Short answer: Incident.io and Grafana OnCall approach on-call from opposite directions. Incident.io is a premium, Slack-native incident-management platform, while Grafana OnCall is the alerting and on-call layer of the Grafana observability stack. If you want polished incident response in Slack, Incident.io leads; if you live in Grafana and Prometheus, Grafana OnCall is convenient. But Incident.io is expensive and the open-source Grafana OnCall was archived in 2026, so the balanced, durable choice for most teams is Pagerly.
| Need | Best of these two | Better option |
| Polished Slack-native incidents | Incident.io | Pagerly for value |
| On-call inside Grafana | Grafana OnCall | Pagerly |
| On-call plus incidents at flat pricing | Neither | Pagerly |
Incident.io is a premium, Slack-native incident-management platform covering the lifecycle end to end: declaring incidents in Slack, roles and severities, status pages, workflow automation, and its own on-call product. It is polished and comprehensive, and teams pick it when they want a dedicated incident tool and have budget. The trade-off is cost: per-seat or per-responder pricing at the premium end. See our full Incident.io comparison.
Grafana OnCall is the on-call and alerting layer of the Grafana stack, ideal if your metrics and dashboards already live in Grafana and Prometheus. It handles schedules, escalation, and alert routing close to your observability data. The important caveat is that the open-source Grafana OnCall was archived in 2026, leaving the managed cloud path and limiting the self-hosted future, which introduces uncertainty for teams that relied on the OSS version. See our full Grafana OnCall comparison.
These two rarely overlap. Incident.io is response-first and Slack-native, focused on running incidents well; Grafana OnCall is alert-first and observability-native, focused on routing alerts from Grafana. Compared on incident workflow and polish, Incident.io wins clearly; compared on tight Grafana integration, Grafana OnCall fits better. The problem is that combining them means a premium incident platform plus an on-call layer whose open-source future was just archived, so you get cost on one side and roadmap uncertainty on the other. A single, stable, Slack-native platform sidesteps both issues.
| Feature | Incident.io | Grafana OnCall | Pagerly |
| Slack-native incidents | Strong | Limited | Strong |
| On-call scheduling | Yes | Yes | Yes, in Slack |
| Observability fit | Integrates | Grafana-native | Integrates |
| @oncall usergroup sync | Limited | No | Yes, automatic |
| Roadmap certainty | Stable | OSS archived 2026 | Stable |
| Pricing model | Per responder | Stack-based | Flat per team |
Incident.io is premium and Grafana OnCall's open-source path was archived. Pagerly gives you modern, Slack-native on-call and incident response at flat pricing, connecting to Grafana or any monitoring for detection. It is used by more than 1,000 organizations, including teams at 1Password, Disney+, Spotify, and Loom.
Score any tool 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. Incident.io nails the Slack workflow but is premium; Grafana OnCall fits Grafana but carries OSS-archive uncertainty. Pagerly hits all five at flat pricing.
Incident.io prices per responder and Grafana OnCall pricing is tied to the Grafana stack. Pagerly's flat per-team pricing from 19 US dollars per month, plus 4 US dollars per user for paging, stays predictable while you keep Grafana for monitoring.
Add Pagerly to Slack, connect Grafana or your monitoring, import schedules from the docs, enable @oncall usergroup sync, validate paging, then cut over. Most teams migrate in a single afternoon.
Was Grafana OnCall discontinued? The open-source Grafana OnCall was archived in 2026; the managed cloud offering continues, but the self-hosted future is limited.
Is Incident.io tied to Grafana? No. Incident.io is a standalone incident platform that integrates with monitoring tools including Grafana.
What is a stable alternative? Pagerly, Slack-native and flat per team from 19 US dollars per month, integrating with Grafana. See pricing.
Can I import my schedules? Yes, per the docs.
Choose Incident.io for a premium incident platform with budget, or Grafana OnCall if you are committed to the Grafana cloud stack. But with premium pricing on one side and an archived open-source path on the other, most teams are better served by a stable, Slack-native platform that integrates with Grafana. That is Pagerly. Compare Pagerly vs Grafana OnCall, check the pricing, or read the docs, then add Pagerly to Slack for free.
