A simple CLI tool to block distracting websites on macOS by modifying /etc/hosts.

make install

Or manually:

go build -o focus .
sudo mv focus /usr/local/bin/

# Block all configured sites
focus block

# Unblock all sites
focus unblock

# Check current status
focus status

# Open config file in editor
focus config

Sites are stored in ~/.config/focus/sites.txt (one domain per line):

x.com
linkedin.com
discord.com
news.ycombinator.com

Edit this file to add or remove sites. Changes apply on next focus block.

• Adds 127.0.0.1 <domain> entries to /etc/hosts
• Flushes DNS cache after changes
• Requires sudo to modify the hosts file
