Rootly vs PagerDuty — An SRE's Honest Take (2026)

TL;DR

PagerDuty is the industry standard for on-call alerting and escalation. Rootly is a newer player focused on incident coordination — think Slack-native war rooms, runbooks, and post-incident workflows. They're not direct replacements for each other, but there's growing overlap.

On-Call & Alerting

PagerDuty dominates here. Decades of integrations, robust escalation policies, and a mobile app that will wake you up at 3 AM. Rootly has basic alerting but it's not their core strength.

| Feature | PagerDuty | Rootly | |---------|-----------|--------| | On-call scheduling | Excellent | Basic | | Escalation policies | Advanced | Simple | | Mobile alerts | Native app | Slack / SMS | | Integrations | 700+ | 50+ |

Incident Coordination

This is where Rootly shines. When an incident fires, Rootly automatically creates a Slack channel, pages the right people, attaches runbooks, and starts a timeline. PagerDuty added similar features with their Incident Workflows, but it still feels bolted on.

I used PagerDuty for 2 years before trying Rootly at my current job. The difference during a real incident is night and day. With PagerDuty alone, our "process" was: get paged, manually create a Slack channel called #inc-something, paste a Notion runbook link, and hope people joined. Half the time someone forgot to update the status page. Rootly automated all of that — one Slack command and you get a dedicated channel, the right people paged, the runbook pinned, and a timeline recording every action. Our MTTR dropped from ~45 minutes to ~25 minutes, mostly because people stopped wasting time on coordination overhead. The auto-generated retro docs saved us another 2-3 hours per incident on postmortem prep. That said, Rootly's alerting is basic — we still use PagerDuty to actually wake people up at 3 AM. Rootly tried to sell us on replacing PagerDuty entirely but their on-call scheduling isn't there yet. The combo of PagerDuty for alerting + Rootly for coordination costs more ($21 + ~$15 per user/month) but it's genuinely the best incident workflow I've used.

Post-Incident / Retros

Rootly generates retrospective documents automatically from the incident timeline. PagerDuty's postmortem feature exists but is bare-bones compared to Rootly's templates and action item tracking.

Pricing

PagerDuty starts at $21/user/month (Professional). Enterprise pricing gets expensive fast with large teams. Rootly's pricing is less transparent — you'll need to talk to sales — but teams report it's competitive, especially for the coordination features you'd otherwise build with duct tape and Slack bots.

When to Choose What

• Choose PagerDuty if on-call alerting is your priority, you need hundreds of integrations, or your org already uses it. Also consider OpsGenie as a cost-effective PagerDuty alternative, especially if you're in the Atlassian ecosystem.
• Choose Rootly if your incidents are Slack-heavy, you want automated retros, or your current incident process is a mess of manual Slack channels.
• Use both — many teams use PagerDuty for alerting and Rootly for coordination. They integrate well together.

Bottom Line

There's no single "best" tool here — it depends on where your incident process hurts the most. If you're drowning in alerts, PagerDuty. If your incidents are chaotic Slack threads with no follow-up, Rootly. If budget allows, running both is genuinely the best setup I've seen. Of course, incident management only works when your monitoring catches problems first — check out our Datadog vs New Relic comparison or Sentry vs Bugsnag for error tracking.
