Here at Honeybadger we want to give you a complete picture of your application's health. That's why we include uptime & latency monitoring with all our plans. We've been hard at work making our uptime system even better; making it suitable not only to check web pages, but also APIs. Many of our customers have found Honeybadger Uptime to be a great replacement for NewRelic's alerts, which were recently removed from their more affordable plans.
