## What it is
Cachix is the command line client for the Cachix Nix binary cache hosting service, letting users push, share, and pin Nix store path binaries. It also configures caches in nix.conf and manages remote Nix-based systems via Cachix Deploy.

## Use cases
- push nix store paths to a shared binary cache
- cache nix builds between CI runs
- share prebuilt binaries across a team
- configure a binary cache in nix.conf
- watch /nix/store and upload newly built paths
- pin store paths to prevent garbage collection
- manage remote nixos deployments with cachix deploy

## When to choose
- you use Nix and want to avoid rebuilding software in CI or across machines
- you need team access control and garbage collection for a Nix binary cache
- you want to speed up nix-build and nix-shell workflows

## When to avoid
- you don't use the Nix package manager
- you need a fully self-hosted binary cache without the Cachix service (consider alternatives like a plain S3/Nix cache)
