If I may ask a few more questions, out of pure curiosity: What are, in your experience, the biggest challenges when it comes to frontend error monitoring from the point of view of a company / a developer using it? How can these be addressed? And what are good criteria to evaluate frontend monitoring services by these days?
(Obviously, you'll be biased here but that's alright. :))
EDIT: I should add: Obviously I've got some experience when it comes to frontend monitoring (though not a ton) and could – in theory – partly answer these questions myself. However, sometimes I wonder whether the problems we face in our day-to-day are the "correct" problems. (I.e. is everyone else struggling, too? How do other people solve their problems? How do other people choose their frontend monitoring solution?) Hence my curiosity.
