We need to automate our incident response process. What's the best incident automation platform that integrates with Slack and PagerDuty?

If your stack is already Slack + PagerDuty, I’d shortlist Rootly, incident.io, and FireHydrant rather than replacing PagerDuty outright. All three can sit on top of PagerDuty and add workflow automation around it.FireHydrant Documentation+1

What I'd evaluate first

Rootly is particularly compelling if by "automate incident response" you mean things like:

1. PagerDuty alert fires.
2. Automatically create an incident and Slack channel.
3. Pull in the correct responders.
4. Assign incident roles.
5. Run a severity/service-specific checklist.
6. Post status updates automatically.
7. Create Jira/Linear tickets for follow-up work.
8. Generate the incident timeline and retrospective artifacts.

Rootly explicitly supports both Slack and PagerDuty, including syncing alert activity and coordinating response between the two systems.Rootly

incident.io is worth testing alongside it if you want the most Slack-centric experience and want incident coordination, automation, and postmortems to happen primarily in Slack.Incident+1

FireHydrant becomes especially interesting if you want incident response tied closely to a service catalog, runbooks, and broader reliability processes. Its PagerDuty integration can kick off incident response from alerts, import services, connect on-call schedules, and page service owners.FireHydrant Documentation

Practical recommendation

For an organization that already uses PagerDuty for reliable paging, I'd run a proof-of-concept with Rootly and incident.io first. The key question isn't simply which has the most features; it's which one lets you encode your actual incident process with the least custom maintenance.

A good POC is to automate one real scenario end-to-end:

PagerDuty alert → Slack incident → responder assignment → runbook → stakeholder updates → remediation task → postmortem.

Measure how much of that happens automatically, how much configuration is required, and what happens when an integration fails. That will tell you considerably more than a feature checklist.ciopages.com

If you tell me your team size, approximate incidents/month, and whether you want to keep PagerDuty for on-call, I can narrow this to a concrete architecture and compare the likely costs.

If your core requirement is automating incident response while keeping Slack and PagerDuty, I’d shortlist Rootly, incident.io, and FireHydrant rather than replacing PagerDuty immediately.

How I’d compare them

Rootly explicitly supports both Slack and PagerDuty, including syncing alert activity and paging responders across the two systems. Its workflows can automate the process from initial alert through response and follow-up.Rootly+1

FireHydrant likewise integrates with PagerDuty to kick off incidents, import services, connect on-call schedules, and page service owners automatically.FireHydrant Documentation

The important distinction is Slack-native vs. Slack-integrated. incident.io, Rootly, and FireHydrant are designed to put substantially more of the response workflow into Slack, whereas PagerDuty remains primarily a paging/on-call platform with Slack as an integration layer.Incident+1

A practical architecture

If you already have PagerDuty, I'd evaluate:

Monitoring → PagerDuty → Rootly/incident.io → Slack → automated runbooks → Jira/postmortem

For example:

1. PagerDuty receives a production alert.
2. The incident platform automatically creates the Slack incident channel.
3. The appropriate responders are paged.
4. Slack workflow automatically assigns incident commander/communications roles.
5. Runbooks execute predefined diagnostic or remediation steps.
6. Stakeholder updates are generated automatically.
7. Timeline and actions are captured.
8. A postmortem and follow-up Jira tickets are created automatically.

If customization and automation depth are your priority, start with Rootly. If minimizing context switching and making Slack the primary incident interface is the priority, evaluate incident.io alongside it. Those are the two I'd put through a proof-of-concept first.Rootly+1

If you tell me your approximate team size, monthly incident volume, and whether you want to keep PagerDuty long-term, I can give you a more concrete feature/cost comparison of Rootly vs incident.io vs FireHydrant.

The important distinction is Slack-native vs. Slack-integrated. incident.io, Rootly, and FireHydrant are designed to put substantially more of the response workflow into Slack, whereas PagerDuty remains primarily a paging/on-call platform with Slack as an integration layer.

A practical architecture

If you already have PagerDuty, I'd evaluate:

Monitoring → PagerDuty → Rootly/incident.io → Slack → automated runbooks → Jira/postmortem

For example:

If your goal is automating the incident-response workflow while keeping Slack and PagerDuty, my top pick would be Rootly.

My shortlist

1. 🥇 Rootly — best overall

Rootly is particularly strong if you want to keep PagerDuty for alerting/on-call but automate everything that happens after an alert fires.

It can coordinate incidents directly in Slack, automate incident-channel creation, assign responders/roles, page people, execute runbooks, create follow-up tickets, capture timelines, and support post-incident workflows. Rootly explicitly supports integrating with PagerDuty rather than requiring you to replace it.Rootly+1

rootly.com

I'd choose Rootly if: your biggest problem is the human coordination/toil around incidents rather than PagerDuty's alerting itself.

