Sawbuck is a log viewer and controller for Windows Chrome logging, and for other applications or plugins that use the logging facility in Chrome base.

Logging in Chrome is integrated with Event Tracing for Windows (ETW), which allows ETW controllers like Sawbuck to control log verbosity at runtime. The Chrome logging integration also captures the call stack at the logging site, which can then be resolved and displayed by log viewers such as Sawbuck. This is especially handy for plugin code, such as e.g. Chrome Frame.
