Sandbox (Deprecated)

This project is no longer maintained - please see the original project (https://github.com/markjaquith/Localdev) which now supports adding entries for other IP addresses.

Sandbox is a Ruby command line script to register domains that you sometimes use for remote or local development, and to quickly enable or disable development/host file entries for those domains. Only expected to work on OS X. Requires sudo access, as it is manipulating your hosts file.

Available commands:

  • sandbox add {domain} — adds the specified domain using the default sandbox IP (system default is
  • sandbox add {domain} {ip} — adds the specified domain pointing to the specified IP
  • sandbox destination {ip} - sets the default sandbox IP
  • sandbox remove {domain} — removes the specified domain
  • sandbox clear - removes all current entries
  • sandbox on — enables all saved entries
  • sandbox off — disables all saved entries
  • sandbox status — shows the current status of the tool (on/off status and current default destination IP)
  • sandbox list — lists the sandboxed domains
  • sandbox view {domain} - shows information on a sandboxed domain

Note: if sandbox development is on, add, remove, and clear commands will immediately update the hosts file and trigger a DNS flush.


To install Sandbox, use RubyGems:

gem install sandboxer


Your list of development domains is kept in /etc/hosts-sandbox. Your default destination IP is kept in /etc/hosts-sandbox-destination.
