The TL;DR
Sentry is an error-tracking and performance-monitoring platform to help developers diagnose and fix issues in their code.
-
Errors (think, any event causing an application to misbehave) are inevitable facets of commercial software development (it’s true 😣)
-
Sentry provides a SDK that developers can plug into their codebase to capture errors, and a graphical interface to contextualize and take action on them
-
Sentry is best known for error tracking, but also provides application performance monitoring to better understand how well a team’s app is performing
Sentry is a well-regarded staple for many development teams, and they know it.

The core Sentry product: error tracking
The world of software bugs is vast, and while there’s no established delineation between these pesky terms, we can assume the following for future reference:
Software Error: Any event or condition during the execution of a program that disrupts the normal flow of the code.
There are many classes of issues that may arise during development and execution (i.e. the actual running) of a software application, each with their own quirks and methods for handling.
Sentry is a platform for monitoring and tracking these errors in software applications. By default, it handles and reports any uncaught errors (those not encapsulated in a try/catch block), while also allowing collecting the handled errors. Capturing the errors is just the first step: Sentry also does most of the dirty work in classifying, grouping, and visualizing errors to make them legible and easy to take action on.
