Sentry

Today I want to tell you about an amazing tool I didn't know existed when I was starting out as a developer. Luckily, I got acquainted with it as soon as I got into a company with numerous web and mobile apps in production.

Its main purpose is to track errors in your apps. In other words, if the app throws some weird exception in production, you instantly get notified and receive a stack trace*. So, you can see when and why your app crashes and release a patch before all of your users abandon you.

Moreover, there is another feature, that I didn't have a chance to benefit from. It is performance monitoring. Sentry allows you to measure metrics like throughput, latency, failure rate, number of users impacted, and user misery. On top of that, you get a lot of graphs that visualize these metrics, so you're able to keep an eye on changes in performance over time.

What I especially love about Sentry is that there is a well documented library for almost every platform (language/framework/library) which allows you to use it in all of your projects both on frontend and backend. The second thing is that it has a free plan, so you can always try it out if there is no need for third-party integrations or other team members to join.
