We make a large, enterprise-targeted app at my startup. Fullstory has accelerated our search for product-market fit by allowing us to make some significant discoveries in how users use our app.

We could have made all these discoveries by properly instrumenting our code with our own tracking framework. That said, Fullstory provided us a big bang for our buck in [time spent : value provided]; half-day implementation led to all the usage info we could need.

We've gone as far as creating a recurring "Game Tape Friday" meeting where the whole development team sits down and watches 5-10 user sessions together to record bugs and possible UX improvements.

We're not a small website so this anecdote may be of limited value to you, but I would personally give up syntax highlighting before I would give up Fullstory.
