When I started with TrackJS 7 months ago I wrote a Medium article explaining our integration with this tool, which has remained consistent to this point.
TrackJS has been very helpful for finding bugs on a production sites before they are reported by users. I haven’t used the competition recently but when I first settled on trackjs was because it was by far the easiest to set up and get started on for browser-based js apps.
We moved all frontend applications to TrackJS and it has helped us to make incredibly helpful improvements, with impact measurements, fast feedback, alerts, filtering, groups, etc. We've run some benchmarks including other competitors, considering lots of aspects, and TrackJS was our best bet. And I'm really glad to endorse TrackJS - it has helped us a lot!
Have used this product for a couple of years now very pleased with it and get fast feedback with any issues
TrackJS is definitely the best browser errors reporting tool I have ever used! I have tried Newrelic, Muscula and custom solutions but none of them could compete with TrackJS.
The most valuable feature for us is "Users impacted" overview, which basically defines the priority of error, also it helps to filter our the noise that comes from different browser extensions that users have. Great product!
The team at TrackJS are really helpful. This is a quality product that will make any browser based product better.
