Flox Environments

Flox sits between language version managers and containers: you get a declarative TOML manifest that pins system packages, databases, and toolchains across macOS and Linux without container overhead. Built on Nix with access to 150,000+ packages. The real win is for AI coding workflows. Claude can install PostgreSQL, Redis, or any compiler into a project-scoped environment without sudo or polluting your system, and the resulting manifest commits to git so your team reproduces it instantly. If you're tired of "works on my machine" or wrestling with Homebrew differences between Intel and ARM Macs, this handles it. The manifest lives in .flox/env/manifest.toml and activates with one command.
