Rollbar - best freemium tool for Magento 2 error tracking - Magenaut

Introduction

Rollbar is a freemium tool that I used to track all my Magento 2 sites. There are so many reasons that I have to use it:

I don’t want to use SSH and view the exception.log on a console.
The log isn’t included additional information like Browser, OS, and device type.
It’s inconvenient to share or explain the log file to a non-programmer.
The log file sometimes too big to open.
Logfile doesn’t have a good exception traceback.

This tool is free up to 5000 error events per month. You can visit Rollbar website to see more details about its features.
