I want to try it in my localhost, but everytime it says that cookies must be enable. They are enable, and i can enter in coach after cleaning cache, cookies and trying to enter several times. I do not have a domain yet, and dont want try free ones, just want to do it in my local machine.
Working on localhost is just the same as on a hosted machine.
If you are a Windows user, the easiest way of working with Couch would be to download its portable installation from http://www.couchcms.com/products/
For other platforms please use a local stack like MAMP, XAMPP etc.
Hope this helps.
