I'm looking for a url tracking service where I can generate urls (for which I can make QR codes) and later I would need to edit the redirect URL. So the problem is, currently I don't have the final URLs, but the QR codes needs to be created, so I would need URLs like ex: www.awesometracking.com/sj9Uf and later when I have the final URL for my site, in the tools admin area, I can set for the sj9Uf id, the target link.
Maybe I'm missing the right keywords, but I cannot find anything, so any idea will help.
I think I found one, which seems to be good: http://yourls.org/ I will test it out, but I'm still curious about other possibilities.
