Honeybadger's breadcrumbs make dealing with complex errors easier because they let you see the sequence of events leading up to an error.
Modern web applications are incredibly complex. Even the simplest tasks may require the user to interact with many different systems. Increasingly, these systems are stateful. So when an error occurs, it may be the result of a specific sequence of events across many systems, each in a specific state. In other words, it's complicated.
Honeybadger automatically records client-side and server-side events as users interact with your application. When an error occurs, we display them alongside the backtrace, params, and other error data.
