I would add sentry.io error logging to this list. Very happy customer. We use them heavily and it’s been really helpful identifying production issues that miss testing.
I don't quite see the point of this?<p>"Crisp chat" - there's tonnes of these things, what makes this one the one to know? Where's Let's Encrypt, which i'd argue is more important than the lot?<p>"10 web services I use and like" would be a better title imo.
