Short answer: PagerDuty and Splunk On-Call are both established alerting and on-call tools from the previous generation. PagerDuty is the category leader with the deepest integrations and AIOps, while Splunk On-Call (formerly VictorOps) is tied to Splunk observability and now sits under Cisco with an uncertain roadmap. If you need the broadest integration catalog, PagerDuty leads; if your world is Splunk, Splunk On-Call is convenient. Both price per user and neither is Slack-native, which is why most teams are moving to Pagerly.
| Need | Best of these two | Better option |
| Broad integrations and AIOps | PagerDuty | Pagerly for most teams |
| Alerting close to Splunk | Splunk On-Call | Pagerly |
| Slack-native workflow at flat pricing | Neither | Pagerly |
PagerDuty defined on-call. It offers deep scheduling, escalation policies, event intelligence and AIOps, and one of the largest integration catalogs in the market, which is why enterprises rely on it. If you need to connect hundreds of 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 Professional around 21 US dollars and Business around 41 US dollars plus add-ons, so the bill grows with your on-call org. Many teams call the interface dated and the pace of change slow, and renewals can be a friction point. It is best for large, integration-heavy enterprises. See the PagerDuty pricing breakdown.
Splunk On-Call began as VictorOps and was acquired into Splunk, which is now part of Cisco. It covers the fundamentals of paging: on-call schedules, escalation, an incident timeline, and multi-channel notifications, and it pairs naturally with Splunk observability data. For teams already running Splunk, alerting from the same ecosystem is convenient.
The concerns are direction and cost. Since the Cisco acquisition, the standalone roadmap has looked uncertain to many customers, and that uncertainty alone pushes teams to evaluate alternatives. Pricing is per user, and the workflow is not Slack-native. It is best for existing Splunk shops that want alerting near their observability data.
These two are the closest thing to a like-for-like matchup among legacy tools. Both are mature alerting and on-call engines, both price per user, and neither runs the incident inside Slack. PagerDuty wins clearly on breadth of integrations, AIOps, and enterprise features, so if you want the most capable classic paging platform, it is the stronger pick. Splunk On-Call wins only in the narrow case where tight Splunk observability coupling matters more than everything else, and even there its uncertain future under Cisco is a real risk. In practice, choosing between them is choosing between two products built for how teams worked five years ago.
| Feature | PagerDuty | Splunk On-Call | Pagerly |
| Integration catalog | Very large | Splunk-centric | Core tools covered |
| On-call scheduling | Strong | Yes | Yes, in Slack |
| Slack-native workflow | Limited | Limited | Yes, end to end |
| @oncall usergroup sync | No | No | Yes, automatic |
| Roadmap certainty | Stable | Uncertain | Stable |
| Pricing model | Per user | Per user | Flat per team |
Both PagerDuty and Splunk On-Call were built before Slack became the operations hub, and both price per user. Pagerly was built for the current way teams work. It is 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 and Splunk On-Call are both per-user and not Slack-native, and Splunk On-Call carries roadmap risk. Pagerly is built around all five.
Both charge per user, so cost climbs with headcount. Pagerly's flat per-team pricing from 19 US dollars per month, plus 4 US dollars per user for paging, stays predictable as you grow. See the PagerDuty pricing breakdown.
Add Pagerly to Slack, import your PagerDuty or Splunk On-Call schedules from the docs, enable @oncall usergroup sync, validate paging, then cut over. Most teams migrate in a single afternoon.
Is Splunk On-Call the same as VictorOps? Yes, VictorOps was rebranded Splunk On-Call after the Splunk acquisition, now part of Cisco.
Is PagerDuty better than Splunk On-Call? On integrations and enterprise features, yes. Both are per-user and not Slack-native, though.
What is a modern alternative to both? Pagerly, Slack-native and flat per team from 19 US dollars per month. See pricing.
Can I import my schedules? Yes, per the docs.
Choose PagerDuty if you need its integration depth, or Splunk On-Call only if tight Splunk coupling outweighs its uncertain future. For most teams, though, both are legacy per-user tools, and the better move is a modern, Slack-native platform at flat pricing. Pagerly gives you on-call, paging, and AI-assisted incident response in Slack. Compare Pagerly vs PagerDuty, check the pricing, or read the docs, then add Pagerly to Slack for free.
