Chrome Canary is the less stable version of the Google Chrome operating system. Canary has cutting edge features compared to the developer’s build. These features are tested thoroughly before being pushed into beta build. Canary gives the user the useful option of running the advanced version of Chrome without fully committing to alpha testing.
One of the primary reasons for introducing the Chrome canary is to speed up Chrome's development cycle. With help of public, Google can test new features and collect user feedback and statistics more quickly and easily. The test results that are derived from users help the Chrome team to resolve issues in the software more quickly and roll it out to all Chrome users.
