Google Chrome Canary

About

Google Chrome Canary is a nightly build aimed at developers who want to get on the bleeding edge of the web. It is updated nightly, so developers can follow the latest changes as they arrive.

Canary is intended for developing websites for the next version of the web and for testing cutting-edge web platform APIs. The website warns that Canary can be unstable, so users should expect possible problems.

In short, Canary is a developer-focused preview of upcoming web technology, with the trade-off that its builds may not be stable.
