Today, I’m excited to share the Internet’s Largest Incident Response Glossary. It’s a collection of over 500 terms covering on-call, alerting, monitoring, and system reliability. It took us over 2 weeks from ideation to completion of this project and in this post, I would like to share how we approached this beast!

If you’re comparing OpsGenie vs. PagerDuty, there’s something important you need to know right away: OpsGenie is shutting down. OpsGenie has been a trusted ally for incident teams for over a decade. In our Ode to OpsGenie, we celebrated its legacy—from simplifying on-call rotations to reducing alert noise effectively. Atlassian announced that OpsGenie sales will stop on June 4, 2025, with a complete shutdown by April 5, 2027.

With the news of OpsGenie shutting down and everyone looking for possible alternatives, we wanted to take a moment—not just to acknowledge the end, but to rewind and revisit the journey that brought them here. Over the years, it carved out a meaningful place in a competitive market, and in the workflows of thousands of teams. This is a look back at where it all began, what made OpsGenie different, and the mark it leaves behind.

This in-depth analysis examines PagerDuty’s pricing structure for 2025, going far beyond the advertised rates to uncover the true total cost of ownership. We break down the additional fees, essential add-ons, implementation timelines, and ongoing maintenance costs that most organizations discover only after committing.

Atlassian recently dropped a bombshell: OpsGenie is shutting down. If you’re an OpsGenie user, this news probably hit hard. After investing time setting up your alerts, configuring oncall schedules, and training your team on OpsGenie, you’re now faced with finding and migrating to a new incident management solution. We understand the frustration and uncertainty you’re feeling right now. The reactions on Hacker News show you’re not alone in this challenge: Take a deep breath.
