## What it is
Flox is a CLI-based software environment platform built on Nix that creates declarative, cryptographically pinned, reproducible development environments from a single manifest file. It manages packages, environment variables, and services consistently across developer laptops, CI, and production without requiring Nix expertise.

## Use cases
- create reproducible development environments for my team
- pin exact tool versions across laptop, CI, and production
- replace Docker-based dev environments with a lightweight manifest
- share a dev environment with colleagues so everyone gets the same setup
- eliminate environment drift between machines
- manage project dependencies without learning Nix
- give AI coding agents a deterministic build environment
- build and publish custom packages for my organization

## When to choose
- your team suffers from 'works on my machine' drift across laptops, CI, and production
- you want Nix-level reproducibility without the Nix learning curve
- you need a lightweight alternative to multi-gigabyte Docker dev images
- you want to pin and govern your software supply chain across an organization
- you need consistent environments for AI coding agents and CI pipelines

## When to avoid
- you only need a simple language-specific package manager like npm, pip, or cargo
- your project requires Windows-native tooling or unsupported platforms
- you need full Docker-style containerization with isolated networking and runtime images
- you want a zero-dependency tool without a Nix-based catalog behind it
