I don't know.

      • helibom 6 hours ago
        I'm still new to both Guile and Guix, but I've been reading the Guile and Guix reference manuals recently and I think some of your concerns about eager vs. lazy evaluation of packages are addressed by Guile's quoting mechanism, more specifically "quasiquote" [1]. This quoting mechanism allows passing around references to package definitions and whatnot, without actually evaluating those expressions until build time. Guix extends quasiquote to create something called "G-expressions" [2], which are even more so fitted to something like the Guix/Nix build system.

        Im very familiar with Nix or the language, but why would interpreting guile scheme for package management be expensive? What are guix and nix doing that would require evaluating everything lazily for good enough performance?
        • Hasnep 4 hours ago
          It's not the Nix/Guile that's expensive, it's situations like:

              let chromium = pkgs.chromium; in 1 + 1
          
          In a maximally eager language you'd need to wait for the entirety of Chromium to build before you can find out what 1 + 1 is.
          • atiedebee 4 hours ago
            I checked the spec and Scheme R5RS does have lazy evaluation in the form of promises using "delay" and "force", but I can see why explicitly having to put those everywhere isn't a good solution.
      • attila-lendvai 3 hours ago
        "lots of variable mutation" is more like "variable mutation is no impossible, but not common".
    • whompyjaw 13 hours ago
      Im with you. As an emacsen, i feel it’s natural for me to use Guix, but nix is so so much more popular… :/
      • digiown 13 hours ago
        Guix being a GNU project the purism also doesn't help. Just look at this: https://github.com/nonguix/nonguix

        I don't even disagree that nonfree software is bad, but blaming the users who often have no choice in the matter (e.g. drivers) is the wrong way to go.

        • allan-a 5 hours ago
          nonguix is similar to debian's non-free sources. It's also maintained by many of the same contributors to guix. Enabling it is also similar to how you enable it for Debian. I have never seen anyone blamed or shamed for using nonfree drivers by the guix community, which I can say has been a very warm and welcoming community.
          • attila-lendvai 3 hours ago
            it does happen, and it happened to me, too.

            but the attitude has been changing recently from active shaming for even mentioning non-free stuff, to passive acceptance of pragmatically pointing a newcomer to nonguix.

        • herewulf 12 hours ago
          It's a little inconvenient but for example my Framework laptop Intel WiFi chip requires a binary blob and I want aware of this. Now that I am, I can make better hardware purchasing decisions. There are plenty of alternatives that don't require that blob and it's the only thing I need from the no free channel.
          • freeopinion 12 hours ago
            Are there really a lot of alternative Wifi chips that don't require closed blobs? Do you have a list?

            Are they found in any laptop that is reasonably available on the market?

            I don't think that Guix is punishing users by not supporting non-libre hardware. They are making a choice in what they develop and anybody of similar mind can join their effort.

            The nonguix folks are practical. It just stinks that nothing ships with a Wifi chip that doesn't require nonguix pragmatism.

          • digiown 10 hours ago
            I really don't think you can gain much realistic freedom going without the blob. The powers that be will never let you have a freely modifiable radio transceiver.

            The blob is better viewed as a part of the hardware in this case. What's most likely to happen to get rid of the blob is to just put it on the non-modifiable parts of the device. Viewed in this way, the blob is at least something you can practically inspect, unlike the firmware on the chip itself.

            See also the discussion on CPU microcode:

            Open hardware is mostly a lie.

            They all run proprietary blobs inside and out. It's ridiculous gatekeeping to say that on the kernel level it's bad, but below it I just put my head in the sand and disregard the millions of lines of closed-source code.

    • benreesman 9 hours ago
      I compile nix derivations to well-posed effect/coeffect/graded monad algebra so I can do real bill of materials and build on an action cache engine maintained by professionals, but that's mostly for long-tail stuff.

