Sentry

Overview

A tool that catches errors and crashes in live apps and websites and reports exactly where and why they happened.

General use

Developers use it to find out when users hit bugs, see the details needed to reproduce them, and fix problems before more people are affected.

Insight

Good at catching errors in live apps and giving you enough detail to reproduce them, which is its clear strength. On a busy app it can flood you with noise until you spend time tuning what counts as an alert. The newer performance monitoring is decent but not a full replacement for a dedicated tool. Best kept focused on crash and error tracking.
