Devbox

Devbox creates instant, reproducible development environments using Nix packages without the complexity of learning Nix itself. Define your project's dependencies in a simple JSON file and Devbox sets up isolated shells with the exact versions of tools you need — Node.js 20, Python 3.12, PostgreSQL 16, etc. No Docker containers, no VMs, just native-speed tooling. It solves the 'works on my machine' problem while keeping environments lightweight and fast to create.
