## What it is
Gas Mask is a macOS application for managing and switching between multiple hosts files. It runs in the menu bar, supports local, remote, and combined hosts files, and updates /etc/hosts with the active configuration.

## Use cases
- switch between different hosts files on macos
- block websites by editing the hosts file
- sync a remote hosts file like StevenBlack's automatically
- combine multiple hosts files into one
- manage local development domain overrides

## When to choose
- you need to frequently switch hosts file configurations on macOS
- you want automatic syncing of remote hosts blocklists
- you need to merge several hosts files into one active file

## When to avoid
- you are on Linux or Windows
- you need a cross-platform or CLI-based hosts manager
- you only make rare one-off edits to /etc/hosts
