  • Close errors when you've dealt with them, or ignore reoccurring false alarms.
  • Shows when this error last occurred, and when it first occurred.
  • The error bar shows the title of the error, the URL it first occurred at, and the number of occurrences and comments.
  • By default, Exceptional shows you the most important lines of your backtrace to avoid clutter.
  • A quick click shows the full backtrace.
  • Step through the most recent 30 occurrences. We store session and environment variables, URLs, params, referrers and more.
