Flox 1.0 – Open-source dev env as code with Nix
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…
Flox 1.0 – Open-source dev env as code with Nix launched on March 13, 2024 with 382 votes, #67 of 4,270 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Flox 1.0 is an open-source command-line tool that manages development environments using Nix. It allows developers to define, share, and reproduce consistent development setups across different systems and machines. The tool aims to reduce setup complexity and development cycle time by simplifying environment configuration and dependency management.

Flox2024 · flox.dev · ▲375Hey 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…
- FLFactorio Learning Environment – Agents Build Factories2025 · jackhopkins.github.io · ▲749
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…
Devbox – Easy, predictable shells and containers2022 · github.com · ▲515Devbox is a command-line tool that lets you easily create isolated shells and containers. You start by defining the list of packages required by your development environment, and devbox uses that definition to create an isolated environment just for your application. In practice, Devbox works similar to a package manager like yarn – except the packages it manages are at the operating-system level (the sort of thing you would normally install with brew or apt-get). See it in action: https://youtu.be/WMBaXQZmDoA
KeystoneMar 2026 · github.com · ▲125We 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…

Talanoa▲343Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
