* Error Aggregation - Backtrace automatically groups errors based on the type of error you’ve encountered. * Workflow Integrations - Backtrace integrates with your existing workflows to streamline notification, communication and collaboration when errors occur. * Automated Classification - Backtrace gives you a head start in root-cause analysis. * Powerful Debugging - Backtrace provides powerful web and terminal UIs that allow you to perform complex debugging tasks in your preferred environment. * Detailed Data Faster - Generate detailed backtraces with full stack crawling orders of magnitude faster than today’s debuggers.

* Defensive Reporting - Processes that crash often end up sustaining considerable damage before the kernel takes action to terminate them. This can result in secondary crashes, where the crash handling code itself is unable to operate correctly and fails. We’ve invested in making our file handling code extremely defensive, so parsing cache files can’t crash unexpectedly. * Stack Unwinding - One of the most abstruse aspects of crash detection is stack unwinding, the seemingly omniscient ability to determine historic code execution that directly lead to the crash. Our SDK determines the calling instruction that works in the case of objc_msgSend and many other methods that conform to Apple’s iOS ABI. * Mach Exceptions - We capture crashes using the lowest level system available on iOS and OS X. The Mach Exception API makes it possible for us to capture every crash, consistently, and without some of the indeterminate behavior of other mechanisms. This also gives us data that much more closely matches what a developer would see in Xcode.
