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 Mockups 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. Mockups provides enough interactivity to replace prototypes most of the time, and makes it easy to collaborate and get feedback on your wireframes.
Mockup is available as a Desktop application, a web application and as a plugin to different wikis and bug trackers.
Mockups for Desktop
Mockups 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.
Mockups for Desktop saves and loads files from your computer, just like Microsoft Word or all the other desktop applications you’re used to using.
There are lots of ways to share your work with your team and with external clients when using Mockups for Desktop: you can send bmml files around, you can host them on a shared drive or on Dropbox, you can email people interactive, interlinked PDFs of your work.
Mockups for Desktop is balsamiq's fastest, most powerful wireframing editor, so it is recommend to get a copy, even when purchasing any of the other avaiable versions.
Mockups for Plugins
If you use Google Drive, Atlassian Confluence or Atlassian JIRA, you should try a plugin version of Mockups. The plugins integrate nicely with these platforms, whether you are hosting them yourselves or using them in the Cloud.
Mockups for Google Drive allows you to create, edit and share sketch-quality wireframes, all within Drive. You can even collaborate on your wireframes with others, in real time!
Mockups for Confluence allows you to add wireframes to your Atlassian Confluence wiki pages.
Mockups for JIRA allows you to add wireframes to your Atlassian JIRA issues.
