I'm new into this subject and, for what I've read, it seems that usability tests take place AFTER site development. They surely can have that property but if we draw a totally new web application, we should consider doing those, before going to the graphic design team.
Questions:
1) What Open Source tools (if any) do we have in order do build mockups and make them available to be tested ?
2) We need to record user think alouds and possible user clicks. Is there any open source tool that we may considered common and wealthy that we can use ?
Update:
Clickheat
It's open source, it does what it says, but your site must be life.
Usabilla
It allows sketch uploads but is hosted somewhere else. And its not open source:
Morae
Has it all.
BUT: windows only and expensive like hell - no open source.
Silverback
Not opensource. Mac only.
It says it's a usability software but I don't see any usability feature there. It records audio and video. Like many others.
It doesn't deal with meta information of any sort.
