This is the project page for Chimera, a new project aimed at delivering a best-of-breed browser on the OS X platform. Chimera uses Cocoazilla, a variant of Fizzilla that consists of a UNIX back end wed to a Cocoa front end.

The cross-platform UI will be replaced with native Cocoa widgetry (such as customizable toolbars and a drawer for the sidebar). The plan is to produce only a browser (no other apps!), and to keep the UI as simple and as clean as possible.

Current project contributors include myself ( and Matt Judy ( If you are interested in getting involved, contact one of us! There's plenty of work to go around!

The initial checkin of Chimera has landed! A functional URL bar and back/forward/reload/stop are now all working in the app. A rudimentary sidebar has also landed.
