24 alternatives to Flox

Hey Everyone! Ron here, part of the NixOS Foundation and building Flox. Just coming out of this years NixCon and pretty excited to show hn below :) As of today, NVIDIA officially recognizes Canonical, SUSE, CIQ, and Nix—via Flox—as supported distributors for CUDA. Full blog - https://developer.nvidia.com/blog/developers-can-now-get-cud... This is a huge win for the Nix community. For years, CUDA on Nix was possible but painful—builds could take hours, and redistributing prebuilt binaries was blocked by NVIDIA's licensing requirements. NVIDIA's growing engagement with key…

Flox is a development environment tool that lets developers build and share reproducible, cross-platform environments from over 100,000 software packages without using containers. It uses a declarative framework to… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Flox launched in 2024; newer entries below may have overtaken it.

    Hey HN, I'm Ron Efroni, CEO at Flox, and today we are releasing version 1.0 of our open source CLI, helping folks manage development environments everywhere.My own experience with development environments began with air-gapped systems, having to actually burn software to a CD to iterate over a very slow and expensive development cycle, sometimes reaching the server rack and realizing I have the wrong disk.... Fast forward to today and there are countless alternatives available backed by incredible compute resources, yet we somehow still find ourselves paying the price of long development…

    Keystone▲125

    We kept hitting the same wall: you clone some arbitrary repo and just want it to run without any configuration work. So we built Keystone, an open source tool that spins up a Modal sandbox, runs Claude Code inside it, and produces a working .devcontainer/ config (Dockerfile, devcontainer.json, test runner) for any git repo. We build on the dev container standard, so the output works with VS Code and GitHub Codespaces out of the box. Main use cases: reproducible dev/CI environments, self-describing repos, and safely sandboxed coding agents. Our goal is to encourage all repos to…

    Hello HN! I want to show you MyNixOS.com - a website I've been working on this year to make it easy to create and share Nix and NixOS configurations. Nix is a powerful tool to deploy software in a reproducible way, and with NixOS you can control your whole operating system through a declarative configuration. Starting out with Nix was exciting, but it definitely had a challenging learning curve. This made me start building a website focused on making it easier to create and share Nix flakes, which are the core unit of software deployment in Nix. Using the website, you can create flakes…

    CUDA is NVIDIA's language for GPU programming, allowing you to mix write CPU and GPU code in C++ in one file. By chaining a few projects that compile CUDA to OpenCL, then Vulkan, then WebGPU, you can experiment with this GPGPU language on any hardware.

    I'm Jack, and I'm excited to share a project that has channeled my Factorio addiction recently: the Factorio Learning Environment (FLE). FLE is an open-source framework for developing and evaluating LLM agents in Factorio. It provides a controlled environment where AI models can attempt complex automation, resource management, and optimisation tasks in a grounded world with meaningful constraints. A critical advantage of Factorio as a benchmark is its unbounded nature. Unlike many evals that are quickly saturated by newer models, Factorio's geometric complexity scaling means it won't be…

    Hey HN! Anibal, Sean, Vlad, Maxi and Karim here we're the co-founders of Kerno (https://www.kerno.io/). We're building a zero-hassle tool to help developers monitor and troubleshoot their services in a way that makes sense. No complex rollouts, no custom infra, no tons of instrumentation, no sidecars… none of that! Just a minimum effort, out-of-the box, highly contextualized and interactive experience so you and your team can focus on shipping! We basically scan your cluster resources, build usable abstractions on top of all the kubernetes craziness, identify monitor your…

    Hello HN! For the past few months, I've been building a Nix-specific CI service, and quite a few people have been productively using it, so I thought I'd Show HN it. You might be wondering why build a Nix-specific CI. It turns out its quite hard to get a really good CI setup for Nix without spending a lot of time or money on it (or both), and even then solutions don't tend to be optimal. Garnix, on the other hand, handles everything, and simply. Just create an account, install the GitHub app on the repositories you want, and you're good to go! Each package gets its own GitHub check, and…

    Hi there! I've been on-and-off working on TacOS for a few months, which follows some UNIX-derived concepts (exec/fork, unix-style VFS, etc) and is now able to run a port of Doom, with a fairly small amount of modifications, using my from-scratch libc. The performance is actually decent compared to what I expected. Very interested to hear your thoughts. Thank you!

    Tabs, splits, and tmux work fine until you have several projects open with logs, tests, and long-running shells. I kept rebuilding context instead of resuming work. Horizon puts shells on an infinite canvas. You can arrange them into workspaces and reopen later with layout, scrollback, and history intact. Built in 3 days with Claude/Codex, dogfooding the workflow as I went. Feedback and contributions welcome.

    Hello! This is Edgar and Robbie and we built nix-snapshotter. nix-snapshotter brings native understanding of Nix packages to containerd. We built this because Nix is a great fit for making efficient containers. They don't need an OS because Nix captures all dependencies exactly. However, the current process of creating Nix images is subpar because one needs to transform Nix packages into a format that container runtimes understand. Using nix-snapshotter, instead of downloading image layers, packages come directly from the Nix store. Packages can be fetched from a binary cache or built on the…

    Epho▲156

    Hey folks, Burak here. Epho is an API that allows running Claude Code, Codex or Opencode in a sandbox in the cloud. It abstracts away sandboxes, and allows running coding agents with a single HTTP request. Epho came out of our own struggles with building our own AI analyst: - Sandboxes give you bare machines; you need to configure them for agentic workloads. - Each agent behaves differently, and you need to build integrations with each of them. - Sandbox providers are not very reliable, which means you need to figure out a multi-provider strategy to avoid failures. - Logging, artifacts,…

    Finished my trading infrastructure project over the weekend - it’s called FLOX. Built in pure C++ (uses C++20 features), it’s a modular framework for building HFT systems, trading infra, market data feeds, or even something like a TradingView clone. Everything is open source: https://github.com/eeiaao/flox Docs: https://eeiaao.github.io/flox/ There are tests and benchmarks to keep it stable. Might add JS engine support later for scripting strategies. Open to feedback and contributions.

    Earlier this year, we released our open-source game engine [0] built with Rust, WebAssembly, and WebGPU. Today, we’re happy to announce the Ambient platform, which brings web deployment, server hosting, and more to the runtime. With Ambient, you can make a game, deploy it to the browser in one command, share your URL and instantly play with others, no downloads or installs needed. Our WASM use is innovative; it is being used as both a sandboxed runtime for user code, and as a way to run the entire Ambient runtime in the browser. This, paired with our ECS data model, enables a highly modular…

    Hello, this is Edgar! We are open sourcing nix-ninja, an incremental build system for Nix that leverages dynamic derivations. For those unfamiliar, Nix is a powerful package manager and build system that ensures reproducible builds via strict dependency isolation. However, one of its limitations has been that it builds packages as monolithic units - if you change one source file, Nix rebuilds the entire package from scratch. nix-ninja solves this by bringing compilation unit level granularity to Nix builds. It targets ninja build files, a format for describing build graphs output by popular…
