Free alternative to BrowserCam
BrowserCam has long been the best tool for testing websites in a multitude of situations; however, it isn’t free, so its usefulness is limited for people who just want to test a new design quickly: enter BrowserShots. This free website has most of the features developers will need to test their sites; however, unlike BrowserCam, there seem to be waits of up to 20 minutes for some OS/Browser combinations, so it is better for casual testing to ensure compatibility rather than live tweaking—it does have a detail page to show how long your wait will be.
