FireHydrant vs PagerDuty: What are the differences?

Developers describe FireHydrant as "A simple incident response tool". FireHydrant allows you to maintain an organized log of incidents, the events that occurred during them, and integrations to lift information to the surface that matters. On the other hand, PagerDuty is detailed as "Incident management with powerful visibility, reliable alerting, and improved collaboration". PagerDuty is an alarm aggregation and dispatching service for system administrators and support teams. It collects alerts from your monitoring tools, gives you an overall view of all of your monitoring alarms, and alerts an on duty engineer if there's a problem.

FireHydrant and PagerDuty can be primarily classified as "Monitoring Aggregation" tools.

Some of the features offered by FireHydrant are:

• Incidents - Tie Incidents to components and start keeping track with notes, milestones, and Slack messages. We’ll keep everything organized for when you head into your post mortem.
• Components - Have an API and a Web UI? Add them to FireHydrant as components. Organize your incidents by the components you provide in your application. You can quickly find previous incidents for them too. Components make it easy to report on which things fail the most.
• Slack - We have a deep integration with Slack that allows you to quickly create Incidents, add notes and milestones, and coordinate response. You get an incident specific channel automatically that allows you and your team to coordinate response to any incident on FireHydrant.

On the other hand, PagerDuty provides the following key features:

• Alerting that works (and wakes you up)- When your systems go down, PagerDuty will wake you up. You choose how you want to be alerted - via phone, SMS or email, to multiple numbers, with retries.
• Integrate all your existing monitoring tools- PagerDuty works great with almost all monitoring tools including: Nagios (and Icinga), Keynote, New Relic, Pingdom, Circonus, Red Gate SQL Monitor, Server Density, Zenoss, Monit, Munin, SolarWinds and many others. If it can send email, it will work with PagerDuty.
• Native apps with push notifications- iOS and Android native apps with push notifications and a cross-platform mobile website ensure you can respond to alerts wherever you are, even on the go.
