Founded in 2008, the goal of balsamiq is to help people create software that is easier to use. The company likes to compete on usability and customer service.
Balsamiq Wireframes is a small graphical tool to sketch out user interfaces for websites and web / Desktop / mobile applications.
It is a clean tool that lets you get in the flow and stay focussed on structure rather than colors and icons. Balsamiq Wireframes provides enough interactivity to replace prototypes most of the time, and makes it easy to collaborate and get feedback on your wireframes.
Balsamiq Wireframes is available as a Desktop application, a web application and as a plugin to different wikis and bug trackers.
Wireframes for Desktop
Wireframes for Desktop is an application you install on your computers and it runs on Windows, Mac and Linux. The license key is tied to humans, not particular machines.details
Wireframes for Plugins
If you use Google Drive, Atlassian Confluence or Atlassian JIRA, you should try a plugin version of Wireframes. The plugins integrate nicely with these platforms, whether you are hosting them yourselves or using them in the Cloud.details