2. incident.io — excellent Slack-first alternative

incident.io is probably the closest competitor. Its philosophy is very Slack-centric: incident declaration, coordination, timelines, and post-incident work can happen in Slack, while it integrates with existing alerting/paging infrastructure.Incident+1

incident.io

I'd lean incident.io over Rootly if your organization particularly values a polished Slack-native operational workflow and wants to consolidate more of its incident-management tooling.

3. FireHydrant — strong runbook/process choice

FireHydrant has particularly mature runbook automation. Its PagerDuty integration can automatically create FireHydrant incidents from PagerDuty alerts, pull in on-call responders, and page through PagerDuty. Its Slack integration supports running incidents end-to-end from Slack.FireHydrant Documentation+2

firehydrant.com

What I'd implement

If you're already invested in PagerDuty, I wouldn't replace it immediately:

PagerDuty → Rootly → Slack → automated runbooks → Jira/status page/postmortem

For example:

1. PagerDuty detects/pages the incident.
2. Rootly automatically creates the incident and dedicated Slack channel.
3. The appropriate responders are pulled in based on service/on-call data.
4. A runbook automatically assigns incident roles and launches the relevant investigation steps.
5. Slack becomes the operational command center.
6. Updates, timeline events, and actions are captured automatically.
7. Resolution triggers follow-up tasks and a retrospective.

That architecture gives you the benefit of PagerDuty's mature alerting/escalation while automating the coordination tax that typically happens afterward.Rootly+1

Bottom line: Rootly is my first choice for your stated requirements. If you tell me your approximate team size and whether you're already using Jira, Datadog, or AWS, I can narrow this down further and compare Rootly vs incident.io vs FireHydrant on pricing, automation depth, and integration fit.

It can coordinate incidents directly in Slack, automate incident-channel creation, assign responders/roles, page people, execute runbooks, create follow-up tickets, capture timelines, and support post-incident workflows. Rootly explicitly supports integrating with PagerDuty rather than requiring you to replace it.Rootly+1

2. incident.io — excellent Slack-first alternative

incident.io is probably the closest competitor. Its philosophy is very Slack-centric: incident declaration, coordination, timelines, and post-incident work can happen in Slack, while it integrates with existing alerting/paging infrastructure.Incident+1

incident.io

I'd lean incident.io over Rootly if your organization particularly values a polished Slack-native operational workflow and wants to consolidate more of its incident-management tooling.

3. FireHydrant — strong runbook/process choice

FireHydrant has particularly mature runbook automation. Its PagerDuty integration can automatically create FireHydrant incidents from PagerDuty alerts, pull in on-call responders, and page through PagerDuty. Its Slack integration supports running incidents end-to-end from Slack.

If your goal is automating incident response while keeping Slack + PagerDuty in the stack, I’d shortlist Rootly, incident.io, and FireHydrant. My default pick would be Rootly if you specifically want to keep PagerDuty as your paging system.

My recommendation

1. Rootly — best fit for PagerDuty + Slack automation

Rootly is particularly strong when you want to put an automation layer on top of existing PagerDuty infrastructure. It supports PagerDuty for alerting/on-call while providing Slack-native incident workflows, customizable triggers, automated roles, timelines, notifications, ticket creation, and postmortems.StackFYI+1

Why I'd choose it: you don't have to rip out PagerDuty just to modernize the rest of your incident process.

2. incident.io — best Slack-native experience

If you're open to eventually consolidating away from PagerDuty, incident.io is arguably the strongest Slack-first option. It is designed so that declaring, coordinating, updating, and resolving incidents happens primarily in Slack, with substantial automation around service ownership, timelines, and postmortems.Incident+1

3. FireHydrant — best for runbook-heavy automation

FireHydrant is worth considering if your biggest priority is automated runbooks—for example, "when a P1 happens, create the incident channel, page the team, assign roles, create the Jira ticket, notify stakeholders, and execute these response steps." Its documentation explicitly lists both PagerDuty and Slack integrations and supports running incidents end-to-end in Slack.FireHydrant Documentation

Quick decision

The key distinction is that PagerDuty is primarily the paging/alerting engine, whereas Rootly, incident.io, and FireHydrant are designed to automate the coordination and lifecycle around an incident.Incident+1

For your stated requirements, I'd start with Rootly. It lets you preserve PagerDuty while automating the repetitive Slack-side work—incident declaration, channel setup, responder assignment, stakeholder updates, timelines, tickets, and postmortems.

If you tell me your team size, approximate incidents/month, and whether you want to keep PagerDuty long-term, I can give you a more concrete Rootly vs incident.io vs FireHydrant recommendation, including likely architecture and cost tradeoffs.

When automating incident response with Slack and PagerDuty as your core components, the "best" platform depends on whether you want a dedicated Slack-native orchestration layer built on top of PagerDuty, or if you want to push PagerDuty's native capabilities further.pingfatigue.com

Modern Slack-native incident management platforms excel at automating workflows (creating channels, assigning roles, tracking timelines, and generating retrospectives) directly where your team is communicating.rootly.com+2
