Short answer: PagerDuty and Rootly sit on opposite ends of the incident lifecycle. PagerDuty is the mature, enterprise on-call and alerting incumbent, strongest at paging and integrations. Rootly is a modern, Slack-native incident-management platform, strongest at process, automation, and retrospectives. If your priority is reliable paging with a huge integration catalog, PagerDuty leads; if it is running and learning from incidents in Slack, Rootly leads. Both price per person, though, and most teams want both halves in one place at flat pricing, which is where Pagerly wins.
| Need | Best of these two | Better option |
| Enterprise paging and integrations | PagerDuty | Pagerly for most teams |
| Incident process and retrospectives | Rootly | Pagerly |
| Slack-native workflow at flat pricing | Neither fully | Pagerly |
PagerDuty defined the on-call category. It offers deep on-call scheduling, escalation policies, event intelligence and AIOps, and one of the largest integration catalogs in the market, which is why large enterprises rely on it. If you need to connect hundreds of monitoring and ticketing tools and route alerts with fine-grained rules, PagerDuty is proven.
The recurring criticisms are cost, complexity, and pace. Pricing is per user per month, with the Professional plan around 21 US dollars and Business around 41 US dollars, plus add-ons for advanced features, so the bill grows quickly as your on-call org grows. Many teams describe the interface as dated and the platform as slow to modernize, and renewals can be a point of friction. It is best for large, integration-heavy enterprises. For the full cost picture, see the PagerDuty pricing breakdown.
Rootly is a Slack-native incident-management platform built around process. Declare an incident with a slash command and Rootly opens a channel, assigns roles, tracks a timeline, runs workflow automation and runbooks, and generates structured retrospectives. It has added on-call scheduling, so it can cover paging as well, and it appeals to teams that want to standardize incident response and improve their post-incident learning.
The trade-offs are price and focus. Rootly is a premium product priced per responder or seat, so cost scales with headcount, and its heart is incident process rather than lightweight paging. Teams that mostly need someone to be woken up reliably can find it more platform than they need. It is best for organizations maturing their incident-response practice with budget to match.
PagerDuty and Rootly are complementary more than competitive. PagerDuty is the alerting and on-call engine with unmatched integration depth; Rootly is the incident-response layer that makes the response itself organized and repeatable. Compared purely on paging and integrations, PagerDuty wins. Compared purely on Slack-native incident workflow and retrospectives, Rootly wins. The catch is that adopting both to get full coverage means two premium, per-seat contracts and the integration work to stitch them together. That is precisely the kind of expensive, fragmented stack that modern teams are trying to escape, and it is why a single platform that does both is increasingly the smarter buy.
| Feature | PagerDuty | Rootly | Pagerly |
| On-call scheduling | Strong | Yes | Yes, in Slack |
| Integration catalog | Very large | Growing | Core tools covered |
| Slack-native workflow | Limited | Yes | Yes, end to end |
| @oncall usergroup sync | No | Limited | Yes, automatic |
| AI post-mortems | Add-on | Partial | Yes |
| Pricing model | Per user | Per responder | Flat per team |
PagerDuty was built before Slack became the operations hub, and Rootly, while Slack-native, is priced as a premium platform. Pagerly combines what both do well without their cost model. It is a Slack-native on-call, paging, and incident platform used by more than 1,000 organizations, including teams at 1Password, Disney+, Spotify, and Loom.
Score any replacement on five traits: full workflow inside Slack, predictable pricing rather than per seat, automatic @oncall usergroup sync, modern AI-assisted incident response, and painless import of your existing schedules. PagerDuty is strong on integrations but weak on the Slack workflow and predictable pricing; Rootly is strong on process but premium per seat. Pagerly is built around all five.
PagerDuty and Rootly both charge per person, so a growing on-call org pays more each year for the same coverage, and running both compounds the problem. Pagerly's flat per-team pricing from 19 US dollars per month, plus 4 US dollars per user for paging, keeps cost stable as you scale. See the PagerDuty pricing breakdown for context.
Add Pagerly to Slack, import your PagerDuty schedules and escalation policies from the docs, enable @oncall usergroup sync, validate paging on a few low-severity alerts, then cut over. Most teams migrate in a single afternoon.
Is PagerDuty better than Rootly? They target different jobs. PagerDuty is stronger for enterprise paging and integrations; Rootly is stronger for Slack-native incident process. Neither alone gives you both cheaply.
Does Rootly replace PagerDuty? It can for teams that want incident process plus its newer on-call, but its per-seat pricing and process focus differ from PagerDuty's alerting depth.
What is a cheaper alternative to both? Pagerly, at flat per-team pricing from 19 US dollars per month. See pricing.
Can I import my PagerDuty schedules? Yes, per the docs.
Choose PagerDuty if you are a large enterprise that needs its integration depth, or Rootly if Slack-native incident process is your priority and budget is not a concern. For most teams, though, the better answer is a single platform that does both at a price that does not grow per seat. Pagerly gives you on-call, paging, and modern AI-assisted incident response in Slack at flat per-team pricing. Compare Pagerly vs PagerDuty, check the pricing, or read the docs, then add Pagerly to Slack for free.
