Switch your host/IP mappings in real time without editing your hosts file

What is LiveHosts?
LiveHosts is an ingenious Chrome extension designed to sidestep a prevalent bottleneck for web developers - the need to change host/IP assignments in the OS hosts file. While it employs a slightly sub-optimal approach, it successfully redirects requests to specified hostnames with an added Host header. Although this leads to displaying the hostname in the address bar following the IP, it impressively maintains consistency in handling all requests either to the IP or the hostname. However, users might experience some functional differences post-redirect such as potential alterations in parts of a webpage, differences in window.location values, and limitations in cross-origin requests.

LiveHosts is a Chrome extension that aims at providing a working (even if sub-obtimal) solution to a common nuisance that many web developers have to deal with every day. If you have multiple versions of your websites sharing the same host names on multiple environments, you often need to switch the assignments in your OS hosts file.

Other extensions (like the life-saving HostAdmin) can help with the cumbersomeness, but changes to the hosts file usually take an inconvenient amount of time to actually affect the browser.

Unfortunately, there is no way to make Chrome direct requests for a hostname to a specific IP without a standard redirect - you could set up a smart HTTP proxy, but it's often not possible or not convenient.

This extension settles for a sub-obtimal approach: requests to the indicated hostnames are redirected to the chosen IPs with an additional Host header. The browser's address bar reflects this behaviour showing the hostname right after the IP (e.g. The extension also tries to take care of all requests to either the IP or the hostname in a consistent way.


After the redirect, the user is effectively in a different domain that the one they expected. They may notice some functional differences:

  • depending on the server, parts of a web page referring to the site URL (like href and src attributes) could be different from the original
  • window.location has a different value that can potentially throw off JavaScript snippets
  • most Cross-Origin request won't work

Muy buena, justo lo que necesitaba, me encontraba usando un chromebook y no podia modificar el archivo hosts, pero con esta extención me resulto comodo usar una ip de mi red local.

Needs option to specify scheme such as "http://" instead of defaulting to "https://", which breaks a lot of dev setups.
