Git.io Link Shortener - antonizoon/antonizoon.github.io GitHub Wiki

One of the more interesting "hidden" features of Github is the ability to create a Git.io shortened link! This service is only for Github links, and was developed by technoweenie and atmos as an experiment with Riak and Guillotine.

This link shortener will probably last about as long as Github exists; unlike other services.

However, you can set your own vanity shortened URLs, using a secret CURL command (on bash):

$ curl -i http://git.io -F "url=https://github.com/technoweenie" \
    -F "code=t"
HTTP/1.1 201 Created
Location: http://git.io/t