      These days with a la carte access to all of the container ecosystem primitives as nice, ergonomic, orthogonal operations I don't really see the value in nixpkgs. Don't really see the value in a container registry either: a correctly attested content addressable store with some DNS abbreviations is 100 lines of code because mostly it's git and an S3 shim.

      The category error at the heart of nixpkgs is that the environment in which software is compiled need resemble the environment in which it executes. Silly stuff. So whether you're a patchelf --rpath ... Person or an unshare --bind-mount Enjoyer (isomorphic), just remember, in 2026 the guy with the daemon that runs as root does not want you to have nice things.

    • arminiusreturns 11 hours ago
      Now if we could just get people to combine Guix and other guile scheme packages that are awesome like mcron into their stacks, and then backfeed more fixes into the ecosystem, we have a real chance at helping GNUland!
  • davexunit 13 hours ago
    Always interesting to see an older article come back around. I could probably update this a bit for 2026 but my workflow is just about the same now as it was then. Guix is good and just released 1.5.0, check it out.
  • tetris11 5 hours ago
    I love Guile over Nix syntax, but the one killer feature Nix has that Guix doesn’t is making a single static binary of common programs and then deploying them elsewhere.

    In Nix, this is a single flag. In Guix, you either deploy with all libraries on a custom /guix path, or nothing.

      How do you do it in nix?
  • nickez 2 hours ago
    What if a piece of software isn't packaged, like for example the ARM GCC toolchain. In a Dockerfile I just need to curl and unpack it. How do I solve that with guix?
  • pmarreck 14 hours ago
    both guix and nix are 1000% better for setting up and managing per-project deps deterministically

    > Dockerfiles are clunky and the rather extreme level of isolation is usually unnecessary and makes things overly complicated

    I agree, for local development docker is often overkill.

    However, for production it's absolutely not overkill. And since pretty much all projects are intended for production at some point, they'll need a Dockerfile and docker compose or some other equivalent.

    And at that point, you're maintaining the Dockerfile anyway, so why not use it for local dev as well? That way your dev and production environments can be close to identical.

    Guix looks nice - probably nicer than docker for dev work. But is it nice enough to justify maintaining two separate systems and have your dev and production diverge?

  • rudhdb773b 6 hours ago
    I love Guix documentation, but unfortunately I've had to stick with Nix because its more polished with a large library of packages.

    LLMs have also made writing syntacticly correct Nix scripts much easier, so I don't miss Guix's Guile that much.

  • sohrob 9 hours ago
    I wanted to go all-in on Guix but the installation process was made too difficult due to the lack of non-free software available during install time. I wish they would take the Debian approach and leave it up to the user to decide which packages they would like installed on their system or not.
    • icen 7 hours ago
      There’s nonguix for access to non free drivers and such. I think that system crafters have some installable images if you don’t have a current guix install to build one

      It’s regrettable that this is necessary, but with so few Ethernet ports on laptops it’s harder to install these things without access to WiFi.

    How is the scheme syntax in any way an improvement over JSON? Can't they build the same thing but use JSON - which everyone already uses - instead of pushing a new verbose syntax?
    • cess11 1 hour ago
      I think it would be tricky to develop a package manager in JSON.
  • arikrahman 13 hours ago
    Honestly I'm just glad that this declarative approach is steadily being realized. It hasn't hit mainstream adoption yet, but it gives me hope that this headline is making the rounds.

    Docker is, as the article describes, just a bandaid and the symptom of unthoughful development foundations.

    In the long term, Guix may win out. Probably not in my life time though. But it's a win for developers, and nix really isn't so bad with everyone vibecoding away it's complexity anyways.

    • wswin 11 hours ago
      I think they're two different tools. Containers are great for production environments. Beside reproducibility, they also give control over resources and manage virtual devices. Things that are rather not needed during development.
      • akshitgaur2005 7 hours ago
        That is also an option with guix --container
    • herewulf 12 hours ago
      You can even generate Docker images deterministically with Guix. :)

    Guix asking for donations from propietary websites it's a disgrace to GNU.

    But i woudn't expect less from some hijackers.
