It is a great Bug Tracking tool when implemented and set up the correct way initially. If you find yourself in the position of having to go through and re name fields on a project level of having to do an overhaul of the user base you will find some frustrations, these are noted in the last question.
[Sentry] is honestly an amazing product. It allows us to detect errors in real time complete with stack traces and any extra accompanying information the developer wants to provide in the alert. With the alerting into Slack it has allowed us to quickly triage and tag in people who need eyes on a specific issue. It would be really useful in any Saas product environment.
We actually ended up using both because New Relic is a more robust overall IT infrastructure monitoring product. However, sentry is more developer oriented on the backend and more client friendly on the front end as far as showing results and the dashboard etc. It can provide product level insights that New Relic does not.
Error tracking is a must in any modern dynamic website or app. By looking into the error notifications I'm able to fix errors before anyone even has a chance to complain about them!
Surprisingly, many website issues aren't showing up in Sentry, because they don't trigger exceptions. I'm interested in seeing if I can use Sentry to catch manually-triggered exceptions for "undesirable states" that my website can find itself in. Of course, that means I have to figure out how to have my client code recognize that it's in an undesirable state...
